whatever you do, KEEP THAT LENS! Damaged equipment that still works can be the perfect touch to creating a certain atmosphere you may want later down the road. Don't throw it out. On yer next roll, take 4 or 5 shots with it, and shoot the rest normally. See what the results are. they may look REALLY bad, but hey, Antoonio's work always looks scratched up and dirty (well, not always, but some of it is), and are they not the shiznick, or what... hell, you may even wanna scratch it up summore!
