Sorry. I was thinking in Australian dollars. 256Gb card is 500-600 AUD.
MSY have a Sandisk 128GB UHS-II for AUD279 which is the cheapest I can find. The CFe cards are really expensive in comparison. If you find something cheap(ish) then let me know. I do know that CFe card readers are mostly out of stock especially the dual prograde CFe/UHS-II around the world.
On top of this, we still don't know what CFe cards are approved by Canon for the R5. The Sandisk USH-II is the fastest available and would be fine. The Sandisk CFe 128GB is not approved for the 1DXiii

Yes, but my point is that I doubt the 16 bit will allow you to exposure more to the right.

Dynamic range is difference between the brightest and darkest tones, it's not affected by how far you can expose to the right, as long as you don't overexpose.
Digital sensors generate noise most visible in the shadows and the noise hides the darkest shadows which reduces the dynamic range. So the DR battle is all in the shadows.

At the risk of reopening an old debate, in photography we capture images. Unless you're cropping to a single pixel, I don't really see the relevance of measuring anything on that basis.

In all popular measurements (photonstophotos, dxo) the pixel-level noise is actually the starting point. You're dealing with the pixel-level noise when you use the whole of your image before downscaling, not when you crop it to a single pixel.

And what practical knowledge is the measurement from a single pixel?

It might happen to be not fine btw, of you intend to shoot video on it, as it doesn't have a V rating.
This guy in turn has a V90 rating

Without a V rating, as far as I understand, it's not guaranteed to have consistent write speed.

While I'm not a Sony shooter, know quite a few that are very happy with theirs.

This doesn't appeal to me, but wouldn't call it trash.


Yea the brand bashing no matter who it is pointed at frustrates and boggles the mind. Anyone objective can see all these brands are making amazing tools that enable us to do incredible things that would have been impossible or very, very expensive just a couple years ago. The competition and innovation is good. The compromises each product makes are good and necessary, and keep the technology evolving. Nearly every camera I have seen has lots of pros and cons. I have seen no perfect cameras and no absolutely bad cameras for years.

If anything is trash, it is people's attitudes about everything.

Well, my 1DXiii has been shooting on that card since I received it and I have had zero issues. So far. The CFe card that is. I couldn't tell in your post when you were referring to the CFExpress or the SD UHS-II.
The CFe card. See the following link under "Possible Maximum Burst Rate...." is the table. The Sandisk 512B card is support but not 128GB even though it has 1200MB/s max write speed. I'm assuming that 5.5k60 raw in 1DXiii is similar bit rate as 8k30 raw in the R5

Well that is surprising for Sandisk! Which UHS-II cards are then supported? The CFe speeds are not clear to me but I thought the UHS-II supported 4k/30 continuous video at least. UHS-I cards have been used for 4K recording in the past haven't they? If I do higher video then I will use the CFe card.

There was a compatibility sheet from Canon, but sadly I lost the link and cannot find it now. I think the link was somewhere on this forum. Basically V90 should do even for non-raw 8K. The Sandisk SD above has a decent speed but it looks like without the V rating it's not guaranteed to be consistent, so there may (or may not) be issues with video recording.
I ordered this beast from Amazon and will live with it for a while, new covid restrictions have been imposed here in Victoria after I preordered the R5 so I won't be able to do a lot of photography anyway. Later on I'll figure what CFexpress card to get. Probably a SanDisk as above, and it should be at least 256Gb.
