優點:
Very good image sharpness, contrast and color rendition. Flare is not a problem. Light and fast focus.
缺點:
Huge lens hood, not a good range in 1.6X DSLR. Short zoom range.
評價:
An excellent film or full frame wide angle lens with very good to excellent image quality. Good for travel and well built. Image is surprisingly good even after adding PL filter for 10mm shots.
