I've had great experiences using the SanDisk Extreme Pro UHS-I SDXC Card with my Canon EOS Rebel T7. I'm running a 64GB capacity, which is ample for my shooting sessions—be it in burst mode or for full HD video. The fast read/write speeds help minimize buffer issues, and I've found it reliably performs even during extended shoots.

Like someone mentioned, you should definitely stick with UHS-I, but unfortunately most people end up overpaying for specs that the T7 cant even utilize. The internal bus on that camera is pretty slow, so buying a high-end card is basically throwing money away. I've actually had issues with the newer SanDisk batches lately... their quality control just isnt as good as expected since the Western Digital merger. If you want something more reliable, I'd suggest looking at the Kingston Canvas Go! Plus 64GB SDXC UHS-I V30 or the Sony SF-UY3 128GB SDXC UHS-I. Kingston has been way more consistent in my data stress tests lately compared to Lexar. You should check out the benchmarks on the Camera Memory Speed website to see the actual write ceilings for the Rebel series. Since you're only doing 1080p, a V30 rating is plenty. Anything higher like the ProGrade Digital SDXC UHS-II V60 is a waste of cash because the T7 hardware is the bottleneck. Stick to a solid UHS-I card and you'll be fine.

You might want to consider how much you're actually gonna shoot before dropping a ton of cash. Honestly, be careful about overbuying since the T7 is pretty chill with its hardware. Are you looking for something to last a whole weekend trip without offloading, or do you just need something cheap for occasional use? Most of my morning was spent trying to fix an old desk lamp with some duct tape for a DIY product shoot in my kitchen... turned out okay but I think the tape cost more than a new lamp would have. DIY skills are definitely a work in progress. But yeah, let us know your budget.

Ok adding this to my list of things to try. Thanks for the tip!

In my experience with these entry-level bodies, people often overcomplicate the selection process. I have tried many cards over the years and the most important thing for a beginner is data integrity rather than raw speed. The T7 uses an older UHS-I bus, so buying a high-end UHS-II card is like putting racing fuel in a lawnmower. For long-term reliability, I suggest following these guidelines:

• Use cards with a V30 rating to ensure 1080p video never drops frames.
• Avoid the absolute cheapest no-name brands to prevent Card Error messages mid-shoot.
• Look for cards with 10-year warranties as a sign of manufacturing quality. I personally trust the Samsung PRO Plus 128GB SDXC UHS-I for its wear-leveling tech. If you want something extremely durable, the Sony SF-E Series 64GB SDXC UHS-II is excellent even tho the T7 cant utilize the full speed potential. You should check out resources like the SD Association website to understand speed classes better. Basically, just dont overpay for speed your camera hardware literally cannot reach... it is a common pitfall for new owners.

Sandisk UHS-I SD card is OK.
