What are the alternatives to the sony fe 100mm f 2 8 stf gm oss?

The site doesn't list other lenses that fit the Sony FE 100mm f/2.8 STF GM OSS, so I can't name direct swaps from the catalogue. What I can offer is the reasoning behind it.

The STF's apodization filter gives very smooth out-of-focus backgrounds, but it costs light (T5.6). If you want a similar look with more light, look at the other lenses on my Portraits page. An 85mm f/1.8 gives a classic full-frame portrait view with soft backgrounds, and a 135mm or 70-200mm f/2.8 gives tight headshots with strong blur outdoors.

If you shoot APS-C, convert focal lengths first on the Focal length converter, since the same lens frames tighter on a smaller sensor.
