Multishot is not offered when using APS-C lenses right now. Did write to Leica on this. ISO seems to be max to 3200 right now. Short exposure times seem to be key for handheld Multishot working and quality. Some images show artifacts at extreme corners. Anyway, this is all version 1.0 of Multishot. I am sure, Leica will improve with further firmware updates. Already now, I am impressed by a 96 MP hand held Pixel Shift! This was always the case. why would you want to reduce the resolution to 10MP before increasing it back up to Multishot? Link to post Share on other sites More sharing options...

Photoworks Posted January 18 Share #42 Posted January 18 Stefan Daniel said that M lenses are to be used on M and SL cameras everything else nicht empfehlenswert also over the years, the microlens cover glass has been moved away from the sensor to reduce the effect of sharp sensor dust. 6bit Coding was added to the M lenses to get more consistent colors between the M lenses on Leica Cameras Link to post Share on other sites More sharing options...

Well, Multishot is just a pixel shift. So, a pixel shift should work with the APS-C crop too IMO. Sure, you do not get 96 MP but more than the 10 MP IMO.

BernardC Posted January 18 Share #44 Posted January 18 8 hours ago, LD_50 said: The thickness of the cover glass impacts the light’s path to the sensor. It does matter and if it is different for Leica and Panasonic and Sigma, there would be a measurable impact on performance of L-mount lenses on those cameras. Ideally it would be exactly the same across cameras so that the lenses designed for one camera would work equally well on another. I don’t expect anyone here will know for sure, but I also don’t think the physics are debatable. Optimizing for M lenses seems to require a different glass thickness in combination with a micro-lens array to properly orient the ray angle from lens to sensor. Knowing this, Leica would presumably design their L-mount lenses to align with the SL sensor. L-Mount lenses (and all digital-era lenses) are designed to be more telecentric than film-era designs. A slight difference in cover glass thickness won't make a material difference with this type of design, because light hits the cover glass at roughly the same angle throughout the image field. The fact that Leica's L-Mount bodies work better with some M lenses does not mean that they will be worse with near-telecentric lenses. 2 Link to post Share on other sites More sharing options...

Yes, the corners (and EXIF data) are the only changes one sees when disabling 6-bit coding on a lens. 1 Link to post Share on other sites More sharing options...

Something must have been lost in translation. I'm sure he said "evenly distributed" or something similar. This is such a well-known fact, ever since the first M8. Leica lenses always strove for consistent colour of course, since they were used on film. Link to post Share on other sites More sharing options...
mpauliks Posted January 18 Share #51 Posted January 18 Does someone have some tips & tricks for best way to capture handheld multishots so far? With wideangel it works pretty fine for me. But already with 50mm it really gets hard for me. Shortening exposure time seems to me not always the best way. Please share what works fine for you with handheld multishot Link to post Share on other sites More sharing options...

It seems that the stabilizer is off for handheld multi-shot, which causes movement between the shots to be too much when shooting handheld with longer lenses. 2 Link to post Share on other sites More sharing options...

I guess it has to, although I am not into the technical Multishot details. How otherwise to ensure that the scene is absolutely fixed when multiple shots are taken, each shifting the sensor a tiny bit (one pixel) in the two image directions? This also means that the camera must be held absolutely still (plus that the scene must be approximately frozen) for Multishot to properly work. 1 Link to post Share on other sites More sharing options...

Yes with 24-90 and its lens stabilizer, I can go pretty easy for 35 and with some trials for 50 Did put ISO fix to 3200, so max. And used widest open aperture in order to get shortest exposure time possible! Thank you again Did try inhouse so far. I guess at daylight it might be more easy Link to post Share on other sites More sharing options...

AFAIK, only tripod multishots use pixel shift and require stabilization to be off. Handheld multishots (superresolution) require slight camera body movement, and stabilization can be turned on. That said, handheld multishot should work with stabilization turned off as well. 3 Link to post Share on other sites More sharing options...

I see, or possibly see... So some sort of in-body image alignment is part of the magic, then (?). Well, as long as it works, things are good (waiting for the SL3-S, SL2-S was sold some time ago). 1 Link to post Share on other sites More sharing options...

Because of that limitation, I consider the handheld multishot broken. Can anyone with S5 II confirm that handheld multishot works with longer focal lengths?
