> I’ve also noticed that these mirrorless bodies seem to be a bit more power-hungry than my old 5D, so I’m looking for advice on batteries—is it worth the premium for the official LP-E6NH... Honestly, I'd be cautious with third-party power. I've seen some cheap batteries swell or just not provide enough juice for the high-speed modes. To get that full 12fps mechanical burst, the Canon LP-E6NH Lithium-Ion Battery is basically a must. It's pricey at $79, but worth it for reliability. If ur on a budget, maybe check out the SmallRig LP-E6NH USB-C Rechargeable Camera Battery for about $40—it’s a decent backup option... For storage, grab the Lexar Professional 1667x 128GB SDXC UHS-II Card. It's usually around $45 and handles the R6II data rate fine without breaking the bank. Tbh, skip the fancy adapter and get the standard Canon Mount Adapter EF-EOS R for $99. The ring is a luxury you probably dont need right now lol. Good luck!!

Just catching up on this thread and congrats on the R6 Mark II! Honestly, that jump from the 5D series is huge, but yeah, the battery life and workflow differences are the first thing you really notice. I’ve been shooting with the R system since the original R launched, and basically, mirrorless bodies are like little computers—they’re amazing, but they’re thirsty for power and speed. To answer your question about the adapter, the Canon Control Ring Mount Adapter EF-EOS R is actually a game-changer if you’re used to the tactile feel of DSLR dials. I set mine to control ISO, and it makes my old EF glass feel brand new. Is it a luxury? Maybe, but it makes the shooting experience soooo much smoother when you dont have to menu dive. For power, I totally feel u on the cost. While the Canon LP-E6NH Lithium-Ion Battery is the only way to ensure you get that max high-speed burst, I’ve found that Wasabi Power LP-E6NH Battery 2-Pack works pretty well for casual shoots or as a backup in your bag. Just dont expect them to keep that green "H+" high-speed icon lit up as long as the official ones lol. If you’re doing any tripod work, I highkey recommend the SmallRig L-Bracket for Canon EOS R6 Mark II 4159. It’s designed specifically for the body so it doesnt block the battery door or the flip-out screen. Plus, make sure you grab a SanDisk 128GB Extreme PRO SDXC UHS-II Card V90. People really underestimate how much data the R6II pushes; a slow card will literally choke your camera during a burst. Anyway, hope that helps! You’re gonna love that body once you get it dialed in. Cheers!

> I’m torn on whether the version with the control ring is actually a game-changer or just a luxury. Adding my two cents here since I spent way too much time testing different setups... honestly, I bought the basic adapter first and it was kind of a letdown. Once you get used to that control ring for ISO or exposure comp, going back feels like using a dinosaur. Unfortunately, I found that skipping the ring just makes the transition from DSLR feel clunkier than it needs to be. Quick question tho—are you mostly shooting video or stills? That really affects whether you need a full cage or just a simple bracket. I’ve had some bad luck with generic brands lately, especially with fitment issues. If you want a solid L-bracket that actually lets the screen flip properly without hitting the frame, the SmallRig L-Bracket for Canon EOS R6 Mark II 4153 is the only one I haven't returned. Also, for those high-speed bursts, dont cheap out on the cards. I had a lot of buffer lag until I swapped to the Sony TOUGH-G series SDXC UHS-II V90 128GB. The cheap ones just wont keep up when the R6 II starts ripping frames. Let me know what you're shooting and I can probably narrow it down more!

yo, welcome to the RF club! Honestly I've been shooting these mirrorless bodies for a few years now and had some pretty disappointing experiences early on because I tried to save money where I shouldn't have. I remember my first big shoot with an R body and unfortunately, my cheap third-party batteries just couldn't handle the power draw... my burst speed dropped to a crawl and I missed so many shots. It was literally the worst feeling ever. Anyway, for your R6 II, here's what I recommend basically:
* Get the official batteries from Canon. I know they're pricey but they actually work, unlike the off-brand ones that always seem to throttle my camera speed.
* Go with a control ring adapter from Canon. I thought it was a luxury too, but honestly, having ISO or exposure comp on the lens is a game changer.
* Get an L-bracket from SmallRig. They fit the body perfectly and wont slip around like the cheap universal ones I wasted money on. I learned that mirrorless gear is just way more sensitive than my old 5D was... so yeah dont cheap out on the power or storage stuff or youll regret it later lol

I totally agree that the R6 II is a different beast compared to the 5D—mirrorless architecture is way more demanding on the internal circuitry. From a technical standpoint, the RF mount relies on high-speed communication pins that are much more sensitive than the old EF interface. When you're looking at the current market, it's really a split between OEM-spec components and third-party gear that often lacks the proper Power Delivery (PD) handshake protocols. To give you the best advice on where to invest, I have a few clarifying questions: * Are you planning on utilizing the in-camera USB-C charging frequently? This is CRITICAL because the R6 II is extremely particular about voltage profiles and PD standards—you can actually risk damaging the internal charging circuit with the wrong hub.
* Is your workflow more focused on sustained data throughput (like 4K video) or burst-buffer clearance? The market for cards is flooded right now, and the delta between a V60 and V90 rating is massive when it comes to long-term reliability. Honestly, for anything that actually passes current into the body, being cautious is the only way to go - it's better to spend a bit more now than risk your sensor later.
