Canon officially announces the Canon EOS R3

Made a list of the things we're finding from the reviews that we didn't know from the rumors and leaked specs. It's a growing list...

Overall, a very solid camera for high-speed low-light photography. For me the highlights are the following:

1) 1/64000 top shutter speed with electronic shutter
2) full 14 bit files with electronic shutter at 30 fps
3) electronic shutter at three speeds of continuous shooting of 3, 15, 30 fps
4) solid high ISO noise performance
5) Assignable Q menu
6) More flexible customization
7) built-in GPS
8) Weighs almost 1 lb lighter than the 1Dx Mk3 and about 200 gram lighter than a R5 with the vertical grip attached.
9) Better low-light AF than the 1Dx Mk3.

A comprehensive list, thanks for sharing!

I am so excited about the customizable Q menu!
Been hopping between the different reviews. Would you mind sharing where you saw this?

When I first saw the Eye Control part of the "Officially Introducing..." video, I initially thought the man was wearing a clear face shield with a heads-up display, and that this contraption would be required to use the Eye AF! Glad that's not the case! I immediately pictured myself on the sidelines looking like some techy photo nerd getting unwanted attention (enough of that already).

On a second note, despite the new "adapter," the R3 can natively use any hotshoe mounted flash like all previous cameras before it.

The adapter exists to adapt the weathersealing to a weathersealed speedlite like the EL-1 and 600EX-RT. Because of the new, bigger shoe, the rubber gasket of those flashes doesn't fix to the shoe like it does on previous cameras. The $40 adapter is only for those who want to continue to have full weather sealing with these flashes.

I still bought one for the rare event I am shooting in the rain and need a flash. I'm interested to know if the weatherseal is "complete" with just the adapter mounted, as the EOS-1 series never required a cover on the hotshoe to complete the seal. If so, I will probably leave the adapter on all the time.

I missed that bit. I was presuming the gasket blocked proper mounting to the new shoe. Did some video reviewer demonstrate mounting a 600EX or EL-1 on the R3 and have it fire? If it’s only the weather sealing, that’s great.

Looks like the devil was in the details on this one....the 'underwhelming' press release (as declared by some on the internet) that came out last night didn't cover a lot of the important specs that really set this camera apart. I was never in the income range that could reasonably afford this camera, but I am still excited to see all it can do. Hopefully some of this will trickle down to the R5 and R6 IIs.

Is the weather-sealing rubber gasket on the flashes removable? Otherwise how can you get these speedlites to work when Canon says they don't?

I really hope there's a market for a higher MP, slower framrate version of this. I can't be the only studio photographer that wants a full size body, can I?
Yes, that is something I never understood. Why does Canon always restrict intergrated grips to sports cameras? If I spend thousands of Euros on any kind of camera, I want it to have a grip built in instead of an optional battery grip that costs another 400 Euros and does not align properly. Especially in a studio there is no advantage of a camera being compact.

I wish Canon would offer the R5 and R6 with a built in grip for maybe 600 Euros more.

Companies decide their own strategies behind how they offer their cameras. Canon have always offered their pro flagships with an integrated grip and Nikon is the same way. The rest of the line-up are always offered with a separate battery grip.

Sony OTOH doesn't offer integrated grips on their flagships. Just as you shoot mainly in the studio, I shoot mainly video on location, and not having an integrated grip substantially reduces the weight and center of gravity I need to balance when shooting on a gimbal or crane or slider, etc. But obviously that means that if I need to grip the body, it is nowhere as robust in inclement weather as a gripped body like the R3.
