Just got a RF 24-240 for travel and noticed when I shoot at max zoom w/ my R5 I frequently end up with a frame of digital artifacts surrounding the picture. It's only noticible in processing. I don't see it in-camera, either when shooting or reviewing. It also doesn't occur 100% of the time -- maybe 95%. And it's only at 240mm exactly. Aperture doesn't matter.

I don't see this with any of my other RF lenses so I'm sure it's not my camera. I know the RF 24-240 is a quirky lens at max wide, requiring s/w correction to remove harsh vignetting, but is this true at max zoom too? Is the "artifact frame" in my picture "normal" for this lens and assumed the user will crop it out?

Very simple to fix.

Enter into the Adobe ACR interface.

Find and open the "Geometry" menu at right.

Select "Constrain Crop".

The image will be cropped properly now.
