- Today's question from Achim H. is, "I know it's been debated to death, but I'd like to know your thoughts on how many megapixels do we need? I am about to upgrade to a new camera body and am torn." Achim is right about this being a popular question, with some iterations being, "How many megapixels do you need for photography?" or "How many megapixels is good?" Regardless, David goes in depth in this video and tackles everything one needs to know about megapixels, image quality, image display, and more.

THANKS SO MUCH FOR WATCHING! - แนวปฏิบัติและการใช้ชีวิต
![[UNCUT] รัฐสั่งหยุดปล่อยคลื่น! แต่หยุดพลังปะทุ “น้องหญิง” ไม่ได้ I คนดังนั่งเคลียร์](http://i.ytimg.com/vi/RmQh47eIiV0/mqdefault.jpg)
Still using a 16 year old D700 at 12.2MP, still producing stunning looking images, with incredible depth, clarity and image quality that blows my mind...! Best overall DSLR ever made, IMHO.
Great.I used a D700 for years doing Wedding photography. Was excellent. Left it and sold all my gear but now semi retired and returning to photography with a Z6 II. Not sure that I am better off. Cheers from Australia.
Quite agree. I replaced my D700 with a Z 7. The only advantage the 46mp Z 7 has is croppability- in fact the D700 images look better. The Z 7 pics look a bit gritty, like the camera can see better than your eye can. I've kept the 700!
I totally agree.
16 to 24 Mp is the sweet spot
You can use old lenses with lots of character and 3D
36 and up need oversharped lenses with flat clinical rendering
Now I feel embarrassed and inadequate with my "mature" 16 MPixel Olympus OMD5 😂 BUT I recently won the silver medal in an international underwater photography competition in Egypt. I was competing against the Z8's, R5 and the like. I hope to be able to get OM1 MARK II soon 😊
Bravo! I just purchased an OM1 MII. Went from a ff Sony a74 and couldn't be happier. The size and ergonomics so much more fun to use.....
Remember om-1 only have 20MP 😉 but that's more than enough 💪 unless you want to print humongous posters.
No you were competing against the others vision not their gear. Gear is only a part of the equation. Sometimes a very small part. No different than a hammer or a wrench. It is a tool thereby an extension of the Craftsman but I suspect you know that. This is for the others lol.
That’s because you wont it not because of your gear- because it’s you. You create the image, not your OMD5 or if you had it, the Z8 or R5. Congrats!
Pics?
I sold my Fuji XT30ii (24MP) and continued shooting my Nikon D700 (12MP) - For the images are just better, despite the lower resolution.
The D700 is full frame, whereas the XT30 is crop sensor… The D700 WOULD produce better images with the “lower” megapixel count due to the 12mp being larger photo sights spread over a full frame sensor. The 24 megapixels are crammed into a smaller sensor thus creating smaller photo sights, leading to a lower quality image.
A friend of mine from photo school shoots with a Canon with around 20 MP and has his work on magazine covers and billboards. He shoots for a few different boating and water Skiing companies.
'You need more pixels!' - who says? - Camera sales department! After 25 years of experience in printing and photography industry I confirm you can absolutely get by with 12 megapixels for offset or digital prints. In case I might need a crop, I rely on optics, not megapixels, so I take more zoomed shots. Also mind the limits or sweet spots of your optics, beyond them you'll get blurry images, the more megapixels the more blurry.
Well said ‼️👍🏻
Not for high end commercial work
Yes. more cowbell.
nobody's talking about your prints
Answer is obvious. if you don't know what your deliverables are, then you have a bigger problem than megapixels.
Hey man, what do you mean by optics sweet spots? And how do I find it for my lens?
The best video I've seen on Megapixels. You did a great job at explaining it and you did it in less than 15 minutes. I think the second most asked question I get from amateurs, right behind; "What kind of camera do you have," is "How many megapixels is it?"
