Dan Havlik at Digital Photo Pro had the chance to interview Jeff Cable, probably the most talked-about Canon shooter at the Tokyo Olympic Games for his work with the Canon EOS R3.
Jeff gives a pretty glowing review of the Canon EOS R3 experience, but without the marketing speak, as there were a few things such as the eye-controlled AF that didn’t hit the mark all of the time.
Preorder: Canon EOS R3 Body
Q: How was the Eye Control Autofocus (AF) feature on the R3?
Jeff Cable: Eye Control worked well but there were some environments where it was more effective...

I have always been under the impression a RAW file includes an embedded jpg so there would be very little if any saving in shooting RAW to both cards.
I think the embedded jpeg is more compressed and presumably the jpegs he was writing to the second card were at the highest quality settings.

I guess you win and Canon's engineers are wondering why they didn't listen to the CR forum.
1 I have never questioned Canon engineers, nor do I now.
2 Engineers don't establish my needs.
3 Your answer is typical of a troll, no matter how many messages and age you have in CR.

I would think that there should be a few more positives about this camera besides eye control focus and simulated shutter sound...

Jeff has given us the reason to those who have argued that the R3 should have two CFexpress slots
He didn’t give it to us, that reason has been around since the 1DII that had CF and SD slots and launched two decades ago. Maybe it’s news to you, though.

I’ve never been a fan of dual media types in a camera, but that’s just an annoyance more than a physical limitation. I seldom shoot any of my cameras RAW+JPEG to both cards, but if that’s something you commonly do, then I can understand why it would be an issue for you. Overall, I think it was a mistake to do that mainly because of the performance limitation it imposes as well as the market the camera is in. If you came from a 1DX, Mark II or Mark III….well now you have to buy SD cards! If you’re coming from a Mark III then you probably already have CFExpress. Either way, you have enough money to buy a $100 64GB card or $175 for a 128GB if you plan to shoot just photos. Or you can splurge on the higher capacities. Heck, I remember a free CFast card used to come with the 1DX Mark II when it came out! I never got my damn free reader!!! Haha

Canon and other brands should just make us rip off the bandaid here…only the new format - and here’s why: I have now run into several people shooting the D850 who never bought a CFExpress card and just shoot with their camera as a single card because the readers are “too expensive” or they don’t want to buy them because they have SD cards already. So there is something to be said about people moving from one generation of camera to the next not adopting or investing in new media. It’s likely that some R3s will meet the same fate,but I feel like that’s a totally different market.

Oh well, this doesn’t bother me personally but I understand it will others. I use the dual cars more for utility and file organization with photos on one and video on the other…but it really would make more sense for this camera to have 2 of the same. I’m sure Tony Northrop is pumped to insert some old, slow, corrupted SD card into that slot and then claim the camera is terrible when shooting to 2 cards. LOL

My first (and only, so far) dual-slot camera was the 1D X, and I liked the fact that the slots are identical. I record RAW simultaneously to both cards as a failsafe, so I always have at least two copies of every image. Once an image is onto my MacBook Pro, within an hour it's backed up to a NAS with RAID 1, and within a week there's also an offsite backup on an HDD. Having said that, I've never lost any data to card or drive failure.

The bigger concern for me is the differential write speeds. But looking at Bryan/TDP's testing, the R6 can do 20 fps for 8.3 seconds writing RAW to dual SD cards, which equates to ~6 seconds on the R3. That's a much longer burst than I typically capture, so for me I don't think writing RAW to CFe+SD will be a problem. If it is, I can add the Image Copy command to MyMenu, shoot to the CFe only and duplicate the images to the SD card during down time.

Bet most wildlife shooters will pass on the R3. The 24 MP sensor is the deal killer. If it had 45 MP, it truly would be the do-all camera from portraits to BIF. Oh well, the R5 has been awesome.
Bet wildlife shooters that can afford the R3 will buy one. But I agree that most wildlife shooters will pass – because of the price tag not the MP count.

What was expressed was due to the amount of negative comments for maintaining that I would not buy this camera due to not having a double CF slot.
I know the story, I still have a canon with an FD mount and a 1dMkIII, with a CF and SD slot.

“Image copy command”!? Somehow I’ve never noticed that before. Is tha feature in all Canon pro and prosumer bodies? I have the R5.

I did not know that you could copy files from one card to another in camera using a Image Copy command in MyMenu. This is a great workaround where one captures RAW files to CFExpress and then backs up files as need. Thank you for pointing this out!!!
