55 mm filter threads

Some focus breathing
|comment:||A very nice looking copy with both caps and hood and original box and packaging purchased from KEH. This seems to have been the late Minolta mid-range kit lens with the non-D 35-80 II continuing for the cheapest models. "MALAYSIA"|
This lens is just slightly larger than the similar looking 35-80mm F4-5.6 II but smaller and lighter than the 28-100 D. It has a double-trombone style extending barrel where the smaller barrel extends for focus, and the outer barrel extends and contracts for the zoom mechanism. The decoupling of the two motions seems to have resulted in a kit lens that doesn't shift focus much at all with zoom.
Just like the 35-80 II and 28-100(D) kit lenses it is most contracted at 50 mm. It seems to be more closely related to the 1993 28-80 F4-5.6 than the other 28-80 lenses.
F4 30 to 35 mm
F4.5 35 to 40 mm
F5 40 to 55 mm
Overall image quality is very good at 28 mm even wide-open. The Minolta AF 35-70 F4 and 35-80 II perform better over their range, but are pretty similar at 35 mm. This lens is actually quite sharp at 80 mm. Sharpness and consistency across the APS-C frame are both very good throughout the zoom range, but heavy purple fringing and haze muddy high contrast images at the longer focal lengths. Other than purple fringing there is very little visible CA.
Apart from the printed lettering, the little circular hood is identical to the ones used on the 28-100 D, 18-70, and 18-55 lenses. The filter threads rotate preventing the use of a nice petal hood like that used on the manual zoom 28-105 F3.5-4.5 lenses.
Overall a nice sample of this underrated little lens. It may not be as brilliant as the 35-xx kit zooms, but the image quality holds up well compared to the more expensive F3.5-4.5 lenses. The minimization of focus shift with zoom motion makes this a very nice cheap zoom for video.
