Samyang MF 85mm F1.8 ED UMC CS: a portrait prime for mirrorless cameras

Samyang MF 85mm F1.8 ED UMC CS

Samyang is launching a new portrait prime which is designed to work on a wide range of non-full-frame mirrorless cameras. The Samyang MF 85mm F1.8 ED UMC CS will be available in the following four mounts from September:
• Fujifilm X
• Canon M
• Micro Four Thirds (MFT, for Olympus, Blackmagic and Panasonic cameras)
• Sony E-mount (APS-C cameras)

The lens will also be available as the Rokinon Digital Photo 85mm F1.8 Compact Prime in North America.

 The short telephoto focal length and wide maximum aperture of f/1.8 make this the perfect choice for portrait, wedding and portrait photographers. The lens does not feature autofocus or image stabilisation, and is designed to be focussed manually by the photographer.

The lens weighs just over 340g and measures 80mm long (without the supplied lens caps or lens hood). It is constructed with 9 lens elements in 7 groups. A high-refractive and an extra-low dispersion element, along with Ultra Multi-Coating (UMC) are said to  help minimise chromatic aberrations and deliver clear, vibrant images. "This lens is ideal for portraits, with beautiful bokeh from its floating-element system", says the press release.
