Filter Ring and Circular Polarizer

Filter Ring and Circular Polarizer
I bought two filters, a decent CP and a cheap UV -- both of which had to be ordered online, since suddenly none of the electronics or camera stores in Denver carry 30mm filters. This is apparently a recent development, as I swear I saw them in stores as recently as a couple months ago when I started planning this project.

The glass in the UV filter was not desired, so I applied masking tape over the whole thing, stood it on a stack of quarters (so that the glass was in contact with the quarters and the ring was unsupported - so as not to put any load on the ring that might distort it), and broke the glass out with a hammer and nail set. The glass crushed into a mess of dust and sand-sized particles (which I did not expect), but came out as clean and easy as I could have hoped for, with no damage or distortion to the ring.
