The Canon EF-mount MF 85mm f/1.4 WS Mk2 Lens from Samyang is characterized by its fast f/1.4 maximum aperture to suit working in low-light conditions and for controlling depth of field. The optical design incorporates one hybrid aspherical element that helps to reduce distortion and spherical aberrations for a high degree of sharpness and accurate rendering. The manual focus design permits working with subjects as close as 3.6' away and a rounded nine-blade diaphragm contributes a pleasing bokeh quality. Fast f/1.4 maximum aperture offers a high degree of control over the depth of field for working with selective focus and shallow depth of field techniques. Additionally, it also benefits working in low-light conditions with shorter shutter speeds. Ultra Multi-Coating has been applied to individual elements to minimize ghosting and flare for increased contrast and color neutrality when working in strong lighting conditions. The aperture ring de-click function allows the aperture ring not to be stopped at every f-stop in the way cine lenses do. This selectable function will allow brightness to be adjusted continuously and smoothly with much more detail between stops. Weather-sealed design suits working in inclement weather conditions.
