The Sony GM 100 STF is a somewhat specialized tool. I would not recommend it as the only lens for portraits as its lack of light transmission limits its use to pretty good light or on a tripod at slower shutter speeds.

The FE Macro 2.8/90 G OSS is the best lens from Sony I have reviewed so far. Optically there is a lot to appreciate: Sharpness is excellent in any scenario, CA very well corrected, there is very little distortion and bokeh is really smooth.
The Sony FE 4/70-200 is a jack of many trades but a master of none. For most applications the sharpness is very good, only the corners are a bit softer but still good enough for most applications.
The FE 1.8/85 delivers what I have hoped and expected. I see very good sharpness already wide open in the center and outstanding sharpness when stopped down to f2.8 across the whole frame as well as no distortion at all.
This zoom lens can keep up optically with many of the best prime lenses in every regard except of speed and flare resistance.
To round things up: this lens has hardly a negative aspect that stands out, which is something that rarely occurs.
