Ken Rockwell既評價:
The LEICA APO-SUMMICRON-M 90mm f/2 ASPH is the highest performance medium tele lens I've ever used. In fact, I've never used any lens with higher performance, regardless of focal length.
Why? The LEICA 90/2 APO is ridiculously sharp, even wide-open at f/2, and even in the farthest corners. Not only does it stay as sharp as the aperture is opened, it stays as sharp in the farthest corners.
枝90/2 APO 比起90mm f2 SUMMICRON-M版係sharp好多
唔比較還好,一泊埋2枝鏡就好大分別
