Small and blurry previews before import

[Michael37100666z6wl]

When I preview photos in LRC on memory card before import they are small and blurry with my new Canon R5 and R3. My old cameras showed full size and sharp previews.

Are you connecting the camera to the computer with a USB cable or are you inserting the memory card into a card reader?

Using a card reader. Thanks for responding

My thought is that the card reader is malfunctioning. What happens if you connect the camera to the computer with a USB cable.

Or, the camera card is malfunctioning. Try it with a different camera card.

I have tried 3 different card readers and have connected the camera
directly and still the same results. I have to zoom in 300% to get to
original size and image is not sharp. I import the image and it is fine.
Thanks for the response.

Typically, when any software previews un-imported images, it’s displaying the preview embedded with the raw file, not actually rendering the raw file. One way of diagnosing this is to check how the same raw files preview in other applications, such as:

• In the macOS Finder, using the QuickLook feature (select an image and choose the command File > QuickLook, or press the spacebar). 
• In Apple Photos, when previewing to import. 
• In Adobe Bridge, browsing the card with the Embedded preview option. 
• In Adobe Bridge, browsing the card with the command File > Get Photos from Camera (similar to Lightroom Classic import). 

If you see the same low resolution previews in all applications by any company, then the cameras might be set to generate and embed raw previews at low resolution. You can then see if you can change the preview resolution setting in the cameras. 

If you see high resolution previews in Apple apps but low resolution previews in Adobe apps, then maybe there is a problem with Adobe preview support for later CR3 raw files. 

If you see high resolution previews in Apple apps and Adobe Bridge (with embedded previews), but low resolution previews in Lightroom Classic Import, then maybe there is a problem in Lightroom Classic import only.

Basically, inspect these raw file previews from different angles (without rendering the raw file!), so that you can then use process-of-elimination troubleshooting on the previews.

Thanks for the help, I will try and get back. I feel it is something with
the new cameras because I never had this problem before.
