Excerpt: This lens is sharp and light. This lens will be a walk around lens. I had the 35mm f1.8 G which I love but not convenient for portrait shots so I decided to get this one as well. I can't be happier.
Summary: This is an inexpensive lens that performs just as well as it more expensive counterpart, the 50mm f/1.4G. I use this mainly on a Nikon D5100 but it does see some action on my Nikon D800 as well. When used on the D5100, it is the equivalent of a 75mm focal length on a full-frame sensor.
