The Samyang AF 50mm f/1.4 EF II
is a fast and compact normal prime lens for Sony E-mount cameras. It
present several features that punch well above its class while still
maintaining a small and lightweight profile.
The bright f/1.4 maximum aperture pairs with a nine-blade diaphragm to
benefit selective focus and shallow depth of field imaging with smooth
bokeh, making it an ideal lens for portraiture. An Ultra Multi Coating
has been applied to lens elements to reduce flare and ghosting for
higher contrast and color fidelity. The optical design incorporates
three High Refractive, one Extra Low Dispersion, and two Aspherical
elements.
To compliment the imaging capabilities, the lens sports a customizable
focus ring that can be changed to perform other functions through
convenient switch located on the barrel. A Linear STM autofocus motor is
used to produce quick, smooth, and quiet performance with full-time
manual focus override, and a non-rotating filter, along with features
like Internal AF and reduced focus breathing make it an optimal lens for
video.
