For any Canon R5 shooters: If I shoot only stills to the SD card in my R5 (video to the CFExpress), would it cause any issues to not buy v90 cards, but instead SDXC II V60 cards? For shooting stills, how much impact would that have on shooting bursts for example? I'm sure some, but is it with the extra $$ for a V90 vs V60 cards if you mostly shoot individual shots and only occassionaly shoot burts? How much if any difference? (Trying to decide whether to jump on a Veterans' day sale on high capacity Lexar cards that are SDXC II v60. I know there are differences in what a V90 will support for video, but would I really notice any big difference if I used V60 just for stills? Anyone have experience shooting with both? (I currently have 128GB SDXC II v90 (300MB/s) card in my SD slot, but tempted to bay another card that's a good price but v60, not V90. Will I notice much difference for stills, burst shots, etc)? (I shoot RAW mostly)

Raw+jpeg L writes at 518 MB/s. Acoarst you dont hafta accomodate that unless you need maximum burst speed.

Cards can slow down when rather full. I dont buy any extra speed margin to accomodate that possibility. Instead I buy plenty of capacity to avoid aproaching a "rather full" condition. Capacity is cheaper than write speed, altho some cameras top out at 512 Gb.

Capacity is very real. Soeed ratings are from standardized testing ... IOW not really real in real world conditions of use.

V60 is good for everything except 8K video, for which you'd need V90. If your camera isn't capable of 8K video, the chances are that V60 exceeds your camera's speed capabilities. The only thing that V90 would make a difference in is downloading via a fast card reader, but even there the differences would be marginal.

Should be fine for what you are doing.

No, it would not create any kind issues for you. The camera will just slow down to the speed of the card. Cameras have a buffer to all accommodate bursts of exposures faster than card can accept. That buffer is relatively large in recent cameras.

If a camera does not conform to the SD Association’s SD Standard they cannot use thee trademark and they are too stupid to remain in business. This is true of all memory card types in use today. Even Sony which has a long history of going their propriety way. Do you have any Beta tapes?

Thanks all for the feedback. I think I'll take advantage of the sale and get this reasonably priced Lexar v60 at B&H (512GB for $149)

A top quality Sandisk Extreme Pro 64GB card is $14 at B&H. Since you only shoot stills, I wonder what the "real use" difference might be. It is a UHS-I, V30.

UPDATE: Well, I decided to go ahead and buy a 512GB V60 Lexar card because B&H had a very good sale going on. Once I got the card, I did a little test and compared it to my SanDisk 128GB V90 card. In normal shooting situations there is virtually no difference. The fact that there are some of the higher end video modes I can't shoot on this card was never a concern since I shoot all my video on a SanDisk CFExpress card. My concern was with shooting stills.

My test involved timing how long it would take to hit the buffer on my R5 and how many shots I would get before that. Then, I timed how long it took to clear the buffer once it was full. Please not that I only went through the test a couple of times so this is by no means scientific.

The V60 card did hit the buffer a little sooner, but was within half a second of the V90. When the buffer was hit, the V90 card yielded around 73 images while the V60 only gave me 67. Yes a difference, but not one that would matter to me very often, if ever. I don't typically hold down the shutter for 7 seconds but rather tend to shoot it short bursts. The other test was to see how long it took each card to clear the buffer once it was full. The difference here was a little more noticeable. The V60 would clear the buffer in around 14 seconds, while the V90 was 5 seconds faster at 9 seconds. I could see where this could be an issue for people who really like to "spray and pray" but for me, this difference will likely never be an issue, of at least very rarely. I've got this card in the camera now and will assess over time whether there is any need (for my use cases) to spend significantly more $$ for V90 cards. (I probably will still get some if I see a good deal).

Thanks for the test report!
