comment:I get now why Sony discontinued this lens in 2011. The overall softness of this lens may have been okay on a film camera. It is basically a cheap kit lens sharing a lot of design with the Minolta AF 50 f/1.7 RS. Giving it a 3.5 sharpness rating is generous, and it is only true for manual focus in the center of the frame.

The Minolta zooms have superior image quality at all aperture settings despite being slower, more complex lenses. The 28 f/2.8 prime does have a bit less distortion than the 28-105--very similar amount of distortion as the 24-85 zoom at 28mm. Sharpness across the frame is more consistent than the Sony DT 16-105 without the center sharpness of that lens. No real image improvement over the Sony DT 18-55 SAM II either.

The built-in plastic lens hood doesn't lock in firm enough to provide protection for the front element. The lens looks very well-built, except for that hood.
