A focal length that is perfect for portraiture and a range of other
subjects, a bright F1.8 maximum aperture, Optical SteadyShot ( OSS )
image stabilization and impressive image quality. Put it all together
in a lens that is surprisingly compact and lightweight and you have
a winning combination: the SEL50F18. The large maximum aperture
and Optical SteadyShot are worthy features in their own right, but
working together they make it possible to shoot crisp, clear images
under low-light conditions that would be beyond the capabilities of a
conventional lens. The F1.8 maximum aperture and a circular aperture
design also join forces to create gorgeous defocusing effects. Add
responsive, quiet autofocus and aperture operation, and you have a
lens that is ideally suited to shooting movies as well as stills.
