All my off topic SLR cameras all use very fast helix. >The slow focus for accuracy argument doesn't hold, it just confuses the eye. > > Jim I found a way round this that makes the Summilux much faster to use- I had a focusing lever made for me. It fits around the focusing ring of the lens and tightens with a small screw and has a little handle projecting about 1" so it is possible to focus it both quickly AND accurately. This lever is a little longer and narrower than that of the Summicron and to my mind is quicker in use. There is still a large focusing arc of course but it is now manageable in more or less one movement. Joe Berenbaum
