Summary: I recently used this one on a kid's birthday party. Shooting hyperactive kids is not easy. But when it's on spot, it gives me really good photos. I used it with an ND filter and mostly shot it wide open. I got really good portraits with creamy bokeh. Even sharper at f2.0/2.2.
Excerpt: Wow this is my first prime lens and first 1.4 fs lens. I really like being able to shoot in low light and shallow debt of field. It is easy to get images out of focus with such narrow debt of field. Example shooting child shoes, one shoe was two inches behind other show showed up as out of focus.
Pros: Fast / accurate auto-focus, Lightweight, Shallow Debt Of Field, Sharp
Excerpt: I've only been using this lens for a couple weeks but I've found very little to complain about so far. I've used several different fast fifties over the years and this one is about as good as any. In particular, it's much sharper wide open then most other lenses at similar apertures.
Excerpt: I was happily surprised to see this lens being so small and light. At f/1.4 it is a sweet and very fast lens. Great for low light situations. I do not have the 24-70mm lens, so I use this lens to fill in this range.
