Built, best glass in the world, accurate , fast and quiet focusing, amazing sharpness at all f-stops and zoom range, silky bokeh, practical range, attracts all sorts of attention just by carrying it around.

Even better, you can now rate this lens as a piece of working antique as the KM brand is now forever gone and "SONY" , although has re-badged this lens, will never be the same.

These are obvious:
1. weights like a machine gun
2. cost

It's hard to believe I am the first giving this super lens a review on this forum.
This lens I would argue is THE best lens in the entire Minolta lens range, if not, best lens amongst all brands.

Besides its very practical range, superb image quality and beautiful beautiful bokeh, this lens was built to last 200 years, to travel the world and to attract a lot of attention and praise "nice camera (they meant the lens), are you a pro?".
