I Can't Access Videos from my Camera's SD Card

The thing is, Apple does what Apple does. Was it deliberate or a coding accident? We don’t know. And Apple is not known for fessing up with a mea culpa. If it’s a mistake it’ll mysteriously resolve itself in some future update. If it’s deliberate it never will.

You can send them feedback and let them know your thoughts on changing the feature

Product Feedback - Apple

I plugged in my camera card to the lightning SD reader and there was a short MP4 on there that the import function didn’t see. Which really just confirms what you are experiencing. The main difference is that my camera is a Canon and it sees subffolders, meaning the card is structured to have a DCIM folder then sub folders by month, then the photos/videos taken in that month. It sees the photos but not the video.

I had another card that had plain videos in a DCIM folder and it saw those, so seems to be a ‘video in a subfolder’ issue (as you noted)

after dealing with Apple for years my suggestion is...well find a work around either until it’s fixed or as a permanent way to get the functionality you want back. Let them know the issue via feedback, but it may be weeks/months/never before it’s fixed.

Probably your easiest solution could be to look and see if Sony has an app that may allow you to access those files.

Apple may or may. not tweak what their photos app and SD reader see.
