positive:Sharp across the frame wide open; constant aperture; solid enough for self-defense.
negative:Be sure to use that hood!
comment:I tested for sharpness as follows: I compared tripod shots at all focal lengths and apertures, looking at 100% on screen at an area one-third in from the left and bottom edges. I find my copy to be acceptably sharp wide open at all focal lengths except 210 mm. By "acceptably" I mean one can really only detect slight softness at 100%. All focal lengths except 210 mm were tack sharp by f/5.6.

At 210 mm, sharpness was acceptable at f/5.6 and tack sharp at f/8, a loss of only one stop over the rest of the range.

Color is first-rate Minolta: why we are here.

I got a screw-on ABS hood from Mennon, a big improvement over the included clip-on.

My copy has shown it to be worth its reputation. The only reason I would spend more is for faster or longer; for what it does it is a gem.
