There we were, in France, having successfully run the workshop, when we decided to visit Maison Blanche (near Brest). So, I put the 150mm lens on the camera, went back to the bag for the cable release, returned to the camera, knocked into it, and the lens jumped out of the front standard and did a nice double-bounce on the rocky shore! Of course it was my fault; I had put the lens in whilst stood behind the camera and not quite caught the board properly.
Fortunately, the only damage appears to be a couple of flat spots on the back threaded portion of the rear element. It doesn't seem to have affected sharpness or anything but I am one of those folks who don't like working with sub-standard gear. Has anyone any ideas how best to proceed with repairing such damage, if it can be (is worth geting it) repaired? Or is it really worth the expense if all seems OK at the moment?
Oh, and there's also the matter of the lens cap which is now residing somewhere at the bottom of a crevice between some rocks at Ploumanac'h... but that was Helen's fault
