>I recently bought a set of 109mm filters. I think they are Kodak and made for the aero ektars. I got red, yellow, orange, and "clear". I am wondering if the clear is actually a UV filter. Does anyone know of a way to test to tell UV glass from clear glass? TIA, JCO
Take pictures with it. Long distance, landscape shots. I once used a good UV filter on a SMC Pentax lens. Also took pictures without the filter. Big color shift, those with the filter removed the blue haze that often occurs in the distance. Other than that, no. Marnie aka Doe But I am pretty sure that is not what you meant. :-) I now put a UV filter on all my lenses. I shoot landscapes fairly often.
