attan said:a bit off tangent to the subject, cos i intend to get an m7 and it will be my first leica. do one put a filter in front of the lens. considering that the optics is excellent, would putting a filter negates it.
thanks for any advise
Whether Leica or not, it is just a camera and the lens is just a lens. Putting on a filter is a matter of preference or for the effects. If you're concerned about affecting the optics(that's if you can detect the difference), then don't put one.
