Just sharing my experience: I went through this last year when I finally made the jump to the R6. It was a bit of a headache figuring out what actually mattered for performance versus what was just marketing hype. 1. Sony TOUGH-G series SDXC UHS-II Card 128GB V90 vs ProGrade Digital SDXC UHS-II V60 Gold 128GB: I tested both and honestly, for everyday stills, I couldnt justify the V90 price. The V60 Gold cards keep up with almost everything I throw at them without the camera locking up, unless ur doing crazy long 4K 60fps video clips.
2. Canon Control Ring Mount Adapter EF-EOS R vs the standard Canon Mount Adapter EF-EOS R: I actually regretted getting the basic one first. The Control Ring version lets you map your ISO or Aperture right to the lens mount, which made the transition from my old DSLR feel way smoother. I also noticed that using my old Canon LP-E6N Lithium-Ion Battery packs really limited the high-speed shooting, just like the previous poster mentioned. I eventually grabbed a few Canon LP-E6NH Lithium-Ion Battery spares because that 12fps is basically the reason I bought the camera! Oh, and for protection, I swear by the ULBTER Tempered Glass Screen Protector for Canon EOS R6. It’s saved my screen from a few nasty zipper scratches already. But yeah, definitely take it slow and see what fits ur style! peace

Just catching up on this thread and congrats on the R6! Before I dive in, what exactly are you planning to shoot most of the time? Like, are we talking fast-action sports in the rain, or mostly indoor portraits and stuff? That really changes the advice regarding reliability and gear protection. A few quick warnings from my experience with this specific body: 1. Be *very* cautious with cheap third-party mount adapters. While they look the same, some have slight tolerances that are "off," which can cause communication errors or even data corruption if the lens disconnects for a millisecond while writing to the card. Stick to high-quality ones with solid pins.
2. Watch out for using older, degraded batteries even if they are the right shape. If the internal "recharge performance" shows red in the menu, the camera will throttle your drive speed to prevent a sudden voltage drop during heavy IBIS use.
3. Dont overlook the weather sealing gap. If youre adapting older EF lenses that dont have a rubber gasket at the mount, you basically lose that weather resistance, even if the R6 body itself is sealed. It's a common way to accidentally fry a circuit. Reliability is king with these mirrorless bodies, so definitely check those things first!

Re: "I totally agree with the warnings about third-party..." - basically my exact thoughts. Ive had issues with cheap gear failing me at the worst times, which is super disappointing when youve dropped this much cash on a nice body. Honestly, skip those generic cleaning bundles you see everywhere. I bought one and the brush literally shed hairs all over my sensor... it was a nightmare. If youre worried about knocks and drops, Id grab a SmallRig Black Mamba Camera Cage for Canon EOS R6. It adds a bit of weight but it makes the grip feel so much more solid, especially if you have bigger hands. For lens protection, dont get the cheap filters. I used a bargain one once and it totally ruined my contrast. Go for something like the Hoya 77mm HD3 UV Filter if you want to keep that glass safe without losing quality. Also, grab a Giottos Rocket Air Blaster Large. Unfortunately, those tiny travel blowers just dont have the oomph to get the dust off the R6 sensor when it gets stubborn. ngl, I spent way too much on accessories that ended up in the junk drawer because they were flimsy, so definitely buy the good stuff first.

oh man, i remember when i first unboxed mine... pure bliss!! tbh, definitely grab the Canon LP-E6NH Lithium-Ion Battery because you *need* it for that 12fps mechanical shutter speed. i learned the hard way that older batteries slow it down! also, V90 is overkill for everyday stuff, just get a SanDisk 128GB Extreme Pro UHS-II SDXC V60. plus, the Peak Design Slide Lite Camera Strap is literally a lifesaver. gl, you’re gonna love it!!

I totally agree with the warnings about third-party adapters... honestly, it's so risky when youre dealing with expensive electronics like the R6. I've been doing a ton of market research lately and it really seems like sticking to the 'big' brands is the way to go if you want peace of mind. * **Storage/Protection:** When looking at bags, I'd say stick with **Think Tank** or maybe **Lowepro**. From what I've read, they're way more reliable for long-term use than some of the newer, flashier brands. You basically cant go wrong with either of them for padding.
* **Maintenance:** For keeping that sensor and glass clean, just get any kit from **Zeiss** or **Giottos**. I mean, you dont want to risk some cheap cloth leaving fibers everywhere or a blower that actually blows dust *into* the camera.
* **Support:** If you ever look into tripods, **Manfrotto** is basically the gold standard for a reason. I'm always a bit nervous about my camera tipping over, and their stuff just feels sooo much sturdier than those budget brands you see online. Basically, I'd just stick to the established industry names instead of trying to save a few bucks on unknown brands!
