One comment about all the talk of an R6 using the same sensor as the 1Dx III. Of course we have no idea whether that will be the case or not, but even if it is, it sounds to me, from reading Canon's white paper on the 1DxIII and from reviews and samples online, most of the "magic" come from the processing in the camera. The increased low light capability seems to mostly be in Canon's treatment of jpgs. So, even if they used the exact same sensor, it is highly unlikely that an R6 would have the same sophisticated processing algorithms that are applied to the 1Dx III.
Absolutely - and the iDX III will have multiple digics involved in that processing, as opposed to the R6's one. It may well be the same sensor, but this shows up the limited role sensors play in camera performance in 2020.
A couple of random notes on this:
- The 1DX3 has a single Digic X, and that's basically where the camera's horsepower comes from. Seems like any additional chips are more about PDAF AF/iTR/metering, etc--that's all stuff that's
DSLR specific.
- At the speeds stated for the R6, I'd be surprised if they didn't use a variant of the Digic X. My personal impression is that a lot of canon's mirrorless performance will hinge on this chip's architect. I'll grant that Digic X is probably more of a platform than a specific chip, and it might not be identical to the 1DX3, but folks--they're not going to stuff a Digic 8 in this.
- When talking about IQ, I was referring to RAW DR performance. Digic shouldn't matter here.
- If (and yea, it's a big if) they are using the same sensor, I'd expect pretty much identical images. Canon has no need to protect the IQ of the 1DX3, that's not the name of the game for that camera.
I'm going off of the rumors here, but I find it unfathomable that canon would create a second FF 20mp chip suitable for ILC cameras.
