comment:What a wonderful lens! Old-fashioned in the best spirit of the later 1970's/early 1980's traditional all-mechanical lenses. It is solidly made of metal and glass, but very compact in the way that so many fast AF lenses aren't. Lovely to handle and a pleasure to use.
It is amazingly sharp wide open, but like many fast lenses you pay the price for sharpness - at f1.4 expect lots of axial CA (red fringes in front, green behind) on high-contrast edges such as writing, plus some lateral CA too. I only took a few shots with this but it looked to have some strong curvature of field, and at f1.4 the DOF is so thin that this will show up with most subjects.
It cleans up as you stop down, naturally, but you'd want to use this wide open or near it, and when you do the CA is too strong to ignore. If I did more portraits I'd probably buy one and suffer the nuisance of correcting the CA in PP, but it's too much of a specialist lens for me, and most of the time a well-corrected sharp 90mm f2.8 macro AF lens will be more useful. Which is a pity, because I still like it!
MF doesn't bother me but I wish it had a ROM chip.
