As most of you know, I live at an altitude of 1 mile, which is more than 5000 feet but less than 6000 feet and about 400 feet below 2000 meters. My questions are these. Heering states that yellow filters are useless above 2000 meters and UV filters should be used. I do not have a UV filter for my SL66. Can I use the R1.5 to keep out the UV and achieve the same effect? Are Carl Zeiss lenses designed to keep out UV? Mine are about 1970 vintage. Do Leica lenses need UV filters above 2000 meters? Best of Light, Chris
