|comment:||My first copy was bought from a large eBay store for only $30. It looked in good shape but images were a little soft. The second copy came from a private Amazon seller for more than twice the price, but is much sharper.|
This lens was released a year after the original Minolta AF lineup. It was originally about twice the price of the 70-210 F4 and about the same price as the 28-135 F4-4.5. It looks nearly identical to the 70-210 f/4--I thought I had been shipped a 70-210 f/4 by mistake when I opened the box. "JAPAN"
It shows a little less lateral CA than the 55-300, and much less any of than the Minolta AF 70-210 lenses. However purple fringing is severe wide-open especially on the wide end. If there is going to be optical problems with a telephoto zoom it is probably better than exist on the wide end rather than the long end. It has a bit more reach than the 70-210 F/4 on a 1.4X teleconverter and much better image quality.
There seems to be a complex action in the zoom mechanism beyond 250 mm when the front and rear elements stop moving and just some internal element changes for the last bit of zoom.
At close focus the 75 mm end has a narrower field-of-view than the 70 mm end of the 70-210 F4. The 70-210 F4 reports 90 mm and the 35-105 reports 85 mm for this field-of-view.
AF works fully on the A65 with this lens when using any of my teleconveters including the 2X teleconverters. The A58 doesn't lock as well when using the 2X teleconverters. The CA is worse when using the teleconverters and the DT 55-300 is noticeably sharper in the center of the frame. The 100-400 APO is also much sharper than this lens on the 1.4X TC.
My second copy of this lens seems to match my DT 55-300 pretty well, except with an even flatter focus plane. So, if you don't mind the size and weight this can be a great budget option.
