Introduction | Sony E 20mm f/2.8 lens performance | Sony E 20mm f/2.8 vs. Nikon Coolpix A lens: lightweight, wide-angle primes battle it out | Conclusion

In summary the main advantages the Sony E 20mm f/2.8 lens has to offer are convenience thanks to its lightweight ‘pancake’ design, wide-angle field of view and ‘fast’ f/2.8 maximum aperture. Optically it’s far from perfect and although Sony have minimised chromatic aberration, sharpness score of 10 P-Mpix is too low for a lens mounted on a 24-megapixel sensor. Some minor barrel distortion is also evident too and lens shading at the maximum f/2.8 aperture requires correction in post-production. If it’s a small and portable high quality camera you require for street photography or photojournalism the Nikon Coolpix A boasts better image quality and value for money, but doesn’t offer the flexibility of the Sony NEX interchangeable lens system.
