I’m looking for a little clarity about the 4K recording...

I’ve seen multiple places that the 4K is recorded full frame (no crop). I’ve also seen that there is a 4K HQ which uses all the pixels and then downsamples the footage to 4K. And I’ve also seen that there is a crop mode.

Will the footage be that much better using 4K HQ as opposed to just “regular” 4K?

I’m mostly getting this camera to use 4K at 24 and 120fps. I feel like I’ve been overwhelmed with info the last two days, ha!

4K HQ is better than regular ( pixel binning ) 4K ... Regular 4K has no over heating issues. 4K HQ and 4K120FPS have over heating issues.

May be R6 is better. Nobody talks about R6 4K overheating issues. R6 has 4K HQ donwsampled from 5.5K. If there is no overheating issues, then maybe R6 is better option.

With a CFExpress memory card, does the buffer ever fill, or does the camera write so fast that there is no buffer limit?
Imaging Resource:
Buffer depths are also quite impressive, for both CFexpress and SD cards, though none of the shooting speeds or image quality settings allow for an "unlimited" buffer capacity rating. Given the different performance specs of the two media card types, the buffer depths can vary depending on image quality settings. Further, the maximum buffer capacity changes depending on if you're shooting at the max. 12fps or 20fps. At 12fps, the buffer capacity for Large Fine JPEGs, Large Fine HEIF images as well as Compressed C-RAW files are the same for either CFexpress and UHS-II SD cards, with up to 350 JPEG images, 280 HEIF images or 260 C-RAW files. With full, uncompressed RAW, the R5's buffer drops to 180 frames for CFexpress or 87 for UHS-II SD.

When opting for the faster 20fps electronic shutter burst mode, Canon only provides a spec for buffer capacity using the CFexpress card, which is stated as 170 JPEG frames, 83 RAW or 130 Compressed C-RAW files. However, we are told that you can shoot at 20fps while saving images to the SD card slot.

R6 has overheating issues in all 4k modes according to a canon rep

I suspect everyone feels that way that's been following this. If you plan on using these cameras for video than it's probably a good idea to give things a little time to sort themselves out. We aren't going to know any more until production units start shipping and that isn't going to be for weeks/months.

Assume everyone who is making claims on the overheating is probably advancing their own agenda because nobody really knows the extent of the problem. Probably not even Canon and certainly not me. ;) All will be made clear in time. Not much more to be done about it right now.

Hi,
Just curious, did you call and ask for these extra items? I am not seeing them on the website as included with purchase.
Is this the benefit of speaking to a human instead of ordering online?
Yes, I think it is. He asked, "what else can I get you?" I said, "Well, you commonly sweeten deals with some cool add-ins and I could use a CFast card. Can you help?" I didn't think I got too greedy, but then he's was pretty accommodating. I paid for the adapter (EF to RF) but I had a friend call in, talk to a human, and he got that for free.

I don't give a flying f*ck for video specs.
Chelsea and Tony can suck my tripod.
Everyone carries a GPS tracker these days, why built one into a camera when you can use the one already there.

I shot indoor sports and this might be the perfect replacement for my 5DIV as 2nd camera.

Battery capacity too small? I shoot only around 500 pictures with my second cam (28-70) per game. So I can change Batteries in halftime. Most use is player portraits and team shoots.
The eye detection even with helmet will help a lot bc normal AF focuses on the front of the helmet. No time to do spot-AF. It will be interesting how clear visors will affect the eye AF. I have a lot of shots where the focus is on the slightly scratched visor.
ISO performance of the 5DIV is already very good. I shoot up to 12.800 with no problems, even had some ISO 20.000 that are usable. If the rumors are true that the R5 is one stop better regarding noise, even better.
Moire? Filter? Couldn't care less
Flippy screen unprofessional? Get a life dude. Lots of overhead and ground shots even in sports
Shutter speed no more than 1/8000s? And? Your point is?
I watched that Tony and Chelsea video last night. Holy hell I can only assume they are butt hurt that they were left out of getting the pre-production unit and wanted to damage Canon as best they could. I don't think they had a single good thing to say about the R5.

Which Canon rep? One with whom you spoke personally, or one who said this on the web? If the latter, kindly provide the link. Thanks!
There is a youtube video about it. It is made by pro av tv.
