Hello forum members,
I have a 24-105mm f/4.0 L that has been giving me headaches for some time now.
It simply won't produce sharp images at 24mm for any object further than 200ft away.
I've had it sent to Canon twice already. Once they did nothing and once they "adjusted" my camera's autofocus settings.
It is not the autofocus. I've tried focussing manually to no avail. I dont care about the distance reading in the window on the lens barrel. I don't care if the lens is parfocal or not. At 24mm it does not focus on anything beyond 200ft away .
I made manually focussed image series slowly changing the focus distance and it looks like I just cannot turn the focus ring far enough towards infinity. The pictures get gradually sharper, but before I hit a good focus the ring hits the mechanical limit.
I've gotten rather frustrated about this to the point where I'm about to open the lens up myself (probably a terrible idea). Does anyone have any suggestions? I'm based in Northern New Mexico. Does anyon know a knowledgable repair shop the can recommend?
