User profile: Amateur
Cons: - not so sharp in the corners - some flare wide open - expensive
Pros: + really good sharpness in the centre wide open + stopped down better sharpness in the corners
Summary: this Sigma 1,4/20 lens is a really good performer fpr portrait shooting, but for landscape and architecture shootings you must stop it down, in order to increase sharpness of the edges my Fujinon lenses are much more sharper on my x-e1

Cons: very bulky, no filters
Pros: Ultra fast AF, awesome build quality, performance, creamy bokeh, close focus (27cm)
Summary: Just got it and tried few shots. I had to put +8 on the focus adjutment on my D610 but as my 50mm, the wide open sharpness is already crazy. The AF is not the quietest but blazing fast. I think it can go from min to max in less than 0.5 seconds. The size is to be considered hardly. I thought is would be larger but in fact, as the hood don't get off, it s pretty long too. It barely fits in my bag. Still, i need to test the field curvature.
