surprisingly as sharp as the Sigma 24mm and 34mm f/1.4 ART primes and even surpasses the optical performance of both in the APS-C/DX-corner lagging a bit only in the FF/FX-corner at 35mm
quite a smooth Bokeh and relatively little longitudinal CA and moderate coma at f2.0
AF needed fine-tuning in Sigma’s USB-dock