My philosophy for everything, not just mega pixels is "It's better to have it and not need it that to need it and not have it." Sometimes I make insanely tight crops for posting on social media and they work very well from my 42 MP camera, not from my 6.2 MP original DSLR.
I've just part exchanged a Fujifilm X-T3 (26MP) for a shiny new X-T5 ((40MP). What persuaded me was the IBIS in the X-T5 - I would have been very happy to have 26MP again, with better dynamic range etc etc. But when travelling, which is when I take most of my photographs, the IBIS makes a huge difference for interior shots. And of course you can't go back and reshoot if you're on a trip!
There is no significant difference in dynamic range between X-T4 and X-T5, the only difference are that you can shoot 1/3 of a stop faster with the X-T4 which not is much and more than zeroed out with the IBIS in the X-T5, but you will have a BIG advantage with the X-T5 having more megapixels.
Well upscaling from 26 to 40 is pretty good and if your glass is good a lot of times you can make them essentially the same image
I never used all 6 mp on my Pentax Wipio. Chose the "2mp" setting so most files were around 1mp. Printed detailed, colorful 8x14 prints on my HP.
I use a PhaseOne IQ3-100, a 100mpx digital back, for fashion photography. It gives me an incredible amount of options for both significant cropping, as well as amazing details for retouching. In the end however, when all is done, the ending images will always get scaled down for social media / online use.
I love PhaseOne cameras. I've rented a few for shoots. The IQ3 100MP Trichromatic digital back for Hasselblad H is outstanding.
Great video! I am a hobbyist and shoot with a Nikon D750 (24 megapixel). I like it because it’s a good low-light camera.
Hi Dave I’m 76 & been taking photos since the late 50’s I use a Fuji xe2s 16 megs APSC and just enlarged a photo to 16x24 & wow it came out incredible (taken with Fuji 18-55 zoom) so you are correct great video
Individual sensor character combined with lens rendering has always felt significantly more important to me. My current body is 12 years old as of 2024. I can use the photos SOOC, which was never the case for my newer kit.
Great videos. Covers the basics perfectly for new users.
My current cameras are 26, 33 and 61MP. Whenever I do a shoot with the 26 or 33 and the shoot goes really well I'm disappointed that I didn't use my 61. I love doing Dutch twists and other unusual crops in post and want a high resolution image at the end of the process.
I have Sony A7iii with 24mp and I am tempted with A7iv 33mp, that I decided I will jump to only if I have to. 24mp is a sweet spot for all styles of photography with me, but I do crop a bit in wildlife photography and my pictures would benefit from a small jump in pixels. As to the video - good job! 👍❤️
Thank you. I have used gigapixel on 10 megapixel photos. Crop in on almost any photo stunning results with the software
8 years I was using 18 megapixels crop sensor camera from 12 years ago model lineup and was completely happy with it. Half year ago I upgraded to the 24 megapixel camera and still with the crop sensor. It’s more than enough for all my needs, even when I do relatively big prints (110x70cm). To my own opinion the megapixel race is way overhyped. Yes, I understand that in some cases, like wildlife photography, for example, it can be necessary, but in most of other cases… You can have 24,18,12, even 10 megapixel camera with fast medium range glass and get much better results than some other with 100 megapixel cameras. Just stick with your skills and art vision first, and later you will see if you need more resolution or not.
Simple answer: all of them. LOL
My first digital camera was a 2mp Kodak, it was fine at the time but looking back, I do wish I had more pixels. My first dSLR (Canon 20D) was just over 8mp - on a 4k monitor, the images still hold up fine. I've had several other cameras since, including my newest camera the Sony A7R V - a 61mp monster - with an option to create 240mp composite images too. Early on, there was a race for more megapixels - but today, we have reached a spot where the megapixels are enough for most folks, thus other features are more important. Today, there are just pros/cons. For example, I know my A7R V doesn't have best-in-class low-light performance and the video capabilities are impaired because the sensor is _too_ big. However, I wanted that camera for landscape, not video. I already have a very capable A7C (24mp) that is an excellent hybrid camera (a travel version of the A7III) - which is still my general travel buddy.
