Sony 300mm f/2.8 G SSM II lens review: second update to pro-oriented G-series super-telephoto primeBy Kevin Carter - Monday July 01 2013 Lens Review
Sony 300mm F2.8 G II mounted on Sony SLT Alpha 99 Versus Canon EF 300mm f/2.8L IS II USM mounted on Canon EOS 5D Mark III:
When compared to the latest Canon EF 300mm f/2.8L IS II USM version fitted to a 22-Mpix Canon EOS 5D Mk III, the Sony 300mm f/2.8 G II combination doesn’t fare particularly well. While it can hold its own against the Canon in Transmission, Distortion and Vignetting (and CA for all intents and purposes), the Sony’s Sharpness score is discouragingly low compared to the Canon equivalent. Given the Sony SLT A99 has a slight advantage in pixel count over the Canon EOS 5D Mk III is only more revealing.In fact, with a Sharpness score of 22P-Mpix the new Canon lens can clearly out-resolve the best performing sensor in Canon’s range currently.
