Samyang has expanded its Prima series of compact autofocus lenses with the introduction of two new models: the AF 16mm f/2.8 P FE and the AF 85mm f/1.8 P FE. These new additions follow the release of the AF 35mm f/1.4 P FE, which was the first lens introduced in the Prima series: all three lenses are designed exclusively for Sony E-mount full-frame cameras and are also compatible with APS-C models, where they offer adjusted focal length equivalents.

Both lenses feature a minimalistic barrel design that includes an autofocus/manual focus switch, weather sealing rated at IP5 for dust resistance and a USB-C port located in the lens mount for firmware updates. They are also constructed from Samyang’s proprietary engineering plastic. A red ring around the mount is a consistent aesthetic feature across the series.

The AF 16mm f/2.8 P FE is an ultra-wide-angle prime lens weighing 207 grams and measuring 70.5mm in length. It offers a minimum focusing distance of 12 cm and a maximum magnification ratio of 1:3 on full-frame. When used on an APS-C body, the effective focal length becomes 24mm, and magnification increases to 1:2. Optically, the lens includes eight elements arranged in seven groups, featuring one high-refractive index optic, three extra-low dispersion elements and one aspherical element. The aperture ranges from f/2.8 to f/22 via a seven-bladed diaphragm. Autofocus is driven by a linear STM motor.

The AF 85mm f/1.8 P FE, weighing 272 grams and measuring 71.5mm, is positioned as a lightweight portrait prime. Its optical formula consists of nine elements in eight groups, including one high-refractive index optic and three extra-low dispersion lenses. The aperture ranges from f/1.8 to f/22 using a nine-blade iris, and the lens has a minimum focusing distance of 0.8 meters and a reproduction ratio of 0.12x. According to the manufacturer, it is optimized for smooth background separation and shallow depth of field, aided by the fast maximum aperture.
