A business partner of mine dropped our 70-200 f/2.8 mkI, and the lens is in bad shape.
There is a half-moon shaped series of cracks on the second element from the front (though you can't seem to see it in photos). The AF and MF, however, don't work above 135mm. If you try turning the MF ring at 135 through 200mm, the ring does nothing or almost nothing, rendering the lens quite unusable.
Does anyone have experience with damaged lenses? Does this sound like it's a write-off now, or is there hope?
I'm going to take it into the Camera Store this week, but it'd be good to hear your experiences.
Thanks and take care of your gear!
