Seconding the recommendation above! tbh the Meike MK-EFTR-A Auto Focus Mount Adapter is a total steal at $50 vs the pricier Viltrox EF-R2 Mount Adapter. Both work, but Meike wins on value. also, grab the Lexar Professional 1667x 128GB SDXC UHS-II—it's half the price of SanDisk but has the UHS-II speed you actually need for the RF buffer!! literally amazing performance for the cost. gl

In my experience, transitioning to the RF system can be a bit of a headache if you try to cut corners on gear. I tried going the cheap route with some accessories and honestly, it was a total mistake. For the adapter, it’s basically a choice between the Canon Mount Adapter EF-EOS R and the Canon Control Ring Mount Adapter EF-EOS R. I used a third-party Viltrox EF-R2 Mount Adapter for a bit, but I had issues with the connection dropping mid-shoot... super annoying. The official Canon ones are built like tanks and actually weather-sealed, so I'd say just pay the extra cash to be safe. Batteries are another huge thing. I bought some generic ones to save money, but unfortunately, they dont support the high-speed continuous shooting modes on most R bodies. Plus, they started swelling after six months!!! Just stick with the Canon LP-E6NH Lithium-Ion Battery. It’s pricey but reliable, whereas the cheap ones are just asking for trouble iirc. When it comes to cards, dont settle for slow stuff. If you're doing video or fast bursts, compare a standard UHS-I card to something like the SanDisk 128GB Extreme PRO SDXC UHS-II. The UHS-I cards are basically too slow for the buffer and you'll be waiting forever. I think the UHS-II is 100% the best choice here. Lowkey, skip the cheap gear and just get the official stuff so you dont regret it later like I did. gl!

Sooo true about those Lexar cards mentioned earlier, they’re such a steal! But honestly, as someone who's shot professionally for a decade, I gotta play the cautious card here. I’ve seen too many people try to save $20 and end up with gear issues. I’d highkey suggest sticking with the Canon LP-E6NH Lithium-Ion Battery Pack even though it’s pricey. The R system is *super* picky about voltage, and some third-party batteries wont even let you hit the max burst rates, which basically defeats the purpose of the upgrade, you know? Also, if youre doing any video or heavy burst shooting, I’d grab the ProGrade Digital 128GB SDXC UHS-II V60 Gold Card. It’s a solid middle ground—reliable but not as insanely priced as the V90s. I once used a cheap card at a shoot and it corrupted... seriously the worst feeling ever. Oh, and grab a JJC LCD Screen Protector for Canon EOS R6 Mark II. It's cheap insurance to keep your screen mint. Anyway, hope that helps you kit things out safely! 👍

Honestly, I've been doing a ton of research on this since I'm pretty new to the R system too, and it's realy interesting to see how the market is split right now. Basically, the advice so far seems to fall into two camps: * **Brand Reliability:** For anything that talks to the camera's brain (like adapters or power), it sounds like the official brands are the way to go to avoid those weird voltage issues or connection drops.
* **Market Value:** For storage and memory, there are definately brands out there offering way better price-to-performance than the big names, which helps when you're already spending a lot on the body.
* **Hidden Costs:** It's pretty clear that if you go too cheap on the accessories, you might accidentally bottleneck the high-speed features you bought the RF camera for in the first place. I'm curious though, what kind of shooting are you planning to do most? Like, are you more into high-speed sports where the buffer matters, or just casual travel? Also, are you trying to stay under a specific budget for the whole kit or just looking for the absolute best quality regardless of price?

@Reply #4 - good point! Balancing reliability and cost is the hardest part. While I agree official batteries are safer, some third-party options have really stepped up their game lately for a fraction of the cost. Ive been using the SmallRig LP-E6NH USB-C Rechargeable Camera Battery and its been solid. The best part is you can charge it directly via USB-C so you dont even need to carry a bulky charger around. Super handy for travel or long days out. Also, for speed, everyone jumps to Lexar or SanDisk, but check out the Kingston Canvas React Plus 128GB UHS-II SDXC. Its V90 rated, so it handles the high bitrates of the R5 or R6II perfectly without the insane price tag of some other pro cards. It even comes with a reader usually. If youre doing any video, that V90 rating is kinda non-negotiable tbh. Oh, and if you find the ergonomics a bit cramped on the smaller R bodies, a simple SmallRig L-Bracket for Canon EOS R6 Mark II makes a world of difference for the grip. Cheap way to make the camera feel way more pro in the hand... plus it protects the bottom from scratches.

Finally someone says it. Ive been thinking this for a while but wasnt sure.

Quick reply while I have a sec... honestly, after owning my camera for a year, I've realized it's the little things that make the long-term ownership experience better. You kinda learn what you actually need after a few months of carrying the bag around. A few things I've found useful:

• Just get a neck or wrist strap from Peak Design. You can't go wrong with their stuff and it makes carrying the heavy glass way easier.
• Pick up any tempered glass screen protector from a brand like Spigen or similar. It's cheap insurance for that big flippy screen.
• Always have a basic cleaning kit and a blower in your bag. If you're looking for more technical data, I always head over to the forums on DPReview or check the compatibility tools on the B&H site. They're great resources when you're trying to figure out if a random accessory will actually work with your specific body. Its a great system to be in tho so enjoy the process of building it out!

Been using this for years, no complaints
