reviews
-
superb optics that beat anything else in its class, reasonably sharp in the centre wide open, very sharp at f/2.8 but requires f/5.6 for highest levels of sharpness across the frame
impressive flare resistance
fast, silent, and accurate autofocus
excellent build quality
slightly fussy rendition of out-of-focus backgrounds under some conditions - ie.
bokeh may not be as nice as one would like
some vignetting up to 2EV in the corners at f/1.4, 1 EV at f/2.0 and 0.5EV at f/2.8
minimal barrel distortion of 0.8% on the long edge and 0.24% on the short edge
transmission T/1.5
