Hi Matthias, how do you compare it with EF 50/1.4 ? Any noticable IQ
differences so far ? I thought this lens would be more popular for
nikon users where there's no comparable afs yet, so kind of surprised
to see first impressions over here ... and I found EF 50/1.4 to be
(already) very good.

The biggest difference, according to the dpr review, is the sharpness wide open (Lets say, between 1.4 and 2.2). From f 4 to 8, the situation turns, though, because the corners of the sigi sharpen up less stopped down. But other IQ parameters, like flare or vignetting, are also better controlled on the sigi.
