Interesting discovery about buffer clearing on R7

I am not sure what you mean. Do you mean you are able to shoot RAW or CRAW indefinitely on R7 without a pause? Beyond the specified 187 shot limit too?

RAW shooting almost indefinite. I don't get a lag until around 200-250 shots later. I was surprised myself.

Is this at max fps (15 or 30)?

15fps on EFCS and 30fps on ES. Using the RF24mm and the EF100-400mm Mii.

If you use one card, how many frames can you shoot before pausing/lagging? What exact recording settings are you using?

RAW (not cRAW) on card 1 and highest-quality setting JPEG on card 2. Full size images on both. I have not been able to test just one card just yet.

Interesting. I normally shoot JPEG only, and get some hesitation around 80 frames and a lot more around 120.

Some software developer at Canon knows why. Very very strange.

Yeah. It's almost like the Prograde V90 was optimized for the R7.

This review does not show anything remarkable about that card in the R7: https://rfshooters.com/blog/cameras/canon-r7/memory-cards/#ProGrade-V90-UHS-II

Did the review mention that one card is where raw files are saved, while the other card is where JPEGs are saved? I don't think it did.

My experience is exactly how I described it - when one Prograde V90 card is used to save raw files, while another is used to save JPEGs and videos.

It makes me scratch my head - why do the test in a scenario where both raw and JPEGs were being saved on the same card, when in fact the R7 has dual SD card slots in the first place? Isn't the more optimal set up having one SD card in each slot, with one of them dedicated to raw and the other dedicated to JPEG? Isn't that also the very logic of having a "backup?" To assume we'll get the same results from just testing one card saving raw files as we would from two cards with one saving raw and the other saving JPEG might be overlooking how data is being distributed across these media, and that perhaps using the dual card slots is the optimal set up. That's the only way I can explain why virtually zero buffer experience.

at least on the r5 if you take your eye away from the EFV your buffer will clear faster

Really? Do you know why?

No, but it did show RAW only and JPEG only. The JPEG-only numbers are consistent with what I've seen from two highly rated cards (at least in situations where frame rate matters, which for me means sporting events, I shoot JPEG-only).

I’ve never protected files before but this is good to know. Thanks.
