With that out of the way, it does seem to sharpen up decently, and there's much less CA and better contrast.
The CA on the chair pic were due to black subject on almost white background under extremely bright sun. Any lens will give CA under these conditions.
But CA is the least of my worries. The build is. Although it might look like Sigma EX DG line, the upper part of the lens cup (with golden Samyang sticker) is made of a very fragile plastic, and can be easily broken. If you put on the hood which is also made of plastic, the chances of breaking this fragile construction are very high. Frankly I am not excited. Buying one of Cosina/Voigtlander Noktons is definitely a better idea. At least for their resale value.
I will try to take decent samples over the weekend both on digital camera and film (I was too busy today and practically had no time), but I am already inclined to get rid of it.
For those who complain of me not using the lens at 1.4 - I am in the Southern Hemisphere, in the middle of the summer with extremely bright sun always above your head. Not your ideal conditions to use it at 1.4. And for those who didn't understand who I am, I am the "person" from the Russian site who was stupid enough to buy this lens
