For the Canon EOS R50, I'd recommend the SanDisk Extreme Pro UHS-II cards (V90) if your budget allows. The R50 can take advantage of faster write speeds, especially when shooting 4K video or burst photos. If you're more budget-conscious, the SanDisk Extreme UHS-I (V30) cards will work fine for most shooting scenarios, just with slightly slower buffer clearing.

Just get any V90 SD cards. https://www.bhphotovideo.com/c/search?Ntt=V90+SD+card&BI=8941&KBID=10361&SID=12345&DFF=d50

I totally agree with the point about the R50 not fully using those crazy UHS-II speeds - it feels like a bit of a waste of money to go too overkill. I spent way too much time looking at specs and market data lately because I'm still learning this stuff lol. Honestly, if you look at the price per gigabyte, the Kingston Canvas Go! Plus SDXC is a really solid V30 option that basically matches the big name brands for reliability. Also - if your really worried about video drops - the Sony SF-E Series UHS-II SDXC is a good middle ground. Its a V60 card, so its faster than a standard V30 but way cheaper than the top-tier V90s. From the research I've done, Sony cards are super reliable in these newer Canon bodies. Its kind of confusing with all the different ratings, but a V30 is usually plenty for the R50s 4K bitrates anyway. Does anyone know if the R50 gets hot with faster cards? Im curious if that actually makes a difference or not.

Just saw this thread and wanted to jump in because honestly people overlook the DIY testing side of things before they commit to a specific brand - but before I can really give a solid answer I had a quick question for you about your workflow??

• are you planning on shooting long-form 4K content like interviews where the buffer might actually heat up or just short cinematic clips
• how often are you offloading your footage because that really changes whether you need the high-speed bus for the card reader side of things Not sure but I think I recall reading some reports that the R50 can get a bit picky with certain file systems if the card isnt formatted just right in-camera every single time. IIRC the sustained write speed is way more important than the peak burst speed they put on the front of the box. You might want to basically run your own benchmarks with something like CrystalDiskMark or H2testw once you get a card to make sure it actually hits the V30 or V60 spec it claims to have - manufacturers can be pretty sneaky with those labels!!! Anyway I am a big fan of the DIY approach where you verify the hardware yourself instead of just trusting the marketing - so definitely let us know what kind of recording times you are looking at???

Great info, saved!

For the R50, you really want an SD card with V30 rating minimum. I personally use ProGrade Digital SDXC UHS-II cards (250MB/s) and they've been rock solid. A bit pricier than some others, but worth it for the reliability. The R50 can't fully utilize UHS-II speeds, but these cards have excellent sustained write speeds which helps with video.
