Does not low f number and lens sweet spot contradict each other ? Most lenses have sweet spot around 5.6 to 8 and in order to get more back ground blur we have to go below 2. That will decrease the imge quality in a picture ???
In general yes. But there are a few factors that we have to take into account. The first is that really high-end lenses are almost as sharp wide open, as they are at their sweetspot. Second, the center is almost always pretty sharp, most of the quality loss happens in corners that are not really relevant for portraits (because they would contain only the background), and third there is an effect called perceived sharpness (sharpness contrast) - so if you blur the background to separate your subject, it appears sharper than it would if it had a sharper background.
I like your explanation. I knew about going close and zooming in, and wide aperture. I never thought of background distance , I sort of knew about sensor size but you have laid it out really clearly.
Thank you for your feedback. With Bokeh the problem is: the smaller the image gets (e.g. on a smartphone side by side, or on the back of your camera) the less visible the difference is. I usually try to provide links to my website for side by side comparison. Maybe I should set one up and repeat the video 🤔😉
Excellent example showing that "focal length beats distance to subject" in term of background blur. I'd be happy to understand why, since the DoF of a 200mm @ f4 & 20 meters distance is the same as the DoF of a 100mm @ f4 & 10 meters distance.
Thank you! That's a good question. Without using the maths, but trying to think about a hermeneutic explanation, I would say it might have to do with you basically zooming in on the background when using a longer focal length, while the distance subject-background stays the same.
Wow . . . Great work, well explained, well thought-out, and incredibly clear and accurate. I'm only *sort of* regretting my Panasonic G85 purchase, but for budgetary reasons, I'm still happy with it (I got the camera, 2 lenses, and some other stuff like a camera bag, an SD card, some filters, etc etc for $700 -- still can't find a similar deal anywhere online). Now I'm just going to keep watching your videos to learn (more) how to maximize the capabilities of the camera I have (as well as *my* ability to use said camera . . . ) Thanks for all the great work!!!!
Thanks for your feedback, Mitchell. Don’t forget that a cam with a smaller sensor also has some advantages 😉. Enjoy your camera and thanks for watching 🙏
Very much informative and practical. Thanks for sharing things in this way. We see lots of videos where the theory is prioritized only. But you have smoothly mixed the theory with practice. Hope to see more videos like this. Kindly make a video regarding the relationship between Aperture and focal distance.
Glad to hear it was helpful, Edward. What do you mean with focal distance? The depth of focus or the distance from camera to the subject you are focussing on?
@@wolfamri Let me give you an example. If I take a shot at 18 mm, F/4 then will it focus more area than another shot at 35mm, F/4? If it does, how? why the wide angle lense does provide wider aperture like 2.8 if narrow aperture is needed for landscape? can I take a great landscape using 2.8 aperture?? This is kind of confusing to me.
I’ve been binge watching you since yesterday lol. I love all of your content. Can you please tell me what camera and lens or lenses were used to do your talking shots outside in front of the greenery? The bokeh is just amazing and the shots are so crisp.. I know your are far from the trees outside but the lens is just amazing.
Thanks for watching 🙏😉. I’m afraid I cannot really tell. Looking at the angle of view, I’d say the 55mm when the 85mm was in the shot, and 85mm when it wasn’t. I hope that makes sense 😉.
Hi there. It was the DJI Ronin S. But nowadays there are even smaller and lighter gimbals on the market. I prefer small and light fur easy packing and fast use 😉
Thank you 🤗. It’s totally normal to not learn by watching a video once. That didn’t work back in school either (at least not for me 😁😉). Repeating is the key to learning. As adults we all seem to forget that.
Thank you for this thorough explanation! Basically, it's distance and light over gear every time. I've been having a hard time because i have a crop sensor, which confused me.
Hello! Nice video! Can you please let me know with what camera & lens the video is made ? Specifically the first seconds. I really like how you stand out of the background
sibghatullah, I‘m afraid tgat is going to be difficult. I‘m preparing a macro solution comparison for the next few weeks, that should help you on the macro side of things. For the telephoto side. you need to search for a used 70-300mm or so.
Very good explained. But I have a question. If i want to shoot a music video. if the performing band is in front of me and distributed in a area within 2 or 3 meter to each others. Then if I want to have all the band not blured, I will have to choose a wide angle lens (e.g. 16 mm), choose a high aperture and try to place my camera so close to them as I can. Correct?
Thank you! Yes, a wider lens will create a bigger depth of focus. But very often the room is a more limiting factor. So you may have to choose a very wide lens anyway. Plus: the sensor size matters too ;)
thanks!@@wolfamri i was more wondering why tho? i understand that thats the case. like....weve manually increased the distance to subject by walking back....but then shortened focal lengtrh with the zoom.....so why it makes a difference? no probs 🙂
@@MrRoFella It’s really just a question of physics. You can theoretically calculate the background blur. And in that equation, focal length plays a bigger role than subject distance. The answer is really just that boring 😬.
