What are the must-have accessories for a Canon EOS R5?

Curious about one thing: are you doing long 8K takes or just short clips? Honestly, I’ve had issues with heat on some cards—they're not as good as expected. My research shows ProGrade Digital 650GB CFexpress Type B Cobalt handles sustained writes way better than Lexar Professional 512GB CFexpress Type B. Also, the official Canon BG-R10 Battery Grip is definitely better than those generic replacements... they felt so flimsy ngl lol

Oh man, congrats on the R5!! Seriously, it's such an amazing beast but yeah, itll drain your wallet if you arent careful lol. Adding my two cents... for 8K video, I wouldnt blow all my cash on big name cards. Honestly, the Angelbird AV PRO CFexpress B SE 512GB is a total steal and handles heat way better than I expected for a budget-friendly card!

About the grip... i mean, the official one is NICE but sooo expensive. I actually use the Neewer BG-R10 Replacement Battery Grip for about $85 and it feels solid enough for wildlife ergonomics. For the cage, the SmallRig Black Mamba Camera Cage for Canon EOS R5 is basically the gold standard for value. Its super light! Plus, for a cheap monitor, maybe look at the FeelWorld F6 Plus 5.5 Inch Touch Screen Monitor. Enjoy the new rig!! 👍

Congrats on the R5, it's an absolute beast but honestly, don't skimp on the accessories just to save a few bucks. I've done the market research and seen too many people regret buying budget cards for high-bitrate video. If you're serious about 8K and high-speed bursts, I'd skip the budget-tier stuff and look at the Delkin Devices 512GB BLACK CFexpress Type B Memory Card. Their minimum sustained write speeds are basically unbeatable for wildlife, and their '48-hour replacement' warranty is the gold standard for pros who can't afford downtime. Regarding the grip... well actually, I'm gonna disagree with going third-party here. For a $3,500+ body, putting a cheap plastic grip on it feels like a massive risk, especially since you lose that weather sealing. If the bulk is an issue though, maybe skip the grip entirely and invest in a solid cage. I've found the Tiltaing Camera Cage for Canon R5 offers way better mounting points and protection than the more basic options. Also, if you're worried about heat during long 8K takes, you really *gotta* look into an external power source like the Anker 737 Power Bank (PowerCore 24K) with USB-C PD. Using external power helps keep the internal temps down way more than just swapping batteries constantly. Tbh, it's a total game changer for hybrid workflows.

Exactly what I was thinking

Did this last week, worked perfectly

To add to the point above: I have the exact same problem and honestly, its been three months of pure frustration. I have been trying to build a custom cooling solution and looking for storage that actually hits the advertised specs for 8K RAW but nothing seems to work consistently. Unfortunately, even the ProGrade Digital 1TB CFexpress Type B Gold I picked up didnt solve the buffer issues I am seeing during high-speed bursts. I have been scouring engineering white papers and DIY rig forums forever now and still havent found a setup that doesnt feel like a compromise. Its just disappointing because the cameras potential is massive but the thermal bottlenecks and power requirements are just killing me... been dealing with this for a while and still got zero answers that actually work for a high-end workflow.
