test results have been added to the Sony FE 100mm f/2.8 STF GM OSS Lens
You are going to be impressed with these results.
This is a unique lens.
The product images
show that this lens has a manual aperture ring denoted "T", for T-stops, showing the actual amount of light transmission.
While this is technically an f/2.8 lens, the T-stop ring stops at f/5.6 and f/5.6 is the widest aperture selectable in-camera.
The reason has to do with the STF (Smooth Trans Focus) feature including an optical apodization lens element.
More information coming.