Let me give you my opinion 😉: people talking about toneh don't like to follow trends and don't like to be told what to do. So they rather tell others what to do. It's a bit of a paradox 😉. I personally like what I like and accept that others have a different opinion. It's the same in many other fields of photography, like brand fights or the crazy fight for BBF Vs half pressing the shutter. There is no right or wrong 😉.
I do expect that to become better and better, but it's still rather random and not there yet. But then again it's all personal preference. Anything that satisfies you is easily good enough. You don't have to listen to anyone else but your own feelings.
@@wolfamri Question: I am currently using an a6300 but want to upgrade to a full frame camera. I'm thinking of getting an A7rii (42mp)since when paired with an apsc lens I can still get (20mp) pictures. That way I don't have to immediately replace all my lenses with FF lenses. I realize I will still have the apsc crop but this will allow me to buy FF lenses at my convenience. Thoughts?
You'll get 17,8mp from the a7rII. The question is what you need. I own the a7rII and a7III. I mostly shoot with the a7III because I need the faster focus and the faster frame rate more than the high resolution.
I’m afraid that’s not easy to answer 😉 That depends on the focal length of the f/1.4 lens and the min aperture of the 200mm. Did you have a look at my comparison tool/video?
@@wolfamri yes I did 200mm bokeh looks better than f1.4 if the subject is close and half for full size f1.4 bokeh looks better and 200mm doesn't seems better as it was in half potrait so it's hard to conclude which is best
I would like a tee-shirt but I can't find your link for it. Please make it easy enough for all of us to get too in case we have any money burning a hole in our pockets... You could also do a tee shirt with a crocodile (at least the head of the crocodile) and use the same saying as the snake, Smile, I may snap. Or "Smile, I have an intendancy to snap."

Actually sensor size has little to no influence on Blurry background. It's not related to the camera, but to the lens, so, if you shoot an 85mm lens on a Full Frame or on a Micro 43 sensor the blurryness of the frame is the same. which is obvious: the same lens has the same bokeh. What changes is the framing, and that's because you need, for example, a 42mm on a M43 sensor to get the same framing of a Full frame 80mm and you also get a less blurry background, as you are shooting on a lens that has half the focal length.
Maybe it helps to think in systems rather than sensor sizes/focal length only because theoretically if you get the 42mm with a much wider aperture, than the full frame lens, you can still get the same blur. But these are not available on M43, so it kinda has to do with camera/sensor again.
I'd disagree on the sensor size being a factor. The reason the blur is less on the smaller sensor is because you backed up (distance to subject is increased). The cell phone can't be compared here because it's digitally converted to 52mm. In reality the cell phone lens is 7mm. Sensor size has no effect on bokeh.
It is what is. Similar composition, different sensor, less bokeh on the crop in real photography. That’s what counts for the photographer, rather than maths 🤷♂️.
Lucy, theoretically you are right, but I’m afraid practically not. Photography is about composition than maths and when you compare the roughly same composition, sensor size is relevant. Just take a look at smartphones 😉.
1:55 "Let me compare F1.8 which is an aperture you will only find in so-called prime lenses..." Uh ... I own two F1.8 zoom lenses. The Sigma 18-35 and 50-100.
Those two Sigma lenses are from the DC line, which means that they are made for aps-c cameras. So, you have to apply the crop factor to the f number in order to have the same amount of light as in a full frame camera. Your f/1.8 zoom would be equivalent to a f/2.7 prime lens in a 35mm camera. As far as I know there is no zoom below f/2.
Oh well, there’s lots of things that would need to be explained. IMO “Me first” (America first, Britain first, Austria first,…) is the reason to almost every crisis on this planet. Togetherness and caring for others and our planet would solve it all.
I definitely like your videos and I understand, that presenting this subject the way you do is easy for beginners. Unfortunately, there's too many misconceptions in this specific videos about depth of field, how it actually works and which factors DIRECTLY influence the depth of field and the out of focus look. I highly recommend you watch this video: th-cam.com/video/1bzHn2cKwLI/w-d-xo.html
Thank you for your feedback. It's tough to find a balance between scientifically perfectly correct explanation, things that are actually happening during practical photography and packing it in a way that beginners will really understand and be able to use it. I do have a heart for science and maths, for example if you look at my aperture numbers explained video. But in my experience that is confusing people more than it helps. Maybe once I have finished my new photography course, I will start a new channel "the science behind photography".
"If life gets blurry adjust your focus" good one...
