Samyang 16mm f/2.0 ED AS UMC CS Lens for Sony NEX - BRAND NEW review
The Samyang 16 mm f/2.0 ED AS UMC CS is a really well-made construction. For a very sensible price of 1500 PLN you get a lens with interesting parameters, able to provide a sharp image across the frame, correcting most of optical aberrations in a proper way.
excellent image quality in the frame centre,, good image quality on the edge of the frame,, slight chromatic aberration – both lateral and longitudinal,, good correction of spherical aberration,, negligible astigmatism,, advantageous price/quality and price/ability ratios.
weak performance against bright light,, distinct vignetting at the maximum relative aperture.
