NO! <------------------------------------ >If you do, do you see any difference in term of results ? Leica literature says any filter degrades the image. Especially in special light conditions. Unless it's bland front lighting, it's a special lighting condition. >If you don't, is the front element so sensitive ? NO, it's just big and front heavy. They don't want to replace it via passport if you drop it or it falls over on your tripod. But the filter would be smashed into the front lens surface anyway... I never used the UV filter. But I did use a polarizer. >BTW if you have any other comment about that lens, Very very sharp, I used it for several years, but sold it because of size and weight. It is BIG.