I would say, for today, the sweet spot is in the 20-30mp range. That's a decent starting point for new mirrorless/dSLR cameras. Only go higher if you know you want it and are willing to put up with the compromises more pixels introduces - but that range provides enough megapixel overhead that folks can crop a bit and still have exceptional prints and/or look amazing on a 4k display.
The other issue is equipment size and lenses to suit the larger sensors which can get very large and heavy. My Olympus E-M1 Mk II uses much smaller glass so when I go on holiday I have much less weight to cart around and I can take 2-3 lenses in a small shoulder bag. This is more convenient and even makes it so you take the camera more locations. When I had a bigger camera and glass I would sometime just not take it because either it was too big or heavy. I am very happy with the 20mp picture quality so that’s my compromise… and it is always a compromise, if only because of price of larger sensor gear and glass. Really liked the article and great examples… Thanks mate👍😊
Canon EOS R6 is my main camera and only has 20mp and it does an amazing job.
An amazing job is subjective; your comment would have been complete if you had stated what is the maximum print size you can get from your camera when printed at 300 DPI without digital manipulation
My main camera was the Canon 6D (20mp) for many years. Excellent camera - one of the best Canon dSLRs ever made. Still a worthy camera for astrophotography. It would be a worthy camera to pickup second hand for beginners.
The higher the MP rate on a sensor you go, physics start kicking in in terms of light gathering capabilities. And whilst there are certain technologies to counteract that (backside illumination, or some 'cute' software tweaks) the size of the photosite on the sensor is critical in terms of how many photons are going to be detected per site. In most circumstances, up to 20 MP will be plenty for most, especially when printing (and in most homes that'll tend to be no higher than A4 sized). If you are the kind of person who needs to crop viciously into images, either because of your choice of lens at the time, or, just for composition reasons, then a higher pixel count will counteract loss of resolution when you blow up the image. As most people share on social media and other places like that, you don't need a megapixel machine frankly. It depends on four general things: 1) do you crop a lot? 2) do you print a lot (large format especially, 3) are you limited by optics at your disposal? 4) is dynamic range/ high ISO performance important to you?
I use a A7 III (24mp) and it´s more than I need for the large prints of my landscape photos. For portraits, that are printed in medium size, is also more than enough. So it´s like you said, from 20 to 24mp is good enough for professional photographers and more than enough for us amateurs.
In my photo days, I shot mainly Tri-X on any of the cameras I had. That ranged from the Pentax Spotmatic F to my current Nikon F2. No matter what, grainy Tri-X produced great 11x14 prints. Looking at that photo from the correct distance, you don't notice the grain. You see an image that is sharp. Today I am happy with a 24/26 mp camera, though I do have a 61mp camera for those times I shoot macro. The one thing to consider when taking portraits of people is that you will capture every pour, every hair and every flaw on that person's face. A 61mp camera (Sony A7CR or the 42mp A7R3) will make extremely sharp photos worthy of a 20x24 inch and larger poster. I actually think the 42/44mp sensor to be perfect. The rest is gravy.
Need an addendum to explain the fact that the higher the MP, the sooner diffraction sets in. E.g., if for a given lens, diffraction sets in at f/11 on a 45MP FF sensor, it will set in at f/8 on a 60MP FF sensor.
For a 6x4 inch print that you hold in your hands, you need 2 megapixels; printers and paper usually can't handle more, and you won't notice additional detail anyway. This doesn't scale proportionally because we tend to view larger prints from a greater distance, so a larger print from the same 2MP image might still look good, while with 4MP, you can inspect closer and see more details. Therefore, even 10MP is adequate and allows for some generous cropping. As for digital viewing, it depends on how strongly you want to do pixel-peeping, which isn't necessarily reflective of typical photo viewing, it's a different kind of activity. Without zooming in, a 2MP image is still a suitable size for sharing online. With a 2x zoom and bilinear filtering (typical for photo viewers), a 2MP photo doesn't appear pixelated, 2x zoom permits seeing more detail on a typical 26-inch full HD display, placed at an arm's length from the eyes without apparent pixelation.
