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

[…] A compass is a nice bonus but I mainly just want to have the EXACT location data embedded into each file.[…]

If you’re in a place where there are no obstructions between the camera and the GPS/GLONAS/Baidu satellites, the position will still have an uncertainty of a meter, it gets worse with obstructions like foliage or your face pressed to the EVF So ‘exact’ needs to have some leeway

The GP-E2 had trouble keeping position lock while I was in a forest last week, my phone was a bit better, but that can cheat by asking the cell network for an approximation.

Around 30cm (1ft) precision can be attained by multi-band/frequency GNSS receivers. However, the receiving antenna in a camera is likely to be pretty poor*, so that will add to the inaccuracy.

Note: this is NOT the same as multi-constellation (GPS, Galileo, BeiDou, GLONAS) receivers.

*) An ideal GNSS antenna has exactly the same phase-delay of the signal, regardless of which direction or angle (attitude) the signal comes from. This is quite complicated to achieve and is the realm of large survey-grade antennas. These antennas costs hundreds if not thousands of (US) dollars.

You are kidding me, aren't you?! Get finally rid of those SD Cards, please!

Yet another disappointment from Canon, while others seem to have little to none heat dissipation problems.

If you don't mind being limited by 10gbit/s USB speeds: https://shop.progradedigital.com/pr...3-1-gen-2-single-slot-cfx-card-reader-pg-05-5

That reader works very well and it has a magnetic back, so sticks solidly to the side of a metal computer case..

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?

 

[Del Paso]

Your description fits a lot of politicians .

That's what I first wanted to add.
Yet, at second thought, I'd rather say that politicians usually know they are lying, especially the ones with strange haircuts.

When you say "others", what brands and model of cameras are you referring to? The tiny Sony's that overheat, the Fuji's that don't have the same internal raw/high frame rate video or the Sony/Fuji/Lumix cameras that also still use (-wait for it...) SD cards?

Get off your high horse and go Kickstart your own camera company if you're gonna be such a Negative Nancy.

Yup, I use the SD a lot as an in camera redundant backup. It almost never leaves the camera. I use the CF card to transfer images to computer then format it in camera when I put it back. The SD is of larger size SO I MAY GO ON 4-5 shoots before it fills up. By the time it does those images are backed up elsewhere and I format it, then start the process over again.

About two weeks out and the only added info to the rumor mill is it's "probably" going to have Type B/SD combo... Canon has apparently clogged all of its leaks.

Why?
I think its super handy. SD cards are everywhere availale. I dont need a cardreader on my notebook. I dont need a special card reader on my pc. Its cheap. And its fast enough (unless I have huge amounts of raws from a longer shooting like a wedding).
But for like 90% of photoshoots on the go I just use the SD card to copy the files, so I don't need to carry my cf card reader.

Also, i dont think heat got anything to do with this topic. I think a smaller card would be even worse, when it comes to managing heat...

 

[peters]

Not sure why this surprises anyone. Expecting dual CFE on a 5-series would be like expecting a version that was pink.

On my R3, I write raw files to both cards and usually use the SD card to pull the images off. Sure, the transfer speed is slower… But the overall process is faster since I can just stick the card in the slot on the side side of my MB Pro laptop or Stone Pro dock rather than having to dig out, connect, disconnect, and put away a dedicated card reader.

Thats exaclty my workflow on the R5.
Interesting enough, the Sandisk CFast Reader is not realy that reliable, it takes sometimes quite some time to get to card to read. The SD card reader in the macbook works very fast and reliable...
At home I use usualy the CFast Reader, since that is where I process the bigger jobs.

For video though I use only the CFast slot.
I think in that area of work a dual Cfast Slot would be great - to have full quality backups on a second card...

Couldn't they use both for both slots? Sony has this with Type A.

Having a pink Prosumer camera is absolutely the way to go. Canon is way behind in colouring their line up appropriately for modern times. All the other camera manufacturers have this already and personally this is an absolute no go.
If Canon doesn't come clean and give us a pink R5, I'm going to switch to Sony.

I've been using the FUJIFILM INSTAX MINI 12 Instant Film Camera in Blossom Pink since it was released. Not only is it lovely to look at, but it doesn't use CFexpress or SD cards, so it gets the prettiest photos. I've heard of photographers who prefer Lilac Purple, but I think they're crazy.

SD is ultra cheap

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

If you don't shoot video, I doubt you would see a big practical difference between v90 and v60.

Never heard of a "Black Body" haven't you?

Unfortunately, I haven't. After visiting Wikipedia, it's also unfortunate that I'll probably forget everything I just read.

CFa and SD are pretty much the same size, so Sony can do the dual slot thing. CFb and SD are different sizes, so wouldn't work

That's ok. The key point is that the concept applies after a system is at thermal equilibrium. Left unstated in the wikipedia article is that the black body will absorb much more heat and the thermal equilibrium will occur at a higher temperature than a white (or pink) body. It's nice that the black body will shed the heat faster, but it also heats up faster and to a higher temperature. There's a reason Canon decided put white paint on the supertele lenses with fluorite elements (which are more thermally sensitive than glass).

More evidence that a little knowledge can be a dangerous thing.

Thanks, neuro. I appreciate the added info.

Yes, Canon could use the same combined SD/CFe A slots but Canon wouldn't be able to record 8k30 raw (325 MB/s) due to the higher bandwidth required.

For some unknown reason, the A1 didn't receive any complaints that it didn't record 8k30 raw of any length of time.
Anecdotal reports have A1 shooters not worrying about CFe A cards as the only difference for still shooters is to clear the buffer faster.
The CFe A cards were initially only made by Sony, had small capacity and much more expensive than CFe B cards... let alone SD cards. After 3 years, there is more OEMs, higher capacity but still fairly expensive.
CFe A v4 standard has 2 PCIE lanes so can support faster sustained write speeds now.
