Canon EOS R6 Mark II Sensor Measurements at PhotonsToPhotos

Thanks for posting Bill.

Where the electronic shutter starts to have a similar PDR ot the mechanical, at around the 8 point is this similar to other Canon cameras? (Sorry I have some network issue with your site at the minute so couldn't check).

The effect of Electronic Shutter (ES) varies depending on the camera model so you'll have to check that out yourself. Hopefully you network issues will resolve. I'm not aware of any issues at the PhotonsToPhotos.net end of things.

Bill you are the man. Thank you for all that you do. Photonstophotos is such a great resource.

The dynamic range of the R6ii looks solid and truly competitive with Sony offerings.

Can you explain whether the "triangle down - noise reduction" markers for sub 3200 ISOs is a bad thing?

I see that the Sony A74 for example... has similar values but only circles.

Does this mean the Canon sensor is sacrificing some detail to hit these dynamic range figures?

My untechnical mind is surprised there would be noise reduction going on at iso 100.

Noise Reduction (NR) at low ISO settings has become more common with certain brands in recent years. NR does result is some loss of detail but I have no truly objective way of measuring that. I'm working on it. Personally I would prefer to have complete control over how I apply NR so I would prefer that I could disable this behavior. Strangely enough it is not applied when Electronic Shutter (ES) is invoked. (As I was writing this I realized that my software wrongly put the triangles on the ES data and I have just fixed that.)

One way to judge the amount is to look at the energy spectra.

R6 Mark II

R6

R6 Mark II (ES)

The stronger the NR the deeper the dip. Flat is no NR.

Great info as usual. Interestingly both old and new R6 exhibit similar measurement, ie. DR is reduced using ES at the lower ISO.

Why is this so? Fuji, Olympus, Sony, Nikon, etc don't have such gaps when using ES vs MS.

Any ES measurement for the R10 and R7?

Thanks.

I believe the electronic shutter is lower bit (12?) files and therefore lower dynamic range    — could be wrong

Yep it's probably due to Canon's ES still being limited to 12 bit read-out. It's common in all R bodies.

I believe the ES of the R3 is 14 bit

Yep, I think this is the only exception.

yep, that's one of the appeals of the R3 above the R6 (II), plus the stacked sensor for those that shoot fast movement

I thought the original EOS R gives 14 bits in ES. It certainly gives 30 second exposures in ES rather than the ½ second maximum of the R5/6.

That is also 12-bit, I don't recall the maximum shutter time myself but with your info I don't know why those systems are different.

We didn'took at the R3 to closely due to its resolution but the information from the analysis Bill has provided shows a different pattern to other R cameras operating in ES.

that e-shutter for DR sucks on R6II

Even my M6II with e-shutter uses 14 bit and has better DR

maybe at base iso, but it's not that great to be honest. Rather have that R6 (II) since that still gives you the option to use max dr with a mechanical shutter