I believe this video addresses all these points effectively, but some aspects may be missing or perhaps I didn't pay close enough attention. One crucial aspect is the actual resolution of the lens. Some popular yet pricey lenses like the EF 28-70mm f/2.8L can provide up to 19MP at best, while some inexpensive kit lenses can't exceed 8MP.
However, because of the characteristics of sensors, particularly those using the Bayer matrix, increasing megapixels does indeed enhance resolution. Here, pixel-shift technology stands out (not present in Canon or Nikon to my knowledge). It counters the Bayer matrix's limitations by virtually aligning each pixel (red, green, blue) behind one another by quickly shifting the sensor during the capture, eliminating the need for actual debayering. This process helps to mitigate some of the limitations of the Bayer matrix arrangement, such as color moiré and aliasing artifacts and improves apparent resolution of the image. Therefore, the type of sensor significantly impacts resolution too, not just the pixel count. But again, if the lens does not offer sufficient resolution, even the most advanced sensor won't improve the situation. And, after all, eventually you scale everything down, as mentioned in the first paragraph, so this becomes irrelevant. What matters in your picture is how it's composed, the lighting, the shadows - that's what defines a good picture, not the number of megapixels.
Thank you so much @david for taking up my question. Coming from an APSC with 24, I went for the R5 in the meantime, as I expect the 45 will give me ample room for straightening out the unavoidable but unwanted angles in certain architecture shots as well as a lot of freedom for my studio portraits. The first couple of sessions were absolutely great so far. 🙏🙏🙏 Cheers, Achim
R5 is a fantastic camera!
I shoot with the Canon R6 I with 20 mp. Love the low light capability. I can even crop and print portraits with really no problems.Yes. invest in good glass and take some photo lessons.
My camera, as set shoots ~26 MP raw files on a nominally 20 MP sensor, I haven't figured that out yet. For me, 20+ is going to be the sweet spot, enough for the cropping I would do, mostly correcting the horizon and still gives nice results.
You did bring up a good point about when one needs to crop massively that more is better. But I personally never have been in that situation.
If you expose and compose correctly it's amazing how little you need. I shot a wedding last year with a Nikon D300S (12mp) because it was outdoors and I could get 8fps. The clients wanted some enlargements as large as 12x18 and were still amazed at the images. I've never had a client ask how many megapixels my camera has.
Good analysis... with the same answers I've heard for decades, just higher pixel counts. The greatest advance over that time has been in smartphone cameras, which are what most photographers now use to shoot most of their stills and videos. To answer the question of what you "need" from a digital camera today, I'd ask where the phone is not meeting your needs.
You nail a point I've been talking about for years... mega pixels means didly squat, when stretching an image for a billboard. I shot an image for a rural school that was used on a billboard advert on a Canon 70d, and at that size and viewing distance, the mega pixel count was just fine... I can attest that there was nothing wrong... even my pixel peeping butt was totally satisfied with the results, and I usually disavow All my photos every 6 months. (It's an artist perfection thing)
As a fun point of physics and optics, the denser (smaller and more compacted) your sensor sites are, the more prone you are record defraction errors in your lenses. Given the physics and limitations of light and lenses, there is an optimum density of pixels before you hit the point of diminishing returns and cross over into unnecessary technological "overkill." With a crop sensor, that point is about 24 mp. With a full frame, it's about 45 to 50 mp. With a medium format sensor, it's about 100 to 150mp. Bigger sensors (woth the appropriate circle size lenses) can get a much narrower depth of field at a given focal length. But, of course, your printing process can and does cost you resolution, in which case a lot of defects in resolution go unnoticed. You can enlarge a 10 to 12 mp image as well as you can do the same with old 32 ASA pan film before the image goes to heck in a hand basket. Personally, I like the max megapixels I can get for given format so I can crop to my heart's content. I still professionally shoot everything between an old 5D MK II up to a R5 depending upon what I want or need.
