My experience with 85, 90 and 105 mm lenses on Leica M bodies in portrait work has been good. One of my most used lenses now is a 90 mm Elmarit. I have just bought a 135 mm Hektor (chiefly because of low cost) and am wondering how that will be. The most obvious difficulty is the small V/F frame for that focal length -- which, in the M6 I now have, is just two lines. I shall appreciate the comments and advice of those who have experience of using 135 mm for portrait work with M Leicas.
