A lens for all seasons

There's a reason 50mm lenses have sold well for large sensor cameras: this versatile focal length is equally strong for portraits, general photography and videos. When you've got one with an aperture this wide, you increase its utility tenfold. An f/1.8 aperture means fantastic shots in low light, and the "mild telephoto" focal length means portraits that will stand out against a buttery background blur.

Sony's outfitted this lens with smooth-running, near-silent motors: a linear motor controls the focus drive, and a stepping motor is the power behind the responsive aperture-control system. You'll appreciate the quiet operation the first time you use this lens to capture video with sound.

Crutchfield Customer Review (What's this?)

You can't beat this prime lens - creamy bokeh and sharp subjects, its the all-around can't-miss lens you've been looking for. Lightning quick autofocus, tank-like bulid... this lens absolutely has it all.

Pros: Creamy bokeh, great build, fast focus

Cons: Slightly more expensive than Canon and Nikon's offerings with the same specs...