And if you do find you suddenly need more resolution after the fact, Adobe's new AI Super Resolution does an incredible job of upscaling RAW files. Effectively indistinguishable from the pixel shift function found in many modern cameras. As long as your image is in focus, properly exposed, and not shot too high on the ISO scale, it works brilliantly. At this point, I think 24MP on FF and APS-C cameras is plenty good enough for 95% of applications.
My current Cam is "only" 24MPs but many of my old photos taken with 10 and 12MP cameras have been printed in field guides and authors of those books never had any issues with no of MP used for taking photo as long as the photos were sharp.
I like being able to crop heavily, especially when photographing sports and wildlife and when making videos. So I’m very happy with my new Fuji X-T5 with its 40 megapixel sensor.
People seem to forget that 4K is just 8.3 megapixels and that the most common way photos are presented is 1920x 1080, a quarter of 4K. My Canon 5D has a full-frame 12.8 MP sensor, and in its day it was the absolute cat's meow. And honestly, in image quality terms, it still is. It can't do everything my 24.2 MP APSC R50 or my 20.2 MP APSC 70D can do, but that's why I have more than one camera.
I'm shooting with the classic Canon 5D II (in production 2008-2012). It's a 21.1MP, and I'm really impressed with the image quality! I paired it with a 24-105 L f4, 70-200 L f4 non-IS, and a nifty f1.8 stm.
I used to shoot weddings and senior portraits with 5-6 megapixel cameras, and frequently printed 16x20 prints with no problem. (Does anyone remember the Olympus E-20N??) I love being able to shoot at 20-30 megapixels so I can crop in tight if needed.
Yeah but what is the maximum print size you can get at 300 DPI?; occasionally even seasoned amateurs will need to make 48"x36" prints, or 48"x12" panoramic prints with a viewing distance of 5'ft, unless a 24MP sensor can deliver that with very little image deterioration it isn't enough.
I still shoot weddings with my Nikon D3s, LOL! You are right about cropping so I am constantly aware that eacg sgot HAS to fill the viewfinder. Not entirely sure how you arrived at your “needed” MP size for printing as I’ve had clients print 24x36 prints with a 10MP image shot from a Canon 1D3., and one client printed a wedding photo 30x45 from a 12 MP photo. That said, today’s cameras as stellar. I still like the high ISO performance from my Nikons so I don’t plan on changing anytime soon but new photographers looking at cameras nowadays have exciting choices to choose from.
This is about the best explanation and rundown on the subject as I have seen. Excellent. Thank you David, and Adorama. Great question, Achim H. Many will be glad you asked. I am.
Great video, I would add that the extra MP are like adding a 3x, 4x, or more teleconverter because of the huge ability to crop with little loss. Also, higher res means you need to use higher shutter or tripod to not record any shake. Lastly, having shot Kodachrome as a young man, my D850 is my current Kodachrome.
I've been shooting in the 20-30MP range for quite a while and have no real need or desire to make my main camera body higher resolution for the bulk of my shooting. I do have an R5 that I use for very specific use cases, but otherwise, it's all R6 and R6II bodies, and man, they are excellent.
I do some extreme cropping, so 24 is better than 12. Also more versatile for use as stills in video that are zoomed/panned in post.
Thank you David! I'm still using my D60 and D700, 10 and 12 MP. It's enough and nobody has complained.
I have a Sony A1 and A7R5 with plenty of detail. But when I travel to European I used an OM-1 at 20MP and can print a 24x30 at home on my Canon Prograph 2000 and it really would be hard to tell the difference. Just less flexibility if you do crop a lot obviously.
Megapixels sells cameras.
PixeL size can be forgotten but should always always be included in the discussion
So when they rate megapixels it should say this many and this size on this area of sensor
Excellent breakdown David. Thank you!!
Thanks for sharing.
