Samyang AF 35-150mm F2-2.8 L mount

Samyang AF 35-150mm F2-2.8 L mount – versatile zoom covering 35, 50, 85, 135 and 150mm with bright F2–F2.8 aperture

The Samyang AF 35-150mm F2-2.8 L mount lens provides a flexible focal range and a bright aperture across the zoom. It suits a variety of shooting scenarios, from portraits and travel to street and landscape photography, and it also includes features tailored for filmmakers.

Optical design and image quality

The lens uses a complex optical construction to maintain performance across the zoom range. Specifically, it contains 21 elements arranged in 18 groups, including 2 ASP elements, 1 H-ASP element, 3 HR elements and 6 ED elements. These special elements work together to reduce aberrations and deliver consistent optical quality from wide to telephoto.

In addition, Samyang applies UMC (Ultra Multi-Coating) technology to the lens elements. This coating minimizes flare and ghosting, which helps produce natural and clear images even in challenging light. Furthermore, the lens features a 9-blade diaphragm that contributes to smooth and attractive bokeh when you separate the subject from the background.

Focal range and aperture

The lens covers five widely used focal lengths—35, 50, 85, 135 and 150mm—so you can swap between classic portrait and telephoto perspectives without changing lenses. It offers a maximum aperture of F2 at the widest end and F2.8 at the telephoto end. Consequently, you get a bright lens for low-light conditions and better control over depth of field throughout the zoom range.

Autofocus and video-friendly features

Samyang equips the lens with a Linear Stepping Motor (STM) that delivers fast, responsive autofocus. As a result, it supports excellent focus tracking for both stills and video. When you record video, the AF speed is adjusted to mimic the focus behavior of a cinema lens, providing smoother transitions between focus points.

Moreover, the lens incorporates a digital parfocal design specialized for video. Therefore, after you focus on a subject in manual focus (MF) mode, you generally do not need to refocus when zooming in or out—this saves shooting time and helps maintain stable focus during a take. Samyang has also minimized focus breathing to further support video applications.

Manual focus behavior and control options

When you switch to Linear MF, the lens matches the torque of the focus ring as closely as possible to that of a manual-focus lens. This gives you predictable and tactile control when pulling focus manually. On the lens body, three custom switches and buttons let you assign preferred functions directly. For example, you can map focus save, dolly shot behavior, the aperture ring, and other controls to these switches.

In addition, Samyang offers future expandability: more functions can be added via firmware updates through the Samyang Lens Station, allowing you to customize and update the lens capabilities over time.

Close-up performance

The lens has a short Minimum Object Distance (MOD) of 0.32m. Combined with its fast aperture, this enables unique close-up perspectives with a strongly blurred background. Therefore, the lens is well suited for tight framing and creative near-subject work that benefits from shallow depth of field.

Durability and weather resistance

The lens is completely weather sealed to help prevent damage and contamination from dust, light rain and snow. Consequently, you can use it in more demanding outdoor conditions with greater confidence.
