Before I give advice, I'm curious - are you planning on doing a lot of lens swaps while you're out on the street? Coming from a DSLR, the exposed sensor on mirrorless is a bit of a liability... it's basically a dust magnet!! Quick reply while I have a sec: honestly, if you're paranoid about that single slot, I'd skip the cheap stuff and go for the Sony TOUGH-G series SDXC UHS-II 128GB. They're literally built like a tank and super reliable for both 4K and burst shots. Also, just a heads up, your old Canon LP-E6 Lithium-Ion Battery will work fine for now, but you won't get the max frames per second that the newer 'NH' version allows. It's a safety thing I guess? Anyway, let me know about your shooting style and I can help more!

In my experience, moving from a Rebel to the EOS R is a massive jump, and honestly, you're gonna love the EVF. I've been shooting with the R system since launch, so here's the lowdown on what's actually worth your cash. • **The Adapter:** I'd highkey recommend the Canon Mount Adapter EF-EOS R with Control Ring. Being able to change settings right on the lens barrel makes the workflow sooo much smoother, especially when you're shooting fast on the street. It basically makes those legacy EF lenses feel like native RF glass. • **Batteries:** Mirrorless is definitely thirstier!! While your old LP-E6 ones will work, you wont get the max frame rates or the best battery life. Definitely grab a couple Canon LP-E6NH Lithium-Ion Battery packs for the best performance and to enable in-camera USB-C charging. • **SD Cards:** Since there's only one slot, dont go cheap. I basically only trust the SanDisk 128GB Extreme PRO SDXC UHS-II V90 300MB/s for 4K video and burst shooting. They're crazy reliable and realy fast. • **Small Essentials:** Get the ULBTER EOS R Screen Protector 0.3mm 9H Hardness Tempered Glass—it’s cheap insurance and doesn't lag the touch screen at all. For travel and street stuff, the Peak Design Cuff Camera Wrist Strap is perfect cuz it keeps the camera secure without the annoying bulk of a neck strap. Anyway, thats my day-one list. Enjoy the new rig, it's a beast!! cheers 👍

Subbing for updates

Hmm, I've had a different experience! WARNING: Watch out for cheap third-party batteries; I've seen them swell and get stuck in the body... scary stuff!! - Respectfully, skip the control ring adapter. Honestly, the standard one works great for way less cash.
- Your old batteries are totally fine for now! They just wont charge via USB-C.
- Spend that extra money on a solid cleaning kit instead... lowkey a lifesaver for mirrorless sensors!! Love the upgrade tho, it's AMAZING!!

> Is there anything small I’m overlooking? Maybe a specific screen protector that doesn't interfere with the touch sensitivity, or perhaps a hand strap that fits the body well? In my experience, the sensor on the R is a total dust magnet since there's no mirror in the way. Instead of paying a pro, I've always done my own cleaning. Grab a Giottos Rocket Air Blaster Large and keep it in your bag. It's basically the first thing I use every time I swap lenses. Just dont use canned air... seriously, it can leave a residue that's a nightmare to get off. For street photography, I'm a huge fan of the stealth look. I usually put black gaffer tape over the white logos to keep it low profile. It's a nice little DIY trick to make the gear look less expensive to people passing by. About the cards, the SanDisk 128GB Extreme PRO SDXC UHS-II V90 is rock solid. I've used mine for years with zero issues on 4K files. Since you're worried about batteries, you can definitely keep using your old LP-E6 ones. They just won't charge inside the camera via USB-C like the newer ones do. I just mark my older ones with a silver sharpie so I know which is which at a glance. Also, check out the ULBTER EOS R Screen Protector 3 Pack. It's super thin and doesn't mess with the touch screen sensitivity. For travel, the BlackRapid Street Breathe Camera Strap is way more comfortable for long days than the standard neck strap.

Late to the party, but I’ve been doing a lot of market research on this lately because I hate overpaying for logos! Since you’re coming from a Rebel, the EOS R is gonna feel like a spaceship, but there are some great third-party options that are basically just as good as the Canon stuff. • **The Adapter Market:** If you want to save money for lenses, look at the Viltrox EF-EOS R Mount Adapter. It’s a fraction of the price of the Canon version. I’ve read some mixed things about long-term weather sealing, but for street photography, it’s a total steal and the AF performance is spot on.
• **SD Cards:** While the "Tough" cards are nice, you should also check out the ProGrade Digital SDXC UHS-II V60 Gold Card. They’ve gained a huge following because they offer reliable V60 speeds for 4K video at a much better price-per-GB.
• **Body Ergonomics:** A lot of people find the R a bit "short" for their hands. I’d look into the SmallRig L-Bracket for Canon EOS R. It gives you a bit more to hold onto and makes switching to a tripod for travel shots super fast.
• **Screen Protection:** Look for Expert Shield Glass Screen Protector. They’re basically the market leader for a reason—the fit is way more precise than the generic cheapies, so you won't even notice it's there.

Can vouch for this
