Thank you math for the great presentation as always. I realized after taking several multi-shots, I need strong tripod and fast computer.
A very insightful analysis again, thank you so much!
Excellent video and lots of interesting technical info. Thank you !
Best SL2 series review on TH-cam so far! After update 2.0 there’s still some hot pixels issue randomly occurring when you do for instance 30s when iso is above 800. And looking for some SL lens pros and cons video from you too!
I had same issue - I turned on long exposure noise reduction in settings and it made it better
Maybe it's just me, but for the first image, the single shot looked sharper.
If there is even the slightest bit of motion in a photo it will be blurry in high res mode as it stitches together multiple images. Could be okay for architecture or something but for landscape its pretty useless to me. I haven't used a Leica but its much the same as the Panasonic which I have used.
I saw the same, but if you print it (large format), you will see the difference!
Agreed, very obviously so. He had the tripod up at full height with column extended, rookie mistake for this sort of thing.
Clear and interesting as all ways
I would agree on your conclusions as regards resolution. But have you tested noise and dynamic range, especially if you pull dark areas. That results visibly much better. You should make a test on that.
Love your videos mate 🍻
thx
Great video! I don't think multishot is necessarily an essential feature but I do believe it will be used a lot by fine art landscape photographers who really are the only ones who need extreme resolution in a compact form-factor. Keep up the great informative videos!
My thoughts exactly, I leave on Wednesday for Yellowstone/Grand Teton and I'll be using it!
You da man.....Love this channel...
Thanks again! New SL2-user.
Congrats :) You will love your SL2 in no time, I am sure.
Which tripod do you use for the SL2?
Thanks, this is a really useful video.
If one is going to stress the resolution limit of the camera, the diffraction limit also needs to be taken into account.
For the Leica SL2 native resolution, resolution becomes diffraction limited just under f/11.
However, for the multi shot mode the image will become diffraction limited between f/4 and f/5.6.
So in your heavy "macro" crop example at f/8.0, the multi-shot mode is really just taking a high-pixel resolution image of an optical image that is diffraction-blurred.
It would be really interesting to see a similar test taken at f/4.
I have used the multi-shot mode for landscapes & didn't take into account this diffraction limitation, so the results weren't really worth it.
I've also noticed strange, pixel-shifting artefact deep in the image, which I suspect is microscopic camera shake from longer exposures in low-light, on a slightly windy morning.
So multi-shot is an interesting mode but the shooting conditions need to be perfect and the diffraction limitation becomes quite dominant.
This diffraction limitation is one way in which a medium format camera would significantly increase the technical envelope for photography, achieving similar resolution with fatter pixels.
I think diffraction is, t worst, unaffected by multishot. This isn't the first camera to have this feature, Olympus has had it for years, my Lumix G9 and S1R have it. I only remember one reviewer commenting on it, and he was positive.
In the first image from the bridge was a moving train in the background while you take the multishot image. What happens with the train in the final image?
Great video as always. Did you ever confirm, if leaving the 'Motion artifacts correction - off', have any sharpness effect ? Thanks,
Thanks Carlos, I so far always had Motion Artefacts Correction on, will look into it.
I bought a Lumix S1R for its high resolution mode. I use Canon TS-E lenses, and I want the ability to crop. If I use a TS-E 17, I should be able to get both the 17mm and 24mm perspectives from the same shot. Maybe portrait and landscape orientation from the same shot. Or even add dutch tilt in post.
46 Mp is clearly sharper and contrast at 06:28 seconds , if you notice that Board U63
sharpening settings at 47mp and 187mp hve to be different.
It also depends on how LR renders previews or zoomed-out images on your screen. A highres image can have an unsharp look, but when zoomed in to 1:1, show more detail. That said, I'm not too impressed by the 187MP image I saw in the video.
I don't judge photographic sharpness in TH-cam videos shown on my computer monitor even at 4K. I don't see how it's valid to do so.
Fantastic learning moment !!
Thank you so much !
Do you know some other brands that offer this multishot option ?
I work with Fujifilm X-H1 and I'm searching for my next high-res camera (for extreme macro shots).
Take good care of you !
Colin
Olympus in the OM-D E-M1 Mark II and later. Some E-M5, possibly Mk III and later.
Panasonic Lumix G9, GH6 and all Lumix S. The S1R matches this Leica.
Hi mathphotographer!
If you see this message, can you consider doing a comparison between your SL2 and Sony a7Riv?
I think it is a good idea to compare the image quality of Single Shot and Mulit-Shot for these 2 cameras. It is a lot harder financially for most people to buy into the PhaseOne system. So while it would be interesting to watch, it is also less practical. But a comparison between SL2 and a7Riv will definitely be something useful for many viewers, including myself.
Thank you!
That said, I appreciate your videos and I'm addicted to them. I, too, shoot with an SL2. I have a love/hate relationship with it. I love the image quality; I hate the slow buffer speed. When tethered in studio it isn't an issue (produces images equal to my Hasselblad H5D); however, when working in the "real world" it becomes problematic. And frustrating. I still need to stash my old Nikon D4 near by when shooting PJ work....Just in case. And that "just-in-case" scenario happens a lot.........Am still a Leica loyalist; they have best lenses...........
I’m sill waiting for the Fuji GFX100 update for 400MP Tiltshift.
Thanks Math!
Do you think you could use the Multi-shot on an Astro scene?
For the Leica SL2's multi-shot mode, the exposure time is limited to 1 sec.
In astrophotography, where the need to gather light is the dominant consideration, one would need to take a hundred times more images to stack in order to get a similar overall exposure.
At that point, the heat noise, tracker jarring, camera shake and atmospheric noise all become significant limits on resolution.
