Again at infinity, the coverage of a 105 mm (Nikkor, obviously) lens corresponds very closely to the -> 90 mm <- framelines. The lenses in question: 90 mm f/4 M-Rokkor, designed originally for the Minolta CLE, but with a standard M Leica mount and focusing cam. It is extremely compact and light (weight is almost identical to that of my 50/2 Summicron), and at infinity and f/8 or so, the results are terrific. This will be my standard take-along landscape lens. The only problem is that filters in the 40.5 mm size are difficult to come by. 105 mm f/2.5 Nikkor in Leica thread mount. A monster: about the size and weight of a 90/2 Summicron, with its own tripod mount. But as a portrait lens... Hoo, boy. Lovely definition even at close to minimum focus, and the background just melts. I have not yet tried it out for landscapes, but it would probably need to be used on a tripod. - -- Nick NICHOLAS HARTMANN hartmann@interaccess.com Oak Park, IL USA 73057.724@compuserve.com Technical and scientific translator: German, French, Italian -> English
