Minolta MC Rokkor 85mm f/1.7

For years this was the cheapest way to put a fast, genuinely good 85 on a 35mm body. Minolta never marketed it the way Nikon pushed the 85mm f/1.8 or Canon pushed its FD glass, so the MC Rokkor 85mm f/1.7 spent decades in the bargain bin while doing the same job. Word got out eventually. Portrait shooters who came up on Minolta SR bodies, or who adapted Rokkors to mirrorless cameras in the 2010s, found a short telephoto that renders skin and separation as well as lenses costing three times more.

The optical signature is the reason people keep it. Wide open at f/1.7 the center is already excellent, with the corners tightening up from f/2.8 toward f/4, though they stay a touch soft even stopped down. Sharpness was never the headline anyway. The out-of-focus rendering is the selling point: smooth, rounded, no nervous edges, the kind of background falloff that sets a face cleanly off whatever is behind it. Color from the MC coatings runs slightly warm and a touch lower in contrast than modern multicoated glass, which on portraits reads as flattering rather than flat. Stop it down and the contrast firms right up.

It is a classic short-telephoto double-Gauss, six elements, and it behaves like one. That means a couple of honest caveats. Shot straight into a bright source it will throw veiling flare and the occasional ghost, because the multicoating of this era was less effective at suppressing flare than the deeper multilayer coatings that came later. A deep hood fixes most of it. The other limitation is purely mechanical: this is fully manual focus, no aperture coupling to anything modern, so on a digital body you are focusing by hand and metering stopped down or wide open by feel.

That manual nature is where it pairs naturally with a meter. Open to f/1.7 in a dim room, get your reading, then remember the lens does not report aperture to the camera. With Zone Light Meter you set the working aperture and shutter yourself and place the skin tones where you want them on the zone scale, which is exactly the kind of deliberate exposure this lens rewards. The 55mm filter thread is shared with several other Rokkor primes, so a warming or diffusion filter screws right on.

Today it sits in the affordable-classic tier, cross-shopped against the Canon FD 85mm f/1.8 and the Nikkor 85mm f/2, and it usually wins on price while holding its own on rendering. People still buy it because that warm, low-contrast portrait look costs a lot more in newer glass and these copies stay cheap. The catch is condition. These are fifty-year-old lenses, and a hazy or oily-aperture copy will rob you of the contrast that makes a clean one worth owning, so buy clean and you have a serious value buy from the manual-focus era.
