Digital Camera World Verdict

This Sony prime certainly isn’t lacking in sharpness, but that’s not really the point. As a ‘smooth transition focus’ lens, it features an apodization filter to enhance the quality of bokeh. And it does so very well, at the usual expense of a drop in light transmittance at wide to medium aperture settings. Handling is very refined and there’s a neat close-up option. All in all, the lens works wonderfully well for portraiture and still life photography.

Think ‘100mm F2.8’ and you’re probably thinking of macro lenses. The Sony FE 100mm F2.8 STF G Master OSS is something different entirely. Sure, it does have a switchable close-up mode but its killer feature is its apodization filter, for smoothing the quality of bokeh. It’s certainly not unique in this, as similar internal filters which are like circular graduated density filters are used in other lenses including the Fujifilm 56mm F1.2 APD XF as a world-first and the more recent Canon RF 85mm F1.2L USM DS.
