What reviewers say

Both tests value the compact size, quiet autofocus and sharpness when stopped down, while noting reduced contrast, soft corners and shading at f/1.4. The Digital Picture describes the wide-open image as soft and dreamy; Photozone finds very good central resolution. Both find good value and decent construction, though Photozone highlights out-of-focus fringing.
