|comment:||The second copy of this lens is much sharper than the first. The first was a beautiful looking early edition with crossed XX's. This lens is about the same size and weight as the Tamron SP 60 F2 Macro. It is much smaller than the older Vivitar Close Focus. On APS-C it acts like a 200 mm f/4 lens on full-frame. This was tied as the second cheapest Minolta AF lens when originally released in 1985. The original retail price was $140--the same as the 28 F2.8 and $35 cheaper than the 35-70 f/4. It now often sells for much more than those lenses. "JAPAN"|
During my initial testing of the first copy many of the manually-focused, tripod/delayed timer pictures were blurred in the center, but occasionally one in a sequence was sharp. After a thorough dis-assembly and cleaning the lens seems to be more consistent. It may have been a slightly sticky aperture causing the blur. The second copy is much sharper at least as sharp as the 55-300 though with much less CA control. It does have better CA control than the MD 135mm F3.5 at the same aperture setting.
This the first lens I have had that shows very little change in field-of-view while focusing. At close focus it acts much longer than the end of the internal focus zooms like the 18-135 SAM and 28-135. The angle-of-view is a bit wider than the unit focus MD 135mm F3.5.
The built-in plastic hood is rather undersized and doesn't lock into place like the one on the Minolta AF 50 F1.7 RS.
The second performs well enough wide-open to consider it superior to the best zooms. The heavy axial CA can still be a problem. A modern design with similar specifications would be a nice alternative to the larger, faster 135 mm offerings.
