For those sitting on the fence regarding using UV filters as lens protection:
Happened this morning....D40 with 35mm f1.8 lens sitting on my desk after cleaning, swiveled my desk chair to get up, and it caught the D40 strap, sending it down to the floor lens pointed down. Fell 30" onto the plastic chair pad over carpet, lens cap flew off, and the filter took the brunt of the impact.
Camera and 35mm lens OK, but the UV did not survive. I going to attempt to post my first pic on this site, but to describe the aftermath.....UV glass shattered, and the threaded portion of the brass ring partially separated from the exterior ring due to the impact. This is B&W's Pro thick brass exterior ring UV/haze 52mm filter, falling only 30".
I will stay with filters with exceptional glass protecting my lenses.
