I wonder if the lens is the 23f1.4; it is suppose to be super sharp and would have some field curvature (maybe?)

And already losing resolution past f2.8? Probably not that lens then?

To be resolved tomorrow ... or so.

Next to no CAs, BTW.

Well I still think it is one of 60f2.8 (sigma) 23f1.4 or 55-200 @ 55.

A final attempt: 55-250 IS STM 

Yeah, sure. ;-) 

No, it's a prime lens.

I give up.  :wacko:

Zeiss Apo Sonnar T* 135 mm f/2.0

Is it tomorrow yet ?

Depends on the time zone.  <_<
