Upgraded from the 50mm 1.4. Love love love this lens. Pictures are always sharp unlike the 50mm 1.4 which is very soft at 1.4 to 1.8. A Necessary evil I shoot a wide variety of subject matter for my work and, because I exclusively use full frame Canon bodies and always try to use prime lenses, a...

Pros: Durable, Fast / accurate auto-focus, Strong Construction, Consistent Output Cons: Other thoughts: I bought this lens for portrait photos mainly, I love this lens,it gives beautiful results, I borrowed a sigma 1.4 50mm prime lens from a friendbefore purchasing this one and the canon is a bit...

I'm a professional wedding/portrait photographer and a prime lens shooter. This lens was worth the upgrade from the 1.4. It's quiet and fast! Worth every penny.

Just got this a few days ago and am enjoying it, it's quite heavy, but feels well put together and very solid. Optically it produces great results. Bought it with 20% off so made it very competitive and interest free over 12 months. Delivered as stated and well packed.

Bit out of my comfort zone with a prime lens for weddngs but I thought I'd try the 50mm 1.2 out and oh how impressed I was and glad I've got a prime lens - still got a couple of zoom L lenses and they have their place for weddings, especially the 24-105L.

The background blur is the best
