Panasonic Leica DG Summilux 12mm F/1.4 Asph Lens - BRAND NEW review
It’s worth emphasizing the fact that full frame 1.4/24 lenses are not only more difficult to design but also, unlike the Panasonic, their optics is responsible for distortion correction without any help from camera’s software.
Solid, metal casing,, Very good image quality in the frame centre,, Sensible image quality on the edge of the frame (meaning values averaged out),, Negligible lateral chromatic aberration,, Quick decrease of vignetting on stopping down the aperture,, Silent, quick, and efficient autofocus.
Distinct difference in sharpness between left and right sides of the frame,, Problems with longitudinal chromatic aberration,, Bothersome coma in the right part of the frame,, High distortion for RAW files,, Performance against bright light could have been better.
