Minolta AF 28-135mm f/4-4.5

Buy this used for the price of a nice dinner and you understand within a roll why nobody who owns one sells it. The 28-135mm has been a sleeper for thirty years, one of the most respected zooms in the whole Minolta AF catalog and still cheap because the badge does not pull the prices that Canon and Nikon glass does. It arrived in 1985 alongside the Maxxum 7000, the camera that put the first proper integrated autofocus SLR system in shooters' hands, and Minolta clearly meant it as a demonstration of what the new A mount could do.

The rendering is the reason. Wide open at f/4 it is already crisp in the center, and by f/8 the whole frame snaps tight in a way that genuinely outresolves zooms costing several times as much. Contrast runs high without going harsh. Color is that warm, slightly saturated Minolta signature people love in the brand's primes, which almost never survives into a zoom of this reach. The barrel matches the optics: real metal, real weight, a focus action that feels machined rather than molded.

The range carries the rest of the appeal. Twenty-eight through one thirty-five takes you from a wide street frame to a flattering short tele without a lens change, and there is a macro mode at the wide end that gets you into close-focus territory for flowers and detail work. It is the classic single-lens travel kit for someone who would rather not carry three primes. On an A-mount film body it does everything. Sony kept the same mount when it took over Minolta's camera line, so the lens drops straight onto a Sony A-mount DSLR with no adapter and keeps right on resolving, which is a large part of why it still changes hands.

The weaknesses are real and worth saying plainly. It is heavy and front-heavy. The screw-drive autofocus is slow and grinds audibly on modern bodies. There is visible barrel distortion at 28mm, some corner softness, and vignetting at the wide end wide open. Flare creeps in against the light if you leave the hood at home, and the early coatings were never designed for the reflections you get off a digital sensor, so backlit work needs care.

People cross-shop it against the Minolta 35-105mm and the later 24-105mm. Neither matches the bite of this optic at the long end, and both give up the brighter f/4 to f/4.5 finder that makes this one usable indoors. Different shooters will name the 28-70mm f/2.8 G or the 80-200mm f/2.8 G as their favorite Minolta zoom, and fair enough, but those cost real money and this one does not.

One practical note for the macro setting. Racked out to close focus, the effective aperture drops, so a meter reading off the scene reads a fraction of a stop optimistic. Dial in the close-focus compensation in Zone Light Meter so your near-distance highlights land where you metered them. The 72mm front thread takes standard ND and grad filters cleanly for slow water and bright skies.
