The about $1499 Sony FE 100mm f/2.8 STF GM OSS is a curious beast.
I’ve taken my first look at how it behaves—off to Photoshop World tomorrow.
Includes images up to full resolution, from f/2.8 through f/11.
In EXIF data, the A7R II records f/5.6 for f/2.8, f/6.3 for f/4, and f/7.1 for f/5.6, which is confusing post-shot; one has to interpret in reverse to determine what was used. I deem this a bug because it corrupts the definition of f-stop vs T-stop. It also conflicts with Sony specifications: claim f/2.8 but record f/5.6? It’s not a good approach—let f-stop be f-stop and leave it at that.
