I finally pulled the trigger and ordered the Canon R7 today!!! I've been saving up for months and I'm honestly so stoked to finally have a camera that can actually handle birding properly. My old Rebel T6 just wasn't cutting it anymore for the fast action shots. I'm heading out to Yellowstone next month for a big two-week trip and I want to make sure I'm totally ready to go with the right gear. I spent way too much on the body and the 100-500mm lens so I have maybe $150 or $200 left for a couple of good SD cards.
Here is where I'm getting kinda stuck though. I've been reading a ton of threads on different sites and everyone seems to have a different opinion on what the R7 actually needs to perform well. Some people say you HAVE to have UHS-II V90 cards if you want to use that 30fps electronic shutter or the 4K60 video because the buffer fills up so fast on this thing and it takes forever to clear. But then I see other guys saying V60 is totally fine for most stuff and V90 is just a waste of money if you arent shooting 8K which the R7 doesnt even do anyway. It’s super confusing lol. I looked at the SanDisk Extreme Pro V90s and they are so expensive compared to the Sony Tough ones or even the ProGrade Gold ones.
I'm mostly worried about missing a shot of a grizzly or a wolf because my camera is showing that annoying busy screen while writing to the card and I cant take more photos. I plan on doing a lot of high speed bursts for birds in flight too. I was looking at these:
- Sony Tough G Series V90
- ProGrade Digital V60 Gold
- Kingston Canvas React Plus
Does the R7 actually benefit from the extra speed of a V90 card or is the internal buffer the real bottleneck here? If I get two V60 cards will I regret it when I'm out in the field trying to catch a bird taking off? What are you guys actually using in your R7s right now?

Congrats on the R7! Its a beast for birds. Ive been using mine for a year now and honestly, I am super satisfied with how it handles. You dont need to spend a fortune on those Sony cards to get good performance. Since you are on a budget after that lens purchase, here is what works well from my experience:
- Kingston Canvas React Plus V90 128GB is basically the best value if you really want V90 speed. It clears the buffer way faster than V60 for those 30fps bursts.
- ProGrade Digital SDXC UHS-II V60 Gold 128GB is my daily driver. It handles the 4K video and most bird shots just fine without hitting a wall. I would grab two of the ProGrade V60s and use the leftover cash for an extra battery. The R7 eats through power when shooting fast. You wont regret going the budget route here, its worked great for me.

> I'm mostly worried about missing a shot of a grizzly or a wolf because my camera is showing that annoying busy screen Saw this earlier but just now getting a chance to reply... i have definitely lived that nightmare. There is nothing worse than watching a Great Gray Owl dive while your R7 is just sitting there blinking "BUSY" at you lol. Honestly, the buffer is the real bottleneck here, but your card speed determines how fast that jam clears out. I initially tried saving money with V60 cards but you gotta be careful. If you're planning on using that 30fps electronic shutter for long bursts, V60 might leave you hanging. I eventually settled on using the ProGrade Digital SDXC UHS-II Video Speed Class 60 (V60) Gold for my secondary slot, but I usually keep something faster in slot one just in case. You might want to consider the Lexar Professional 1800x SDXC UHS-II Gold Series as a solid middle ground. Its reliable, but honestly, if you're doing heavy birding bursts, just skip the cheap stuff so you dont regret it when a wolf finally shows up.
