I need an adapter to import photos from my camera to my 10,5 iPad Pro when I am away from my Mac. I just don't understand the difference between the USB 3 Camera Adapter and the SD Card Camera Reader. Of course, I know that the first will require my regular camera data cable while the latter can be used directly with the SD card. With the iPad Pro 10,5 and the latest versions of the adapters, transfer speeds should be the same (USB 3), right? And both support the same file formats? I see that user ratings of the adapters vary significantly depending on the website. Is there anything I didn't get? I know that the USB adapter could also be used to connect the iPad to, e.g., a microphone. This is not relevant for me. However, if one of the two adapters could be useful for other (future) use cases, this is an argument. Could the USB connector also be used to import photos from an iPhone to an iPad to create a backup? Thank you for your support!
