Never experienced this but on a shoot of mine the photos on my 85 prime produced warped/distorted images. Swapped out lenses so im assuming the camera body is fine since with other lens i did not have the issue. Shot at 1/250 on silent mode, camera body is Sony A7RIV. Couldn’t find anything on this and help is appreciated.
Image attached so yall can see what im talking about
I’m assuming this isn’t a cropped image… You have vignetting in the top right corner and not in the others… I’d say that you have a lens element that has decentred. A job for the service/repair people I think
