Minolta MC Zoom Rokkor 100-200mm f/5.6

Twist to focus, push or pull to zoom: one collar does both jobs on Minolta's MC Zoom Rokkor 100-200mm f/5.6, and after a roll or two your left hand stops thinking about it. That single control is most of this lens's personality. Everything else follows from the slow, fixed f/5.6 and the long, narrow barrel it lives in, built for someone who wanted 200mm on an SR-T without the bulk or the bill of a fast telephoto.

The design is older than the MC badge suggests. Minolta's lens data traces it to a 1965 Auto Zoom Rokkor, then lists this MC version from December 1972, an MD in August 1977 and a plain MD in May 1981, every one of them at eight elements in five groups. The 1965 original took 52 mm filters; the MC and MD versions take 55 mm. MC here means meter coupled, not multicoated. A coupling on the aperture ring tells an SR-T or XE where the aperture is set, so the body meters at full aperture. There is no MD tab, and the X-700 needs that tab for its program mode, so on that body you work in aperture priority or manual.

Eight elements in five groups is a modest count for a zoom, and the lens behaves like a careful mid-sixties design rather than a modern one. Plan on closing down a stop or two from f/5.6 for your best frames. Keep a hood on, too, since slow zooms of this era are generally more sensitive to stray light than the primes sold beside them. Closest focus is 2.5 m, which at 200mm gives you roughly a head-and-shoulders frame and nothing tighter. Flowers and insects need a close-up lens on the 55 mm thread, or a different lens.

The person who still reaches for it is usually shooting across a field in daylight. Picture a kid's football match from the touchline, where one pull on the collar takes you from the whole back line to a single player without your eye leaving the finder. The weakness is the weight hanging out front. Minolta lists the later MD at 570 g, and on an SR-T that mass sits well ahead of your hands, so slow shutter speeds turn into shake. The finder pays as well: at f/5.6 a microprism collar goes dark, and a split-image center stays readable only when your eye is square to the eyepiece.

Because the f-number holds from 100mm to 200mm, a Zone Light Meter reading taken at the short end is still right after you zoom to the long one, with none of the correction a variable-aperture zoom like the MD 35-105mm f/3.5-4.5 asks for at full aperture. Shutter speed is the number to watch. Under an ordinary overcast sky, ISO 100 film lands near 1/125 at f/5.6, too slow for most hands at 200mm, so load 400 or bring a monopod.

Used copies sell for very little now, a long way from the 43,000 yen Minolta's data lists for the 1977 MD version in Japan. Some carry the Celtic name instead of Rokkor; Celtic was Minolta's own budget line, and it sold this zoom in both MC and MD form. The obvious alternative is Minolta's 80-200mm f/4.5, which is two-thirds of a stop faster. Take the 100-200 when price matters more than that extra light and you can live with the length.