To scan most of the detail on a 35mm photo, you'll need about 864 x 0.1, or 87 Megapixels. That's about 8128 DPI. But in practice, consumer lenses and higher ISO films don't record that much detail. Scanning more than about 3048 DPI (12.4 MP) usually just increases the visibility of grain
Great explanation!
Good info, thanks.
I'd say for most printing at normal viewing distances (say anywhere from 12 inches or 1 foot to say 60 inches or 5 ft away) 240-300 dpi should be a good target, and by doing some math, even for a larger print at 240 dpi (say a 13x19 print) you can still easily do that with a 20MP camera (technical 18MP if you don't crop at all). So I think the real big question you need to ask yourself is what is the print size (and viewing distance) and how much do you usually crop. If you're a heavy cropper, than maybe go a bit higher on resolution (you may not need 45MP if you're only doing 13x19 prints and crop a lot, but something like 30 or 36 MP may be more reasonable and a bit cheaper in terms of cost of the camera and you're not paying for pixels you may not need). As for the file size concerns, many cameras do have a lossless compressed mode, which can compress even a 45MP image into around a 50-70MB image depending on the manufacturer. Of course you can also use a lossy compression format which will cause you to lose some detail but those files can be much smaller (perhaps even half or 2/3 the size of alossless compressed file from the camera camera) but you may lose some image quality in the process. But memory cards are quite cheap and so are HDDs and even larger SSDs (like 1-2TB SSDs can be had for about $80-$130 depending on what you get). HDDs are even cheaper now and you can easily get a 4 or 8TB for about $80-$150 as well. So I wouldn't necessarily worry too much about file size unless you shoot A LOT of images, bu even so card capacities have gone up significantly and costs have come down drastically both on memory cards, SSDs and HDDs. So I wouldn't necessarily let file size dictate what resolution camera you buy or what file format you use, again UNLES you are limited on space and/or your shoot A LOT of photos (like 1-2 TB or more per year of photos, which is a lot -- and some people do, but for most people -- the average enthusiast, it's usually not a huge issue and again, memory and storage has become quite cheap lately).
Very detailed and informative, thanks.
Great detailed video
I've had 8 MP photos from my 1D2N printed on billboards and city buses and they look amazing. 24 MP on my R6 II can be used for anything. I've also upscaled to match the R5 and I can't see any difference most of the time, even viewed at 100% on a 5K monitor. If I use any sort of advanced upscaling, I can make my R6 II files look more detailed/better. But even then, when printed, I don't see much difference from either cam. That's why I saved $2000 and got the R6 II and got a lens. Also the AF accuracy made a bigger difference to sharpness than MP... and the R6 II has better AF than the R5.
And everything said above also applies to cropping. Again, you just upscale your output from LR or ACR to what you want, or use Superscale feature (or a good AI upscaler). But I don't crop.
A follow up question. How about software that enlarge images in post production. How many pixels does it add and is the quality good enough that you can actually crop even closer to your subject without losing quality?
YOU HAVE GOT IT EXACTLY RIGHT. i shoot for prints .I have a Epson stylus pro 9800 a canon 6d and a 5ds and use photoshop cs6 all of which are obsolete in todays world
but there is no logical to upgrade any of these they all work .For prints i do not need high dynamic range or 40 frames per second ..The 5ds with a good lens is still a good camera today
Damn such an instructive session!
Excellent coverage of the topic. Also, a great example of when higher resolutions are useful.
One of the most helpful videos I've watched ! Thank you !
An excellent presentation on the whole topic. For my purposes, I do like to crop and prefer higher resolutions for that reason & I chose the Nikon Z8 for its 45 MP resolution.
I shoot the Z9 and most of my zoo photo work is in DX mode at 19.1MP. They love the quality and MB size of the files.
Thanks for your detailed explanation David. I have more modern mirrorless and higher res kit but I still reach for my 12mp D700 regularly. I just can't part with it. I think it was ahead of its time. If picky, no bluetooth, wifi, video and it blows highlights more readily in a very bright sky but thats it, Combined with a good prime better, than more mp in my view.
