Sony announced a pair of short telephoto prime lenses at this year’s WPPI show in Las Vegas – the FE 100mm F2.8 STF GM OSS and the FE 85mm F1.8, both intended for use on the company’s a7-series mirrorless interchangeable lens cameras.

Hands-on with Sony 100mm F2.8 STF G Master and FE 85mm F1.8 lenses

Here’s the FE 100mm F2.8 STF GM OSS, which joins Sony’s growing ‘G Master’ lineup, as one of the company’s flagship lenses.

The 100mm F2.8 has a complex optical design, featuring 14 elements in 10 groups, including ED and aspherical elements. Somewhat unusually, this lens is a ‘Smooth Trans Focus’ (STF) design, which incorporates an APD (apodization) element. The APD element acts as a radial gradient filter, which – in simple terms – improves the quality of out of focus areas, by diffusing bokeh circles. Traditionally, we’ve seen APD elements in lenses specifically aimed at portraiture, for obvious reasons.
