The "heavy" version is the first one, with a fixed tripod mount, using Series VIII filters, and a minimum focus distance of 4.5 meters. The second version uses E67 filters, has a rotating tripod mount, and focusses as close as 1.7 meters. The second version has three cams, the first version may have one, two or three cams. I have not used the old version. Optically, the second version is very flare-resistant and the performance in the center of the photo is good. Chromatic abberations in the outer areas of the picture reduce image sharpness. ------ Unsubscribe or change to/from Digest Mode at: http://www.lrflex.furnfeather.net/ Archives are at: //www.freelists.org/archives/leicareflex/
