They don't say this about most of the other Leica lenses, and I wonder what the distinction is. I have used filters with the Noctilux in situations where it was the only thing to do, like for example with Infrared Ektachrome. I didn't get many correctly focused shots that time, and I wonder if possibly the filter affects the focus accuracy with such a wide aperture lens. On an SLR with TTL focusing I don't think it wouldn't be an issue, but with a rangefinder it might be. I wonder if anyone who knows about filters and focusing errors could comment on this. Joe B.
