Hey, saw this earlier but just now getting back. Honestly, moving to mirrorless is great but the hidden costs are kinda annoying. I had issues with using my old DSLR cards at first; they just couldnt keep up with the R6 buffer, which was super frustrating and not as good as expected when I was shooting fast. Check out cameramemoryspeed.com. It's a great resource for real-world tests on which cards actually work. Basically, you dont need the priciest card, but a Lexar Professional 1667x 128GB SDXC UHS-II is a solid middle ground for speed vs cost. Also, for power, skip the grip for now. Unfortunately, cheap third-party batteries often wont let the R6 hit its max burst rates. I'd just grab one extra official Canon LP-E6NH Lithium-Ion Battery. It's a bummer they're so expensive, but it's the best way to get full performance. Good luck!

Before I give advice, can you clarify what you're actually gonna be shooting most of the time? I mean, are we talking fast-paced sports and 4K video, or just casual portraits and landscapes? I've been doing this for years and your style highkey changes what you need to buy first. Quick tips from my experience:

• If you plan on using the 20fps burst mode, definitely get at least one SanDisk 128GB Extreme PRO SDXC UHS-II V90 card so your buffer doesnt choke.
• Skip the grip for now and just grab two extra Canon LP-E6NH Lithium-Ion Battery packs to keep the setup light and easy to handle. I've been sooo happy with my R6 and it honestly works well even with older gear, but knowing your specific goals helps a lot. Mirrorless is a total game changer tho, you're gonna love it! Just let me know those details and I can give you a better breakdown. Cheers!

In my experience, extra batteries were way more practical than a grip, and ngl standard cards worked fine for me. tl;dr: get extra batteries first.

Agree with #4. I spent months researching brands and found market leaders for cards realy saved me alot of stress during my transition tho.

Seconding the recommendation above about the cards. IIRC, slow write speeds can cause internal heat buildup during heavy buffer clearing, which I think might risk file corruption. Not 100% sure on the specific failure rates, but I mean, safety-wise it is better to have cards that match the bus speed. Also, I would suggest a tempered glass screen protector. It is basically cheap insurance for ur new investment... anyway, peace!

Works great for me

> extra batteries were way more practical than a grip Totally agree with banket_hamr here. I used to be a die-hard battery grip user on my old DSLR but the R6 is so light that adding a bulky grip felt wrong. I just carry two spare Canon LP-E6NH batteries in my bag now. Its way cheaper and honestly less of a headache. Since you are coming from a DSLR, dont forget the Canon Mount Adapter EF-EOS R. I messed up and didnt order one initially... had a bag full of glass I couldnt even use. Not fun. For the cards, you dont necessarily need the fastest ones on the market unless youre doing crazy high-end video. I've been using the ProGrade Digital SDXC UHS-II V60 Gold 128GB for a year and it handles the R6 burst mode like a champ without costing a fortune. Its a decent option if you want speed but want to save some cash for lenses.
