The Canon EOS R5 Mark II will continue with CFexpress Type B/SD UHS-II card slots

[Toamelicious]

I'm genuinely curious why people want dual CFExpress slots? I always throw a 512GB CF in there for RAW and record JPEG backups to a 256 SD card on all of my cameras. I've never ran out of storage on the 512. What is the realistic benefit of dual CFExpress slots for stills shooters?

Well because those people want fully redundant backups I guess.
Your system of Raw+jpeg provides a backup in case something goes wrong with the cfe card, but it isn't fully redundant, as you would have to use JPEGs in case of a primary card failure.

I don't have any cameras with those cards yet, so I cannot give any personal insights here, but I have definitely seen SD cards fail and was quite happy to have dual slots in my R6 and R7.

Weight may also be different, along with, as you mentioned before, megapixel vs noise.

Yea I think so, but for me who will always have a battery grip attached and no demand for cropping, if the noise is inferior to the R3 and maybe only the video aspect improved (maybe CF express 4.0), I likely will get the R3 instead, IME the 1 series body vs 5 series body have QC tolerance difference that specs alone don't tell

Sure but somehow I feel it's the heat issue, it's not like the heating from the processer and CMOS isn't enough, getting the CFe card in close proximity with high heat dissipation likely will lower the endurance of the card itself or at least lower the sustained write speed, IMO getting a SD card for CRaw provides enough redundancy already

I bet the heat dissipation will be better and maybe the EVF is better, but then a pro body vs a high end body is kind of no brainer if one will want a battery grip anyway

I think it's going to be an amazing camera for sure.

Hmm the EVF...I think the term "better" isn't referring to the resolution of the EVF (the R5 already ahs Canon's finest, shared with the R3) but that it's "better" because this one will swivel as per the recent patent announcement, "better" is relative.

The R5 is already a pro build. Since the release of the Eos 5DmkIII, the 5 series has had pro levels of build and it certainly shows compared to the Eos 5DII or 6D. However, the R6 & R6ii seemed to use the same ethos and now have the 5 Series level of build.
It makes sence because the R5 has become a halo camera for many professional photographers who need a pair of camera bodies and are better served with the R6. What we've seen is the R6 line has taken over the old 5D series use case scenario. This is partly due to cost of buying a pair of them and partly due to the fact that most pros don't often need the 45mp sensor.

For me, the R5ii is a "nice" have but it's not going to add much to my photography over my current R6ii and R8.
Sure the new stacked sensor will be nice, but the few times taht the rolling shutter has caused an issue for me, the R6ii's mechanical 12fps is more than I currently need. When i dial int he likelyhood of £4K UKP...hmmm I can get a pair of R6ii's for that and still have change.

IMO the features are not needed for most, I would like the stacked BSI CMOS for the faster readout + much better high ISO cleaniness, since I am still using the 5D mk III with a grip I am sure either camera will be a big upgrade, but BSI ISO cleaniness is what I really love to have. So since the price seems similar to the R5II and R3, and I don't have MP need over the 22 MP, I think the R3 would be the choice. only concern is I am wondering if the new R5 EVF have incoporated some changes that the R3 have been identified, like condensation inside when the outside is freezing and maybe in mild rain

I hope the readout is fast enough to use flash and the fully electronic shutter together, like the R3 can already do.

But looking at the prices of good and fast (!) CFexpress cards, I am really happy with my dual SD R6m2.

CF Express Type B cards are faster than fast SD cards.
Of course, you can get slower SD cards for cheaper but then you are not getting the full benefit of the cameras above the R50.

 

[EOS 4 Life]

I'm genuinely curious why people want dual CFExpress slots

V90 cards cost a fortune.

I always throw a 512GB CF in there for RAW and record JPEG backups to a 256 SD card on all of my cameras.

I work the same way but I still want a fast SD card to clear the buffer.

 

[EOS 4 Life]

slow SD is ultra cheap, the v90s are as expensive or more expensive than CFb

V90 cards are far more expensive than CF Express B.

 

[EOS 4 Life]

For some unknown reason, the A1 didn't receive any complaints

Sony good.
Canon bad.

 

[EOS 4 Life]

For stills shooters:
Adds the R3 eye controlled AF

I hope they also add it for video.
The R3 only has it for photos.

You should be correct about qc:
I can't remember anyone who posts regularly here having any series issues with R3 with the exception of the eye control feature not working for everyone. While there are some occasional posts about a problem with R5


Since you don't care about cropping, unless you are willing to spend the money on R1, it does seem reasonable to get a R3 while a sale is active either now or around the end of the year.

I'm used to cropping 30 MP pictures, taken with a 5D IV.
Even though its sensor is less detailed than the R3's 24 MP.
Unless you have to very heavily crop, like a tiny bird in flight, I don't see a real issue. Of course, it also depends on how much you plan to enlarge the picture.

Speed of clearing the buffer.
There R5 has a notoriously bad buffer and will get to the point where it will pause shooting until it clears.
Buffer clearing is a function of the slowest card type used.

There are some good articles on the fastest buffer clearing rates on the R3 using mixed vs. single cards and single CFE B is by far the fastest.
If the R5 II is giving 30 FPS and they haven't improved the buffer then this is a deal breaker for anyone shooting sports or wildlife.
Or you just have to shoot with a single CFE B card.

I have low expectations for the buffer clearing behaviour in the R5II. I would be happy to be proven wrong, though!

 

[DhlcadR6]

Using single CF B solves a lot of problems

I'm not sure how many people will agree but some say 35mm film is about equivalent to 20mp and many cropped back then....

While I have cropped like your example, it's not as fulfilling as getting close enough that cropping is only necessary for changing the composition. However it is often impossible to get closer...

It looks like the Canon EOS R5 Mark II will continue with the 5 series lineage and keep the fast card/SD card memory card configuration. So we’ll get a CFexpress Type B slot along with a UHS-II SD card slot. Starting with the Canon EOS 5D Mark III, Canon has used this configuration in all

See full article...

Still hoping there is a big surprise coming from Canon, without that I don't have a reason to upgrade. My hope was for double CF cards so I would have a duplicate of every shot without compromising the buffer. Other hope was to have a larger battery (even if in an add on grip) that supported the faster focus on the 400 & 600.

I crop on my 5D IV all the time to improve composition, and sometimes a lot. I find that Adobe's Super Resolution works pretty well in a lot of scenarios - I've definitely been guilty of cropping to like 12.5mp, then upscaling back to 50 using super resolution for printing, but that doesn't work well for some images. There's definitely nothing like having the resolution natively. I'm probably the only one out here hoping that the R5 has some options to pump that resolution up, like that old rumour on multi-resolution options. Definitely looking forward to some more rumours on sensor performance - come on 16 bit stills!

Well said.

Thank you, good sir. I gift you a bag of Cheetos!

Sure, more MP certainly can help. My next camera will be the R5 II. But my main motives are landscapes or macros, never sports.
Yet, it still doesn't mean you cannot take excellent pictures with 24 MP or even less.
So many award winning pictures have been taken with 24 MP, often more or less cropped.
