Sony 70-400mm review: one of the sharpest super-zooms for wild life photographyBy Kevin Carter - Tuesday May 07 2013 Lens Review
Announced only in February this year alongside the Sony made Zeiss branded 50mm f/1.4 ZA SSM, the 70-400mm F4-5.6 G SSM II lens is an upgrade to the original silver finish model introduced in 2009. This new lens is said to boast up to 4x increase in AF operation and an improved optical performance (not to mention a new white exterior). Read on to see how well it performs in our labs.
Although this lens doesn’t bear the high-end Zeiss logo, this is a G-series lens indicating that the 70-400mm F4-5.6 G SSM II is a premium quality model for professional and advanced amateur use, much like Canon’s L-series. While it’s a full frame lens with a tempting range of focal lengths, it is more likely to appeal to users of the firm’s APS-C SLT cameras where it’s the equivalent of a 105-600mm. As a result, this is a very promising lens for wildlife photographers.
