Great filters

The filters work exactly as expected. Three of the four have virtually identical focus characteristics. The red filter is a little off from the rest, but I run an auto-focus with every filter switch anyway so it's a non-issue for me.

Completely unrelated to their use, I love how they reflect out-of-band colours back super cleanly. This is why the filters appear cyan/magenta/yellow in photos.
