I'm running Affinity Photo on Windows 7 x64. There is a problem with the ARW files of Sony A65 and A77M2.
Sigma 10-20 f3,5-5,6 lens is not correctly recognized and Tamron 17-50 f2,8 is not recognized at all, therefore automatic lens correction does not work.
As an alternative, I've tried using a dedicated PTLens program to correct lens distortion as a plugin, but it doesn't start
and Affinity Photo spontaneously shuts down. At the same time PTLens works correctly in Adobe PhotoShop and Corel PaintShop Pro.
