Pros: Sharp wide open, decent build(better than Canon), nice bokeh
Cons:
A little soft around MFD, warmer color(may not be a problem)

I jumped on this lens after doing research online for many weeks. Finally I decided to part with my Canon 50/1.4 and give this Sigma a try. So far I'm pretty happy with the switch. I feel my Sigma is slightly sharper than my Canon from f/1.4-2.0 though Canon is not bad at all within this range. As I'm a picky person on image sharpness, before I always used my Canon at f/2.0. Now I find myself use my Sigma at f/1.6 most of time happily.

The AF is pretty good most of time. The only problem I noticed is the images around MFD look a little soft sometimes, but not all the time. As I haven't done any extensive testing, I'm not sure if this is caused by the infamous AF issue or just some accident.

Color from this lens tends to be a little warmer(yellowish), which is not a big deal and can be fixed easily in photoshop. Bokeh is a big advantage over Canon. It's smooth and silky, better than Canon's. Overall, it's a very good purchase if you're a normal lens person and don't have over $1,000 for 50L.

Pros: Light weight, very sharp, rich color and contrast.
Cons:
Not any considering its performance and price.

My first L lens. Though I don't use it very often (I like bokeh from my prime lens better), it always makes me amazed whenever there's a chance I need to pull it out.

First of all, it's very sharp. Probably sharper than my prime lenses at the same apertures(85/1.8 and 50/1.4). Every time I was pixel peeping, I'd be glad to see those very rich and clear details. Color and contrast are also its strength, I feel it's slightly better than my non-L primes. But those things most of time would be determined by lighting conditions.

The only thing I wish it'd have is nicer bokeh which requires a larger aperture of course. But people need extra money to pay for that. For this price, it's a super great lens.
