Prime lens Yongnuo YN Sony E 35 mm F/2 DF DSM — full-frame/APS-C compatible, F2 aperture

The Yongnuo YN Sony E 35 mm F/2 DF DSM is a 35mm prime lens for Sony E-mount cameras, compatible with both full-frame and APS-C sensor bodies. With a constant maximum aperture of F/2 it provides improved low-light performance and the ability to achieve shallow depth of field effects. The lens is compact and lightweight, designed for general-purpose use such as street, travel and everyday photography while maintaining optical performance appropriate for stills and video.

Advantages

This prime lens offers a bright F/2 aperture that helps when shooting in low light and when isolating subjects with background blur. The DSM (Digital Stepping Motor) autofocus system delivers relatively quiet and responsive focusing suitable for stills and video. The 35mm focal length on full-frame gives a natural perspective for environmental portraits and documentary work, while on APS-C it provides a moderate short-telephoto field of view useful for tighter framing. The lens’ compact form factor makes it convenient to carry and use for extended periods.

How to use

Attach the lens to a Sony E-mount camera body until it locks in place and confirm electronic connections are established. Use the camera’s AF modes and focus settings to engage the DSM autofocus for stills or continuous AF for video. For shallow depth of field, select wider apertures near f/2 and focus on the subject; stop down as needed to increase depth of field. On APS-C bodies, account for the crop factor when composing tighter frames. Handle the lens carefully, keep contacts clean, and use manual focus if precise control is required.

Usage recommendations

For best results in low light and when seeking subject separation, shoot at or near the maximum aperture and use single-point AF for accurate focusing on the subject’s eyes or primary detail. When recording video, enable any in-camera focus smoothing or silence features to complement the DSM motor’s quiet operation. Store the lens with caps on and avoid exposing it to harsh weather without appropriate protection.
