Vignetting in corners of EF 24-105mm f/4L IS II USM

[miguelmarsh]

I have an EF 24-105mm f/4L IS II USM attached to my 5D Mark IV. When I'm zoomed in, I get vignetting in the corners of the image. Why? Is there something that I can do to avoid this? Thanks.

Hmm, sample of the problem?  Most of the time any vignetting can be corrected in post editing without notice. Just apply lens correction data. Your 5D4 might be able to correct it in camera.

The OP says they get vignetting when they zoom IN.  If that means towards the long end of the focal range (which is the normal one) why would one get vignetting at all?  It would be more likely at the 24mm end, i.e. zooming out.

Is the lens hood being used, or a screw-on filter?

This is common with many lens and as ebiggs notes, it is easily corrected via lens correction in post.  Canon DPP does a fine job of this and I am sure Photoshop does also but I do basic RAW conversion and lens optimizing in DPP before going to Adobe.

This isn't one of the Canon lenses I have used but a review states at the wide angle setting you lose about 1EV in the corners wide open decreasing to around 1/2EV as the focal length is increased.  Like most other lenses, the vignetting decreases as the aperture is narrowed.

Thank you, everyone, for your comments. You are right. I get the vignetting in the corners when I'm zoomed out (24mm), not in. It's strange. I just don't get it with my other lenses. Anyway, I will try the post editing that you suggested. Problem solved.

Ken Rockwell did see some at 24 mm, especially at f/4:
