Designed for portraiture, landscapes, and astrophotography, the AF 135mm f/1.8 FE from Rokinon is a medium-length telephoto prime designed for full-frame Sony E-mount mirrorless cameras. Offering outstanding resolution, the optical design incorporates three extra-low dispersion elements and an ultra-precision aspherical element, which suppresses both chromatic and spherical aberrations for improved sharpness, color accuracy, and clarity. An ultra multicoating has also been applied to reduce ghosting and flare in order to achieve higher contrast when working in strong lighting conditions.
The lens has a linear STM autofocus motor for quick, quiet, and precise focusing performance, plus a minimum focusing distance of just 27.2" to suit working with close-up subjects. Three different customized buttons for enhanced functionality include a focus hold button, a custom switch, and a focus range limiter switch. It also has an astro-focus function for astrophotography. The weather-sealed construction offers protection against dust, light rain, and snow.

Rokinon 135mm f/1.8 AF Overview
Medium-length telephoto prime designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it provides a 202.5mm equivalent focal length.
Bright f/1.8 maximum aperture benefits working in low-light conditions and also affords significant control over depth of field for working with selective focus techniques.
Three extra-low dispersion elements reduce color fringing and chromatic aberrations in order to produce greater clarity and color rendering.
Ultra-precision aspherical element provides natural and refined bokeh.
Ultra multicoating reduces flare and ghosting for increased contrast and a neutral color balance.
Linear STM autofocus motor works in conjunction with Sony cameras' focusing systems for quick, quiet, and precise AF control.
Custom switch can be used for lens-based control over select exposure or shooting functions, such as aperture selection, with additional settings coming via future firmware updates.
Focus hold button lets you keep the lens locked to your desired focusing distance. Also allows you to assign functions such as Eye AF in settings on the camera body.
Focus limiter switch lets you constrain the focusing to two different ranges to suit different applications: 27 to 79" for closeup shooting or 59" to infinity for standard shooting.
Astro-focus mode for astrophotography.
Eleven-blade diaphragm contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
Weather-sealed construction helps protect against dust and moisture.
Included lens hood helps to block stray light from causing flare and ghosting.

Rokinon 135mm f/1.8 AF Reviews
Lighter, cheaper, great images, no regrets
By James
Rated 5 out of 5

Love this lens for the compression and bokeh/shallow depth of field it provides, ESPECIALLY considering how lightweight it is and how much less expensive it is compared to other brands' offerings. It's easy to carry around and doesn't feel unwieldy on my a7Cii; couldn't say that about the equivalent GM offering that I tried before picking this up. Autofocus is solid and reliable for portraits and even some moderate action such as pets and kids, and the rendering is beautiful. I've had this lens for several years now and can comfortably say that if you're interested in a 135mm prime and don't truly need the first party autofocus speed or frame rate advantages, you won't regret picking this up!
Better than I expected
