How bad is bad (lens scratch)?
Oct 31, 2021
Looking for a low cost wide angle workhorse, I have come across this venerable Canon 17-40 f4 L that unfortunately has a small scratch on the front element )-:
I figure that though this lens is not so young (neither am I) that does not necessarily mean it should go out in the garbage just yet (me neither) but am concerned about the scratch, so would appreciate any feedback you can provide on either (a) what you think about the image quality of this legacy lens compared to more modern wide angle lenses, and more importantly (b) the likely effect on an image made with a full frame camera of a scratch of this magnitude on the front element of the lens?
