Such lenses as the Tokina 11–16 mm f/2.8 and the Sigma 10–20 mm f/3.5 raised the standards very high because both are very good instruments. Still we thought that the Samyang 2.8/10, being a fixed-focal lens with parameters not so far removed from those of the zooms, would be able to defeat the...
sensational image quality in the frame centre,, sensibly corrected chromatic aberration,, good correction of spherical aberration,, not especially high coma,, moderate astigmatism,, interesting parameters.
weak image quality on the edge of the frame,, too high distortion,, work against bright light should have been better,, distinct vignetting.
