Very bummed... :'( I was in NY last week and was about to head up to the top of the Empire State bldg for some great views after the rain. I put the 4x4 Tiffen filter over the anamorphic lens and then clipped it in with the binder clips (which I had done several time before). I decided it needed a little cleaning so I took it back out, cleaned it, and then fastened it back in but I guess I didn't do it well enough. It slipped out and landed on the sidewalk. I was very upset. I should have walked up and over 3 blocks to B&H and bought another one but I didn't realize how close they were. Oh well. Haven't looked at the footage yet but I'm sure it would have been crisper with the polarizer on. Can't cry over spilled milk (or spilled filter)... Myave I should invest in a Chrosziel Matte Box. I just don't want to add the extra weight to the camera or spend $1500.
