Upgraded AF motor In order to provide as fast, accurate and quiet autofocus as possible, Samyang has used its new, upgraded autofocus motor Dual LSM (Linear Supersonic Motor). Focusing also occurs internally, with just one single element being moved, which means that the length of the lens remains the same regardless of focus distance. If you prefer to focus manually, the lens has a wide and user friendly focus ring. The aperture is electronically controlled, which means that you can use all exposure and light metering modes the camera has to offer. A lens for attractive bokeh Samyang AF 85mm f/1.4 F may be small and light, but inside the weather sealed housing is 9 elements divided into 7 groups. The design includes a hybrid aspherical element that ensures maximum sharpness even at the largest apertures, which are commonly used in a lens for portrait photography. Samyang´s effective Ultra Multi Coating (UMC) ensures that the images always show high contrast and brilliance as well as neutral color reproduction. To reduce the risk of reflexes in strong side light, the user can mount an included lens hood. The aperture has 9 blades, which contribute to render out of focus areas in a soft and attractive way.
