i had to use pliers and a screwdriver to remove my 50mm lens from my dslr tonight.
the lens wouldn’t come off after a quick swap at my niece’s concert. a quick search online revealed this happened more often than i would have imagined. for that, i am both happy and sad.
i used the guide here to remove my lens without damaging my camera: http://www.theroastedroot.net/removing-a-stuck-canon-50mm-f1-8-camera-lens/
fortunately, it is one of the cheaper lenses. i like my 50mm a lot. i will replace it, but i am leerly about having this happen with another canon lens.
