Laowa 28mm f/1.2 Argus review by SonyAlphaBlog: You either hate it or love it
Laowa 28mm at BHphoto and Amazon US&EU.
SonyAlphaBlog tested the fastest 28mm FF lens you can buy and concluded:
The Laowa 28mm F1.2 (750 euros) is the fastest 28mm available in the market. Like all extreme lenses F0.95/F1.2) comprises have been made to favour aesthetic over classical rendering.
The lens is very well built but is fully manual. A switch allow to have a clickless aperture ring for video
The sharpness is good wide open in the centre with a nice soft background blur at 50cm and a good color rendering. unfortunately the corners are quite bad and the lens suffers from strong field curvature, high vignetting and low resistance to flare. Also the bokeh at long distance is uneven : soft in the centre and quite busy in the corners due to the field curvature.
You like it for its character and unique rendering or you hate it
