Sony FE 70-200mm F4 G OSS lens review: Classy contenderBy Kevin Carter - Friday April 04 2014 Lens Review
One of the four lenses announced at the time of the introduction of the Sony A7 and A7R, this high-grade G-series telephoto zoom looks like a promising addition to the range. Read on to find out how well it performs on the 36-Mpix Sony A7R.
The Sony FE 70-200mm f4 G OSS is the last model to be released of the initial four lenses announced specifically for the full-frame mirrorless 36-Mpix A7R and 24-Mpix A7 models. This is the first model in the system’s line up not made in-conjunction with Zeiss. However, as a G-series model it promises both high-grade construction and superior optical quality.
Like the other models in the line-up it’s intended for enthusiasts and has a complex optical construction consisting of a total of 21 elements in 15 groups and adopts both Super ED and ED glass as well as heavily contoured, molded aspherical lenses. The zoom also features the firm’s Nano AR coating for improved clarity and contrast and built in image stabilization but eschews the firm’s piezoelectric – sonic - type AF motor for a dual linear step-less type for smooth operation during video capture. Barrel-mounted focus-hold buttons and focus limiter functions, as well as a dust and moisture resistant construction add to the practicality of a lens like this.
Unsurprisingly as a FE-mount model it’s also compatible with the firm’s earlier APS-C format NEX models (and current Alpha mirrorless models) where it’s the equivalent to a 105-300mm. The lens has a fairly standard minimum focus distance of 39.3” (1m), adopts a 72mm filter thread and measures approx. 3.15 x 6.89" (80 x 175 mm) – roughly the same as similar spec’d models for FF DSLRs. Nor has Sony been able to make any real savings in weight, unfortunately, weighing in at 29.63 oz (840 g). The new lens is available for pre-order at $1,499, albeit including a removable tripod collar.
