Here are some Canon EOS R5 C specifications
- Thread starter Canon Rumors Guy
- Start date
SD Express will be externally physically backward compatible with other SD card formats but not speed wise (pin layout). If you put a USH-ii card (or UHS-iii card if they were available) in a SD Express slot, the max speed is UHS-i speed.
I have a brand new macbook Pro and the SD card slot is UHS-ii so your assertion is still in the medium term future.
Can you point to any available SD Express cards available in the market? There are a couple of announcements but no availability or pricing yet.

Canon could have put a UHS-iii slot in the R5 given the spec was released in 2017 but chose not to (or controllers were not available). Specs are one thing. Commercial reality is completely different. UHS-iii will be bypassed completely in my opinion. SD Express looks interesting but only backward compatible with UHS-i speeds ie UHS-ii cards are slow in a SD Express slot.

Depending on the availability of the R5c vs Z9's firmware update, Canon could be first to market with both 8k30 (R5) and 8k60 in a hybrid camera.
8k60 with a single battery would be even more impressive but I guess wouldn't have a significantly long record time and Canon are being conservative (for a change!). I wonder if Canon would define a grip (2 batteries) to be "external power".
Powering the external Tascam module would basically mean needing external power as well. Craig does mention a special wall power accessory which will be interesting to see

The latest Macbook Pro is not quite on the level of a gaming console and it's slot does not support the latest and fastest SD standards. It tops out at a paltry 312MB/s. Your other comment is true with any card and host. Even all CFexpress cards are not compatible with all host. Canon list compatible cards. Canon, Sony, and Nikon are on the SD express consortium. They are well aware of the future trends and manufacturing agreements. Any high speed cards can be used in UHS-I, UHS-II, UHS-III and SD Express host devices. Faster performance levels will only be attained when matching the card to the host device. Check out the new powerfull ASUS studio book and scroll down and see what card slot it comes with.

2021 MacBook Pro Models’ SD Card Reader Do Not Support the Latest and Faster UHS-III or SD Express Standard
Unfortunately, none of the 2021 MacBook Pro models support the UHS-III or SD Express standard, which may be a deal breaker?

Knowing Canon, I doubt. Why should they include a new chip supporting the forthcoming standard when using the current chip 1) costs less meaning more profit, 2) is less likely to suffer from supply chain issues, 3) using the new chip in the R5 II can drive upgrades, and 4) did I mention costs less meaning more profit?

~300MB/s is the current UHS-ii standard. I am not sure what you are referring to as there are no faster SD card media available. The macbook pro is one of the fastest PCs on the market especially on a per watt basis. It might not have video games released supporting that speed but to say that "gaming consoles" relate to having the fastest SD card slots in them seems strange to mention in a photography forum when no camera supports SD Express cards. Why would gaming consoles need fast SD cards?
Not quite true. UHS-iii and UHS-ii are backward compatible for all host/card but SD Express is not.
Correct. The R5 and 1DX (and I assume R3) will have minimum CFe write speeds needed to support burst and high bandwidth video recording. They are all using the same physical/electrical format though. No new controller is needed. CFe-Type C will never be released in my opinion
Video games have micro SD express slots, and new gaming laptops have SDexpress slots. Check out the slots on these new gaming consoles to be released this year in 2022. "Card Reader.....SDexpress"
I am not following your point here. Some new PCs have been announced (but not released) using SD Express slots. There is no media and they are not backward compatible with UHS-ii speeds.MSI Unveils New Gaming and Creator Laptop Lineup at CES 2022

I agree that SD Express is the logical solution to match CFe speeds but it will be some time (years?) before it makes sense to use it in camera bodies.
Sony uses CFe-Type A cards in 4 bodies but Sony is the only supplier and they are expensive and only small capacities. Canon would be crazy to use the dual SD/CFe-A slots with their main competitor as the only media source.
CFe-type B are years ahead of any competing formats. They run hot but nothing else comes close in performance.

There really is no reason like you stated to include something different on a platform that works and is making money. Those of us in the video industry whom use reds and arri from time to time deal with one card all the time. Card failures are becoming less and less prevalent and this is a nice way to keep people happy that don’t have cfexpress cards yet. People forget this is not a flagship. This might be a first and I think canon will blow many peoples minds tomorrow. I think it is incredible that they are even offering this.

SDExpress would be as hot termally as CFExpress if not worse.
This is spec, not implementation, and it accommodates the same single line PCI-E 3.0 and NVMe specs CFExpress cards use, but in a smaller form factor and with different pin layout, i.e. it may even use controllers and memory chips identical to ones in CFExpress cards, with probably even worse heat dissipation because of lesser card area.
We would need a next generation of controllers and memory chips with improved power and thermal characteristics, as Intel and AMD do for CPU, for example.

I would agree with you. An all plastic SD card housing vs the current CFe Type B metal would have very different thermal characteristics.

Does Canon usually allow consumers to preorder on the day of the announcement? Or do they do the announcement and specify a date for preorders to start? I can’t remember what happened with the R3 or R5.

With the R3, there was a development announcement by Canon in April, 2021 then the official launch announcement on 14-Sep. B&H began taking preorders at 6a ET on 14-Sep, and the first batch of R3's that shipped in November when to people who ordered by ~9a ET but later orders still have not been filled AFAIK.

Oh man. Released right at 12 EST. Scheduling error?well this guy released a video with all the details ahead of launch. including the price ($400 more than R5), and no IBIS

Incredible. This is an instant buy for me. For my purposes, having the R5 for photo/IBIS and the R5c for the cinema features will be the perfect combo.

As someone who shoots 85% stills for newspapers and magazines and needs a second camera as backup, I wonder if this could work out alongside the regular R5 instead of just having two of them...? Of course, the pricing will tell the truth eventually. I am shooting increasingly more video alongside shoots for web content.