Thankx for the video, good thoughts on all the aspects surrounding Megapixels ! I have an EOS R with 30 MP. I think it is a good middle ground. The files are not too overwelming in size (30-40MB) but it still gives plenty of cropping capability. A year ago I added a Canon 5DC with 12.7 MP. The filesize here is really small (12-15MB). Small correction cropping is still possible but heavier cropping is not adviced, meaning you have to be a bit more determined when you take the photo which is o.k. .... Image qualitiy wise, I do the love the raw photos coming from the 5DC better. Richer colour, nicer rendering. I hardly have to do anything to the files in post whilst with the EOS R it's always a bit more tweeking. Some say that the lesser and bigger pixels on the 5DC sensor account for better colour seperation. Not sure if that is true but there surely is something different with the photos coming from that camera.
Great, informative video! Thank you for making it.
I have a 24 and 42 MP camera. On the high resolution camera I love the possibility to crop the image and do large prints without thinking about resolution. Other then that, 24 is enough. For the larger files you not only need more storage, but the processing is much more demanding for your computer.
Tremendous video. Thank you
This was a good, clear, discussion of real-world resolution requirements. One point about resolution needs for large prints: the human eye can only resolve down to one radian (1/60 of a degree). For reference, in a normal, well-designed, movie theater, if you sit in the middle row, the screen will take up approximately 30 degrees of your horizontal field of vision--an image which hardly looks small. Given that our eyes can't see any detail smaller than one radian, once the resolution reaches 1800 (30 X 60) horizontal pixels it will appear perfectly clear on that movie screen; adding more pixels won't make it any clearer to us. Now, if we're talking about large prints, virtually nobody looks at a print where it occupies more than twice the field of vision that one gets in the movie seat just mentioned; an image at that relative scale would require 3600 horizontal pixels and 2400 vertical pixels, or 8.6 megapixels.
Minor correction: Of course you meant to name an angular resolution of one arc minute, not one radian.
@@brygenon My bad!
Thank you !
Thank you David for such an insightful talk on the most talked about topic in digital photography.
It depends on your requirements. The latest high megapixal cameras, need correspondingly better optics, to get the advantages. I use a 60mp camera. On large banners 4m x 1.5m you can definitely see the benefits.
One of the best videos on here about this topic… TH-cam needed something like this … I recall looking that info before my upgrade and never found it !!!
Thank you..gud info
Another consideration related to file size *may* be your computer. With an older machine, trying to process 50-60mp RAW files in Lightroom might test your patience. In other words, a high megapixel camera might be even more expensive than you think if you have to upgrade your computer hardware along with it.
I had started with kodak cx with 2MP and a Nikon D70 with 6MP.
I do fashion and beauty photography for a living and most of the assignments are shot with 50 or 100MP Hasselblad or 47MP Leicas. Usually the client requests a minimum of 7000 pixels on the long side. That results in approx. 40MP. It gives them manouverability for print. The image editor however, is more concerned with bit depth. They usually love the 16bit of a Hasselblad. It provides for easier color editing. Having said that, 20 years ago we’d publish 12MB images with a bit depth of 8 or 10. Still beautiful images.
For personal work, I use a Q2 or M11 when I really go out and take time to create deliberate images. For travelling, casual shooting and flexibility my absolute fav camera is the Lumix G9 with the Leica 12-60. ‘Only’ 20MP, but an absolute gem, even today. It handles like a dream and for image quality the lens makes all the difference. My advice? Buy what you’re able and willing to carry.
Thank you Mate well said.
You mentioned storage for higher MP images, but one thing I didn't hear is that you also need a faster computer in order to process your images. A computer that is perfectly capable of processing 20MP images may be as slow as molasses trying to process a 40, 60 or 100MP image file. Bottom line, having more than what you need is good, but you have to balance your needs with cost. If 20MP covers 95 to 99% of my needs, I rather stick to that and either rent for the 1% times when I need the much larger files. Better yet, I'll get a 20MP camera that has a High Res mode capable of producing those higher resolution images when needed.
