Question re. filters

[Plato]

Thanks, all
Guess some folks have pretty strong feelings on to use/not to use. But I gather there is no distinction between filters made for film cameras and digital cameras--one made for one will work on the other? Subject to all the caveats listed, of course.

The only caution is the very old "linear polarizer." It works just fine as a polarizer but it will mess with the focus and exposure mechanisms in the camera (including late model film cameras). You want ONLY a "circular polarizer."
