Sony a7r iv raw files on ipad pro

[kjd138]

I have just bought the Sony a7r iv and hoped to do some editing of the RAW images on an ipad pro using affinity photo. Not had any luck getting the raw files to show up. I understand that, using an SD card reader, that it is necessary to import into  apple Photos first. This only results in a grey image with no info showing up in Photos. If I attempt to import this into Affinity Photo a message comes up saying file not supported. Yet all the info in FAQ suggests that the a7r iv raw files are supported. What is going on?

Hi Kjd138,

We use Apples Core RAW engine on iPad and the files this supports changes depending on the version of iOS you have. Which version of iOS is it you are using?

I’m using iOS 13.3.1 on second generation iPad pro

It seems Joel Schaffer is having similar problems too, although with a different camera.

If your camera is on this list it will be supported, if not, hopefully in a future IOS update.

Edit: I see your camera looks to be supported but the evidence of your eyes is it isn’t. Might be worth reporting to Apple first since you mentioned Photos isn’t recognising it.
 

Just one thought, some cameras support some sort of additional compression, have you checked your camera settings to make sure no additional compression is being applied that might upset IOS reading the files correctly.

Thanks Paul: as you observed the camera is on the list  -  Sony Alpha ILCE-7R IV

I have selected uncompressed RAW.
