The sample lens as is reviewed there:

Unfortunately mine is for Canon EOS system. Which older Sigmas stopped to work with digital EOS cameras.
However, when I obtained for my Sony Sigma mount converter MC-11, then I discovered that it generally works with that convertor. Only the AF is really awful. Completely useless. But for the wide angle lens it is not so critical.
And so, I decided to try is with my Sony A7s.

I have an earlier version (without "II") of this lens, albeit with a Minolta AF mount. This earlier version is a bit inferior to the (ten years older) Minolta MD-III / AF-I 2/28mm, and therefore I haven't used it much. Would be interesting to know the differences between the first and the second Sigma 1.8/28mm, though ... Differnt computations, or only slight improvements e. g. concerning AF??

Looks like it was the same optical design for both 9 elements in 8 groups

I was looking at bicycles. Chairs and shirt look good. But greens and blues are outstanding imho.
