No idea, Markus... But I can see a number of things. The lens has a very friendly (smooth) bokeh character for its focal length (at least in this scene, but probably in general). It has a clear outlining in the OOF "disks". It clearly has no IS. And it is not super sharp, probably. I am guessing it is a relatively wide angle-ish lens, oddly hard to guess in this shot.
Is it by any chance your "close up fun" lens, the Sigma 20mm?

A large aperture wide ... that was my first thought when I saw the image.
I would put my money on the Sig 24/1.8 ... and I'm quite certain, that
its one of the 20/24/28 f1.8 tripple, that you atomized in the Nikon-FF-tests
not too long ago.
Just my uneducated guess ... Rainer

Sorry, no, it's not one of the Sigmas, it's not even a wide-angle lens. The equivalent focal length is in the short tele range (roughly 74mm in this shot).
Nice analysis, BC, including the conclusion that it doesn't have IS. It is, however, decently sharp, the blur in this shot comes from the leaf moving a little (probably induced by the lift-off of the fly) combined with a slightly too long shutter speed (1/40s, ISO was set to 100).
I also like the bokeh character. I definitely expected less.

24-85 VR? or maybe an old "cheap and nasty" kit zoom thrown in for fun, 28-105sumthing...
Something like a 70-200mm?
