positive:Very very sharp. Even at long end and full open. At shorter focal lengths, it's even sharper...almost as sharp as the sharpest prime lenses I own like Minolta AF 50mm Macro and Vivitar S-1 90mm Macro (Bokina) (btw, both of these are ranked among the sharpest lenses ever built by any manufacturers at least up to year 2000.) Really amazing!

Bokeh is not bad for such a sharp lens either.

55mm at the short end is really useful. It doesn't sound a big difference from 70 or 75mm but in reality it DOES make a big difference.
negative:Blueish colour. This must suggest the improper coating, which is a bit surprising for a modern lens. What a shame! The original lens hood doesn't seem to be effective to cut the stray light. With it images get really blueish under the blue sky. So I use a narrower hood, but the images can still be blueish under some situations. They sometimes get blue/green fringing as well. 3 points in colour and flare reflect these issues.

SAM has no benefit at all. It makes the lens much fatter than older lenses of this class but AF speed is probably slower than traditional shaft drive AF. It sometimes resets the AF to the minimum focal distance. So next time it has to start from there and focus a long way to the actual distance which is most likely near the infinity. This is really annoying.
comment:Sharpness is really amazing. Bokeh is not bad either. The range starting from 55mm is very useful. It's light weight but fat. SAM has absolutely no benefit to the traditional AF. Blueish colour can be a problem but using a narrower lens hood helps here.

Overall this must be the best lens I have ever had in this range but I still miss my stolen Big Beercan which produced solid images more like those from a prime lens.