I've tried multi-shot for wide-sky astrophotography just to see what happened and came to the conclusion that the exposure time limit meant it was more bother than it was worth.
However, if someone was prepared to put the effort in, the heavy crop reserve might make it worthwhile for deep sky astrophotography.
In that case, high-end active tracking would really be mandatory.
@@sophrapsune That 1sec limit is what I was looking for. Applies to Lumix S1 series too, though the S5 is better.
100% is the only comparison that matters.
Ich platziere hier nun einfach meine Frage: Bei meiner Leica Q2 verändert sich die Schärfentiefe auch im Sucherbild, wenn ich abblende, ohne dass ich irgendwas eingestellt habe. Ebenso bei der Sony 7 III. Bei der SL 2 tut sich nichts, da sehe ich im Sucher auch beim Abblenden immer nur das, was bei Offenblende scharf ist, somit keine entsprechende Vorschau der Schärfentiefe durch das Abblenden. Daran hat sich auch nach dem Update nichts verändert. Das kann doch eigentlich nicht sein. Kann ich da was einstellen? Herzliche Grüße Jan
Muss ich näher anschauen, melde mich, falls es eine passende Einstellung gibt.
I can’t think of any reason the SL can’t get the same upgrade, even if it’s 2,3,or 4 combined. Although I see no real advantage in the multi shot. As always, very nice work.
It needs the IBIS which SL doesn't have
oscarchong not really, you might not get those 2-4 pixels around the borders in high res but you’ll never see it.
The Leica SL doesn't have the IBIS hardware that allows the multi-shot mode.
The IBIS moves the sensor in sub-pixel shifts that allows the increased imaging resolution.
@William Inbody@@sophrapsune But you can do high-res multi shot with any camera with and without IBIS. You have to make some handheld shots in Burst Mode, scale them up to your target resolution up to 2x per axis and stack them together in your photo editor. auto-align matches the pictures pixel perfect, but because of the shake of your hand every Photo is slightly shiftet at sub-pixel level. Of course the random movement of your hand isn´t as accurate as an actual pixel-shift feature, so you have to take more pictures with this method to get a significant increase in detail. 8-15 pictures gives good results in general. Noise will be also greatly reduced with this method.
Thanks you. Very good presentation. I have an Olympus EM5 MKii of 2015 vintage that employs this technique with a resulting file of about 60 MP in RAW. The technique is only and only useful for absolutely still objects such as those in a studio product shot, it is of absolutely no use in any shot that has moving objects nor can it be used for landscape shots if plants and shrubs move in the wind. As you stated the requirements for the rigidity of the camera and tripod can not be under estimated. This technique relies on the sensor anti vibration mechanism of the camera to shift the sensor exactly one pixel in any direction. So for this to work the movement of the camera on the tripod must be less than the dimensions of a single pixel otherwise beautiful artifacts are the result. TBH I really don't know what the processing requirements for a 180+ MP file are like particularly if the new AI enabled software are used. This technique is nothing new BTW. I believe it is based on a technique called ' Drizzle ' which was developed by NASA when they found out that the deep field camera sensor of the HST was under sampling. I often performed Drizzle when doing deep space imaging to combat the under sampling of my imaging telescope/ sensor. To do Drizzle the computer controlled mount has to perform what is known as a ' Dither ' between the subs ( shots in daytime imaging ). Dither is the random shifting of the imaging telescope/sensor of order of a few pixels between subs. Drizzle results in huge files with incredible resolution if the sky conditions are right. I guess someone in Olympus/Panasonic/ Leica eventually caught up with deep sky imaging techniques.
Olympus technology has advanced since then. Several models can do it hand-held for 50 megapixels.
Leica SL2 VS Canon R5 is needed 😁
salduaij structurally from what I have seen the Canon doesn’t even compete with the Leica.
Andrew Porfyri i agree with you but was released and reviewed was not the final production version 😁.
for how long does one battery last? m10 is to low. thx
several hundreds of shots; but I always have spare batteries with me
My camera is 16 megapixels. Cheers
Just a quick note: viewers here no doubt appreciate the well-constructed videos on various high-end photography-related equipment. However, there is one glaring consistent weakness to some of these analyses comparing different systems: the issue of diffraction. For example, the video comparing the Phase One IQ4 to the Leica SL2 multi-shot was conducted at apertures of F11.
In this video, you again stop down the apertures for the comparison to F/11. The single-shot SL2 here shouldn't be stopped down more than F8 or even F5.6, and the multi-shot SL2 here shouldn't be stopped down more than F4 (and theoretically even F2). In brief, you need two pixels to resolve a "detail". The blur diameters, which you do not want to exceed with diffraction, here are 8.5 and 4.3 microns for the single-shot SL2 and multi-shot SL2, respectively. From these diameters, you get the theoretical F-stops noted here for maximum resolution.
I even found that 47 is more sharp in than multishot.....
Not always but sometimes. Really depends on the scene and the conditions. I had some samples, not many but a few, where your comment is spot-on.
I disagree There is a noticeable difference. Look closely at the edges of all of the objects. They are sharper around the edges in the multi-shot. So, when looking at both images comparatively, the multi-shot has greater sharpness as a completed image than the single shot.
I was supposed to see a bigger difference...

Multi shot is a gimmick. Unless you’re using it for still life it’s a complete and utter waste of time. I tested the feature on the H6D 400 using the same technology and its NOT designed for outdoor usage as you’re doing where unavoidable ghosting from the different colour layers makes it useless for moving subjects including leaves on trees and even birds flying through the sky.
You should test on cameras not made by H. They aren't all the same.
