The M-mount system boasts its compactness. Because it’s mechanically optimized to use with wide or normal lenses, one would hesitate to get a short telephoto lens. Yet, 85mm or 90mm is a main lens for portraits, so it’s not that you’re not interested in it even though you don’t have it. Another merit of using this focal length is that it can capture a time axis. With its moderate compression effect and narrower angle of view, it leads viewers to imagine the scenes before and after the shot. In short, it makes shots become picturesque easily. Let’s say, if you take streetsnaps just with a short telephoto, you first get puzzled because you’re used to 35mm to 50mm perspectives. But soon, you’ll feel how it is easy and fun to frame with it. It’s so easy that next you would have to fight with the temptation to take pictures in order to frame, rather than to frame in order to take pictures. It’s simply a waste to use wide and normal lenses only just because it’s a rangefinder. If you add a short telephoto lens, your approach may change even when you use wide and normal lenses. Because of the modest specs, the Tele-Tessar T* 4/85 is an excellent performer wide open and the price is more reachable. The bokeh is natural and above all things, it’s compact. If you hide it in your bag, your shooting will be even more exciting.
