Well I had a Russian colleague read the manual for me and he says no mention is made of them being necessary (and they aren't shown in the optical diagram therin). However, lots of other people (some claiming 'contacts' in the factory) have said they're necessary and since they miss the mirror fine on the LX, I have always used the lens with the clear one on. I'd love to get a definitive answer tho. > This could make a big difference in sharpness and another one in the > colour fringing. I can feel an experiment coming on... you know I have never done one! Chris
