quick focusing. Sharp, especially when closed down a stop or two. Seems rugged enough for a modern polycarbonate lens (polycarbonate is actually more dimesionally stable than metal under temperature extremes.

Posycarbonate lenses feel plasticky, and the focusing is a bit loose (because of the autofocus) making the thin manual focus ring a bit hard to use. A typical modern day lens. But the focus is accurate, so I guess it's OK for what it is.

A good fast 135mm autofocus lens. Intended for autofocus based on the thin, but still usable, manual focus ring.
