New Viltrox 27mm f/1.2 Pro lens reviews
The lens is available at Amazon and BHphoto.
SonyAlphaBlog concluded:
The Viltrox 27mm F1.2 (600 euros) is another gem from Viltrox. Its unusual focal length (40mm equivalent) is a bit narrower than a 23mm (=35mm equivalent). It offers Excellent sharpness, bokeh balls , soft background blur , very good color rendition and very good AF. Note with the F1.2 aperture you will need sometimes to have a ND filter with the limitation of 1/4000 sec on A6xxx
Compared to the Sigma 23mm F1.4 DC DN, it is better balanced as the Sigma although a bit more sharper has more nervous background blur and more Chromatic aberrations
