Excerpt: Very sharp. Great colors/contrast. The only thing I would have done different to this lens is put the focus hold button on the other side of the lens like the 85mm Zeiss is. It makes it difficult to use the hold button on the side they put it on.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Summary: Bought this instead of the kit 16-50 zoom for a Sony NEX-6, for the wider aperture, and as I am getting a 16mm pancake lens anyway.This is a very good lens, the bokeh from the 1.8 aperture is superb. Ive used it at both extremes of aperture, F1.8 and F22 and has given excellent results.
Summary: I bought this lens primarily for portrait photography and some video work. It is mounted to a Sony a99 and has been used on my old a700 as well. Starting with build quality: The plastics used are of a good quality and matted to the metal alpha mount.
Summary: I am trying to find equivalent lenses for switching from my mid-range Canon EOS-D environment to Sony NEX. I am a happy user of the SEL-P1650 and SEL-55210. All these lenses (the SEL-50F18 being the third) are good optical quality for my taste.
Summary: When I first bought this lens I was delighted: sharp, fast and a fantastically tight depth of field which makes for some creative photos. Since then I have bought the Carl Zeiss 135mm f1.8 which is fantastic and makes one a little picky.
Summary: I can't believe how much the price of these has come down. Mine was £300 used a couple of years ago, get one quickly before they go up again. First and foremost this is a very fast lens of course.
Summary: It may seem a bit expensive compared with Canon and Nikon 50mm primes, but the quality is great, and at F1.4 it is actually a very useful low-light/available-light standard lens. Great choice for social photography, parties, weddings, e.t.c.
