The Rokkor is, as I recall, a bit smaller, but not by much. They are fairly close in size. I think the Rokkor is a bit lighter. If you leave you lens hoods on your lenses, the Summicron takes up more room in a bag since its hood is not collapsible like the Rokkor. The 40/2.0 brings up the 50mm frames. On my M4-2, I can position the frame selector lever in between the 35mm and 50mm position, showing both frames at once. When I'm shooting fast, I just make sure the important stuff is withing the 50mm frame. When I'm being more leisurely, I'll jiggle the frame selector lever and compose for about midway between the 35mm and 50mm frames. The focusing helical issue Jem mentions is not an issue if you're looking at an M-Rokkor, developed for the Minolta CLE, which has the same focusing helical/cam as a standard M-mount Leica lens. The M-Rokkors (28/2.8, 40/2.0 and 90/4.0) are multi-coated and utilize the Leica-M helical/cam. They have serial numbers on the lens barrel rather than the front element retaining ring, if you need help identifying which version you're looking at. Lots more info is available on Stephen Gandy's CameraQuest site.
