I keep clear B+W filters on all my Leica glass for protection. I add a 3 stop B+W ND filter that I stack on top of the clear filter if I want to shoot wide open during bright sunlight. and then i remove it when i head indoors or when the sun goes down.
I was in a local camera shop recently and the nice sales person was telling me that there are better filters that I should try that provide better sharpness, uv reduction and contrast improvement.
Any suggestions would be most helpful. I have 3 Leica lenses at the moment:
35mm lux, 50mm lux and a noctilux in case that helps.
Thanks in advance!
