After updating to iOS 18.0.1, Photos on both my iPhone 15 Pro and my iPad Pro (11“, 2018) crashes when I try to import pictures from my Canon EOS R8.
The camera appears in the “devices” section in the app, the pictures start to appear, then the app crashes. The camera is connected via USB-C and this process has worked perfectly fine using the latest version of iOS 17.
Rebooting iPhone, iPad and camera did not solve the problem. And when using a relative‘s iPad Air, which is still on iOS 17, it still worked, so I suspect an iOS 18-specific problem.
I have not seen this myself, but thinking of one work-around you could try. If you have access to a card-reader, pop the card out of your camera and try importing the files that way. If your previously imported files are still opening correctly, it would indicate that the file format isn’t the culprit.
USB support in cameras has traditionally been a challenge, even if a modern camera like yours should implement the standard properly. Using a “dumb” reader could maybe solve your immediate issue, even if import might be at slower speeds.
The Photos app got a huge make-over, so it could be a newly introduced bug in there too.
Edit: Super anecdotal, but I just tried importing from my older Canon (5D Mk3) to Photos in 18.0.1 without any issue. Of course, USB2 speeds on the camera side and probably different CR2 files…
Thanks for the suggestion and for trying it out with your 5D Mk3! I don‘t have a card reader with me right now, so I cannot test ist at the moment. But I will try it once I have access to one.
I think it is be a newly introduced bug as importing both JPG and HIF (Canon‘s version of HEIF-pictures, used for HDR) worked fine before and I did not change anything else in the process besides updating to 18.0.1. I currently do not shoot RAW, so possible differences in the CR2 files should not be a problem as I don‘t have CR2 files on the card. But it is interesting that it works with your 5D.
I tried importing pictures using the SD card reader this morning, however it still did not work. I plugged the card into my Mac, copied the pictures using Finder, then put the card back in the camera and formatted it. I took a couple of test pictures and tried the import on the iPhone once again, and suddenly it worked fine. I have no idea what caused the problem (as it worked on the relative’s iPad on iOS 17, so it cannot be just an error on the card), but it seems to be fixed now.
So, if anyone else runs into this problem, use a Mac/PC/iOS 17 or earlier to make a backup of your data and then reformat the card.
