Guess the lens ...

A very good one.

Zeiss Loxia 21/2.8 mm...

Tamron 15-30 @ 24mm?

Zeis Milvus 21mm F2.8! 

Doesn't it look too go good to be true for u-wide?

Klaus, is the widest aperture of this lens 2.8, or this is just part of the chart?

Pana 30mm f2.8 macro?

Sony fe 90?

The aperture value starts at f/2.8, yes.

No hits so far ... ;-)

There are two missing Fujinon zooms (16-55 and 50-140) and both starting with f/2.8 but I rather think, that's a prime. Corners are too close to center performances for a zoom.
