It will be close, comparative views at Camera decision with III copy and pasted over II at 50% opacity on left.

The top dials seem to have moved very slightly. but everything else is very close.

I have the impression, this is just a slight perspective shift resulting from two different photos taken.

Putting myself in Canon's product management shoes, I would try to utilise the same body tooling + parts when the design change and upgrades are all internal. So I conclude the camera body is very likely to fit in all existing R6 II underwater housings in the market.

Let's wait and see for the confirmation.

Agree it has a good chance of working - we'll wait and see what the housing makers do - maybe a R6 II user will take a chance and try a MkIII in their housing for us?

I made the same comparison with cameradecision visuals and apart for the on/off switch also saw that the joystick is a bit more sticking out.

I am going to check whether this prevents any movement and will keep you updated.

I might be an early adopter as these were the specs I was expecting from my next camera when I was in the market. However, I settled with the R6 II as there was no such offering.

Additionally, I still believe that the R6 II is an excellent camera even though the R6 III is out.

The new x-sync speed is a real treat and makes me consider it as another camera body next to R6II. The additional megapixel count raises the attractiveness even more.

For photography, it is basically the same camera except for the 32.5 MP sensor upgrade where you can get more sharpness and more cropping ability.

I think there is a misunderstanding with the sync speed of the camera and I had a look at the detailed specs. The x-sync speed of 1/320 applies for cropped resolution which is not very useful:

This is the same for R6 II for full frame resolution.

There is a slight banding issue visible when EFCS is used at 1/250 with my YS-D3s. So, I would be careful when relying on maximum specs given. The number 9 and 10 footnotes in the screenshot also mention that these speeds are only compatible with Canon’s own flashes.

I usually shoot at 1/200 and use 1 or 2 stop ND filters internally depending on the scenario if I really want to block ambient light. This results in the equivalent exposure of 1/400 and 1/800 of light stopping speed and would also recommend this.
