I just got the 56mm the other day. I have only been out at night since then, but here are a few of my first shots. It's very sharp wide open and AF is convenient but it has disappointingly high levels of pincushion distortion.

Did somebody say pincushion?

I don't see any lens corrections for this lens in Canon DPP 4, but other software can correct pincushion distortion, including the free irfranview for the PC with all its plugins (perspective corrections but you do it manually). Distortion was apparently the compromise Sigma made on this lens to keep great sharpness in the corners at such a fast aperture, which is understandable as distortion is one of the easiest aberrations to correct.

I use DxO PhotoLab 5 which has an excellent set of corrections for the Sigma lenses and make the corrections totally transparent to you. If you are not familiar with this software, they have a free trial for 30 days. DxO has industry-leading de-noise which will allow you to reduce the grain to levels which will just preserve enough detail up to very high ISOs of 6400 and beyond - see my high ISO images posted here with the M6ii of the night trains. I have an M50ii as well (which produces images like those of the M50) and it does almost as well, lagging behind about 2/3 - 1 EV with noise level compared to the M6ii.
