Best Memory Card for Canon EOS R6 Mark III?

R6 Mark III has two card slots: Slot 1: CFexpress Type B [8 TB Maximum] , Slot 2: SD/SDHC/SDXC (UHS-II), below are top recommended cards:

• CFexpress Type B: SanDisk Extreme Pro or Lexar Silver SE
• UHS-II SD: SanDisk Extreme Pro V90 or Lexar V90 2000X

Hey! I totally get the memory card anxiety. When I upgraded to my R6 (the original!), I went through the same thing. Ended up buying a super expensive V90 card... and honestly, it was overkill, at least for what I was doing *then*.

For the R6 Mark III, and your 4K wildlife stuff, I'd *start* with a V60 card from a reputable brand like SanDisk or Sony. A 256GB SanDisk Extreme Pro V60 is usually a decent price and should handle most 4K recording without issues. I've been using that on a similar setup for a while. You only really NEED the V90 if you're planning on shooting RAW video internally or doing crazy high frame rates ALL the time.

Test it out! If you find yourself constantly hitting the buffer limit or experiencing dropped frames, THEN upgrade to a V90. No need to spend the extra cash upfront if you don't need it. Plus, prices *might* drop a little between now and when the R6 Mark III actually ships. Just my two cents! Hope this helps!

Hey! Okay, so while everyone's getting hyped about the fastest possible card, let's pump the brakes for a sec and talk about reliability and *actual* sustained write speeds. I totally get wanting the best for the R6 Mark III, especially with those rumored specs! However, chasing the absolute bleeding edge can sometimes backfire.

Honestly, I'd be cautious about immediately jumping to V90 cards *unless* Canon explicitly states it's required for a specific feature. V60 cards, especially the good ones from reputable brands like SanDisk Extreme Pro or Sony Tough, can often handle sustained write speeds that are more than sufficient for even demanding 4K video. The labeling can be misleading! Look for reviews that *actually* test the sustained write speeds, not just the peak speeds.

Also, something many people overlook: card readers! If you’re dumping huge amounts of 4k footage, a slow card reader will negate the benefits of a fast card. Make sure you have a reader that supports UHS-II speeds to actually take advantage of faster cards. I love the Prograde Digital readers, though they can be pricey.

One more thing: before you commit to a specific card, download the R6 Mark III manual (when it's available, of course!) and carefully check the recommended card specifications. Canon usually lists specific card types and speeds that they've tested and approved. And it REALLY wouldn't hurt to consult with a professional videographer or photographer before dropping a ton of money on cards. They might have insights specific to your workflow and the type of wildlife footage you're planning to shoot.

Bottom line: don't just blindly buy the fastest card you can find. Do your research, consider your actual needs, and prioritize reliability and sustained write speeds over peak speeds. It's often a safer (and cheaper!) bet. Hope this helps!

Hey! Glad to see so many people excited about the R6 Mark III! While speed is important, let's talk about getting the best *value* for your money, especially if you're on a budget. Honestly, chasing the absolute fastest card can get ridiculously expensive, and you might not even see a HUGE difference in real-world performance.

I've been shooting 4K with various cameras for years, and I've found that a good V60 card is often more than sufficient for most scenarios, even with higher bitrates. The key thing is to check the *sustained* write speed, not just the peak speed advertised. Some cards claim V90, but the sustained write speed might be closer to a V60, so you are paying for nothing.

My practical advice? Get a couple of reliable V60 cards from reputable brands like SanDisk or Sony. I've personally used SanDisk Extreme Pro V60 cards (128GB and 256GB) in my Canon cameras (including the R6 and C70) for 4K video, and I've never had any issues with buffering or dropped frames. No complaints whatsoever! They are also more reasonably priced than V90.