Great video. Thank you for the logical approach to an often hyped up subject.
Also, how good are the lenses used? Older lenses won’t benefit from high mp cameras.
Well done, David! I was _just_ looking seriously at a low-shutter-count Nikon D850, having a bit of Pixel-Envy from my EXCELLENT OM-1 camera system; plus wanting to take advantage of the 10 Nikon lenses I already have. Although I'm presently out-bid on the Nikon, I VERY happy with my OM-1 System for Weddings. Thoughts?
Related to this question. Sensor size. Some people a sensor size snobs. “I’d never shot with anything less than a full frame sensor.”
I am an amateur and shoot street photography. I don’t need bokeh. As a matter of fact, I shoot around f5.6-8. I shoot in the day so don’t need great low light performance. How much difference can I see between M43, APSC, and FF sensors? Forget medium format.

In good light at low ISO, you will be hard pressed to see a difference.
Great information! And in one take! Nice job!
lol thanks! I usually do these in one pass, although I can cut when I’ve got b-roll / images on screen. 😜
A great video that can explain the concepts clearly within such a short time. Very well done! Great job David!
Thanks!
Once upon a time, I did some calculations based on something I came across saying people can resolve 180ppi at 1M viewing distance, combined with how far away from a large print I tended to stand in order to scrutinize the amount of detail I might want to pack into that size of print and came up with 54MP as my ideal for being able to print large and lean-in for seeing details - the assumption being that if the print were larger that I would probably want the same amount of detail and so would be standing proportionately further back.
In 2005 I bought my first digital camera, a Olympus E-300 , 8 mp.
Still using it today.
I also bought a E-330 ,7.5 mp and a E-410 ,10 mp.
For my kind of photography those megapixels are more than enough.
So i still using them for my everyday cameras.
I also bought a Sony with 20 mp, it's the first camera I regret buying.
Image quality of the Olympus cameras is way better than the Sony.
David I LOVE your videos!! Short, concise, to the point. And as an fyi I bought my first SLR, a Minolta SRT101 as a three lens kit at Adorama in 1973!!!!!
Wow! What was the price back then?
Thank you David for a great technical explanation. I would like to hear your thoughts on some of the new upscaling programs out there.
45.6 megapixels for me I like to crop! Best all a rounder for me Nikon Z8 Love it The price was right.
I'd say this depends on how hard you expect to crop.
I’m happy with my old D810. Last year I could have used a D850 with 10 MP more, so I’ll purchase that camera at some point, but Topaz Megapixel AI did the job, though, of course, scaling is always visible at some point. The sewn seams in a car‘s leather seats and the imprinted pattern looked a bit fake, so nothing beats real Megapixels. But 100 or 150 MP are a bit excessive, though I can imagine, having demanding clients, they could come in handy for certain work with low shooting frequency.
Most hobby photographers I know scoff at my cameras though. „Why don’t you have a mirrorless Z666?“ „Because it doesn’t make me a dime more“. Rent if you really, really need huge format shots and let the client pay for it
The average consumer can't be bothered to learn the exposure triangle and offsets it by buying for more megapixels. The best thing you can do for image clarity and definition is to learn the technical aspect of photography and perhaps upgrade your lenses before spending money on a new body.
My experience of my Nikon D810 was that the higher resolution managed to resolve camera shake better and getting a sharp photo was hard, so I sold it.
In order to project at 300 DPI on the world's largest movie screen you would need 242,114 megapixels, rounded up. Any more than that would be a waste. I hope that answers the question once and for all.
Thank you David ...You are a leading asset !!
Wow, that was a lot of information! Thank you.
Simply Excelente! Awesome! ❤
That .... was an excellent explanation of the main issues ..... and it was short enough to keep me engaged. All the facts in one place. This should be a reference guide for anyone wanting to splash the cash. Thank you ... much enjoyed and appreciated.
David is always a pleasure to watch your videos please keep making them
