Samyang AF 35-150mm F2-2.8 Sony FE

Samyang AF 35-150mm F2-2.8 Sony FE – versatile 35–150mm zoom with bright F2–F2.8 aperture

The Samyang AF 35-150mm F2-2.8 for Sony FE is a single zoom that covers a wide range of popular focal lengths while maintaining a bright maximum aperture. It suits both stills photographers and videographers who need flexibility across portrait, travel, street and landscape shooting scenarios. The lens combines a broad zoom range with fast apertures and video-oriented features to support varied workflows.

Aperture and focal range

The lens offers a maximum aperture of F2 at the wide end and F2.8 at the telephoto end. This bright aperture range helps separate subjects from backgrounds and supports low-light shooting. In addition, the zoom range covers five commonly used focal lengths: 35, 50, 85, 135 and 150mm, allowing you to work across many shooting situations without changing lenses.

Optical construction and coatings

The optical design consists of 21 elements in 18 groups. Samyang combines multiple special elements—2 ASP, 1 HB, 3 HR and 6 ED—to maintain strong optical performance across the zoom range. UMC (Ultra Multi-Coating) is applied to reduce flare and ghosting, which helps produce clearer, more natural images under challenging light conditions.

Bokeh, diaphragm and close-focus

The lens uses a 9-blade diaphragm to produce smooth, attractive bokeh. Combined with the fast aperture, this diaphragm helps create subject separation and pleasing out-of-focus backgrounds. The minimum object distance (MOD) is only 0.33m, which lets you get close to subjects for unique perspectives and pronounced background blur, making it useful for near-macro style close-ups.

Autofocus and video-friendly design

Samyang equips the lens with a Linear Stepping Motor (STM) for autofocus. The STM delivers fast, responsive AF performance suitable for both photographers and videographers. For video work, the AF speed is calibrated to mimic the more gradual focus changes of cinema lenses, offering smoother transitions while recording. The lens also features a digital parfocal design specialized for video: when you focus in manual focus (MF) mode, the focus remains accurate even after zooming in or out, reducing the need to refocus during a take and saving shooting time.

Manual focus behavior and focus breathing

When you switch to Linear MF, the lens adjusts focus control to match the torque of the focus ring as closely as possible to that of a manual lens, providing a more natural manual focusing feel. Samyang has also worked to keep focus breathing to a bare minimum, which helps maintain consistent framing and composition during focus pulls in video production.

Build quality and controls

The lens is fully weather sealed with sealing applied in 11 areas to protect against dust, light rain and snow. This level of protection helps you shoot in variable weather conditions without immediate concern for contamination or light moisture.

On the lens body, you will find custom switches and buttons that allow you to control various functions directly. The lens offers three custom switches that can be assigned to preferred operations such as focus save, dolly shot or aperture ring behavior. Additionally, Samyang provides future expandability: more functions can be added via firmware updates when connected to the Samyang Lens Station.

FAQ

question: Is this lens suitable for both photography and video?
Answer: Yes. The lens is designed for stills and video, offering a bright aperture range, smooth bokeh and video-oriented features such as a digital parfocal design and AF tuning for cinema-like focus transitions.

question: How close can I get to a subject with this lens?
Answer: The minimum object distance is 0.33 m, which allows close working distances and strong subject isolation when combined with the lens's wide apertures—useful for near-macro perspectives and creative close-ups.

question: Is the lens protected against weather elements?
Answer: Yes. The lens has weather sealing applied in 11 areas to help protect against dust, light rain and snow, enabling more reliable use in varied outdoor conditions.

question: Can I customize the lens functions or get updates?
Answer: Yes. The lens features three custom switches for on-lens control, and additional functions can be added via firmware updates using the Samyang Lens Station.

question: How does the autofocus perform for video and focus pulls?
Answer: The Linear Stepping Motor (STM) provides fast and responsive AF for stills, and for video the AF speed is adjusted to mimic cinema lens behavior. The digital parfocal design and minimized focus breathing also help maintain consistent framing and smoother focus transitions for filmmaking.
