reviews

version I

version II

    • 1.4% barrel distortion
    • vignetting 3.3 EV
    • sharpest at f/4, soft edges at f/1.4-f/2.0
    • 1.15px lat. CA and considerable longitudinal CA
    • bokeh not great
    • “At max. aperture (f/1.4) the technical image quality isn't all that great - an extreme vignetting and soft corners are obvious flaws here” - best used at f/4-f/8
    • bokeh busy
    • lots of coma at f/1.4 much less at f/2.8-f/4
    • strong vignetting wide open, gone by f/2.8
    • good flare control
    • image gets slightly larger as focussed more closely
