If you blink, Windows needs a reboot. One of the many reasons I moved away from Windows.

Would you like to interrupt your important project with pressing deadline with another mandatory forced update?

I updated Lightroom, Photoshop and Camera RAW today, downloaded a RAW file (CR3) from the DPReview gallery and tried to open it.

It still says "unsupported file".

DPreview files are corrupt. You can get R5 RAW files here. The samples tab have ISO examples.

By the way I have dibs on the snail. I already posted in the "I don't have an R5 yet but I'm posting a shot anyway" category".

Thanks a lot for the information!

RAW or C-RAW

Who’s doing what? Guess I don’t really understand the purpose except the file sizes are smaller.

Who is using C-RAW?

Not relevant maybe, but therapeutic

Raw file is smaller and takes up less network storage so I use it.

No noticeable difference in detail or in the shadows?

So basically it’s a compressed RAW file?

ZIP files are compressed using technology that doesn't lose even a byte of the original file. JPGs are also compressed, but they are "lossy." If you saved an image as a bitmap (not lossy) and compared it with a jpg, you could find pixels that are different.

It's my understanding that RAW files are compressed, but they have not lost any information. C-RAW is a lossy format to make smaller files. Thus you do lose information using C-RAW. But, like comparing a jpg to a bmp, the difference will be very hard (if not impossible) to see. I've heard that if you do something like underexpose by 4 stops and then push it in post-processing, the C-RAW has noticeably worse noise than the original RAW would have under the same conditions.

Alas, though, I have no R5 yet, so I can't confirm any of this...

There have been several that have done comparisons and no real noticeable difference at all in the raw.

I'm not doing C-raw yet, but I might look into it. One of the videos I watched explained that C-raw files make a difference in the buffer when shooting at high speed burst rates. I'm not worried about the R5 buffer filling up based on the way I shoot but if a smaller file will work just as well as a larger file I might just be interested.

One of my gripes about the EOS R and EOS R5 is that Canon doesn't give you the option to shoot smaller resolution images in raw. In the 5D Mk4 you could shoot:

30MP - raw
17MP - M-raw
7.5MP - S-raw


The EOS R5 will always shoot 45MP images if you shoot raw. Your only option is to use C-raw to limit the file size, but the image will still be 45MP.

You could use crop mode to reduce the file size.

Why is that a problem?

Currently thinking about switching back to a canon R5 from sony A7R3.

The only question i have at the moment that i can't find an answer for are:
does it do zebra striping in photo mode?
or Highlight Alert while shooting/live view

So that you can get highlight warning when using the viewfinder .