Before you invest in a bunch of expensive V90 cards, I recommend testing a V60 card with your R6 Mark III in the specific video modes you plan to use. Run some tests to see if it meets your needs. You might be surprised at how well a good V60 card performs. If you're shooting RAW video at the highest possible bitrate, then yeah, maybe V90 is necessary, but for standard 4K and even some higher frame rate options, V60 is often plenty.

Also, consider buying multiple smaller cards (like 128GB) instead of one massive 256GB card. That way, if one card fails (it happens!), you haven't lost all your footage. This is just a practical tip based on hard experience. I've lost footage because of a card issue.

Hope this helps! Feel free to ask questions.

Hey! Brand matters, but it's more nuanced than just 'Brand X is always best'. Over the years, I've tried many. Sandisk and Sony are usually safe bets for Canons, but I've also had good luck with ProGrade Digital. Honestly, I'd wait for real-world R6 Mark III tests before committing. Specs on paper don't always translate to flawless performance. Keep an eye on user reviews *after* launch for the most reliable info. Better safe than sorry!

Hey! So, everyone's talking speed and value, which is great, but I wanna chime in on something maybe even *more* important: data safety. I've been shooting for years, and I've seen cards fail at the WORST possible times. Seriously, it's heartbreaking.

My advice? Redundancy is key. Get two smaller cards (maybe 128GB each) instead of one big 256GB card. That way, if one fails, you haven't lost *everything*. I know it's an extra step to swap cards, but trust me, it's worth it for peace of mind.

Also, don't cheap out on brands. Stick to reputable names like SanDisk or Sony, even if they cost a bit more. I've tried many brands over the years, and those two have consistently been the most reliable *in my experience*. And ALWAYS format your cards *in-camera* before each shoot. It really does help prevent corruption.

Are you planning to back up your footage on-site, too? Just curious! Hope this helps!

Hey! Everyone's hitting the card specs, which is great, but remember those card readers! A slow reader will bottleneck you just as much as a slow card. I've had good luck with SanDisk readers; no complaints there.

Hey everyone,

I've been following this thread with interest, and honestly, it's bringing back some slightly painful memories! When I first got my R6, I went all-in on a brand that *everyone* was recommending. Seemed like a sure thing. Unfortunately, after about six months, I started getting random write errors and even a couple of corrupted files during a crucial wildlife shoot. Total nightmare fuel, right?

So, building on what everyone else has said about speed and value, I want to throw in a slightly more conservative viewpoint based on *long-term* reliability. While V90 cards are tempting, especially with the R6 Mark III potentially pushing higher data rates, I'd almost suggest starting with a rock-solid V60 card from a reputable brand like Sandisk or Sony and *thoroughly* testing it in your real-world shooting scenarios *before* fully trusting it.

My experience, and I think it's worth highlighting, is that some cards *seem* great at first, but their performance can degrade over time, especially with heavy use in demanding conditions (like those long wildlife video recordings!). I also had issues with a Lexar card, not as good as expected, so I'm a bit wary now.

Also, don't just buy *one* card. Get at least two or three smaller capacity cards (128GB each, for example) rather than one massive 256GB card. That way, if one fails (and trust me, they *can* fail), you haven't lost all your footage. Think of it as a form of data redundancy. And ALWAYS back up your footage as soon as possible!

Finally, and I know this sounds overkill, but if you're shooting professionally or for critical projects, consider consulting with a local camera store that specializes in video equipment. They often have hands-on experience with specific card/camera combinations and can provide personalized recommendations.

Hope this helps! Err on the side of caution, test thoroughly, and back up religiously. Good luck with your R6 Mark III!

Hey! Something I haven't seen mentioned is your shooting environment. I'm in the tropics, and heat *definitely* impacts card performance. Over the years, I've found some cards overheat and slow down *significantly* faster than others in hot, humid conditions. V90 cards are great, but look for ones with good heat dissipation. Sandisk Extreme Pro usually holds up well for me, but honestly, test whatever you get *before* you're relying on it for a shoot. Good luck!
