- Pentax K Mount Lens/Full-Frame Format
- Aperture Range: f/1.4 to f/22
- One Hybrid Aspherical Element
- Ultra Multi-Coating
An ideal portrait-length prime, the Pentax K mount 85mm f/1.4 AS IF UMC from Rokinon pairs a bright, fast f/1.4 maximum aperture with a short-telephoto focal length to suit portraiture and other applications where shallow depth of field is desired. This manual focus lens incorporates one hybrid aspherical element to control chromatic aberrations for increased clarity and even sharpness and illumination. An Ultra Multi-Coating has also been applied to lens elements to reduce lens flare and ghosting for increased contrast and color neutrality. This lens is also characterized by an internal focusing design, which maintains the overall length during use, as well as an 8-blade rounded diaphragm for a smooth bokeh quality.
