The YN85mm S DF DSM Lens from Yongnuo is a medium telephoto prime for full-frame Sony E-mount mirrorless cameras. The fast f/1.8 aperture suits working in low-light conditions and enables increased control over depth of field for isolating subject matter.
Upgraded Version with Aluminum Construction & Waterproof Bayonet Ring
This lens is an upgrade from an earlier YN85mm S DF DSM lens. This newer one features aluminum construction, improved lens coating, and a rubber ring around the metal bayonet that prevents water and dust from entering the lens through the rear. The only other difference is a slight redesign in the appearance of the lens. It`s all black, without a red stripe around the top.
AF/MF Switch & Custom Function Button
An AF/MF selector switch allows you to quickly toggle between autofocus and manual focus modes. Next to this selector switch is a customizable function button that can be assigned a shortcut operation or used to pull up a function menu.
Fast f/1.8 Aperture & 7-Blade Iris
The fast f/1.8 aperture allows increased control over depth of field, enabling you to isolate a subject from the background. It allows you to shoot with higher shutter speeds in low-light environments and to achieve a soft blur effect.
Additionally, a 7-blade diaphragm lets you capture smooth bokeh and circular highlights. With the aperture appropriately reduced, the 7-blade diaphragm also allows you to capture photos with star effects.

9 Elements in 8 Groups
The optical design features nine elements in eight groups. One low dispersion element reduces chromatic aberration and color fringing. One high refractive index element reduces spherical aberration and distortion for increased clarity, definition, and sharp image quality.
Multi-Layer Coating
A nano multi-layer coating is applied to each optical surface to suppress flare and ghosting for improved contrast in strong lighting conditions.
Other Features
- Chrome-plated metal lens mount is durable and accurate for a secure fit with the camera body
- Gold-plated contacts for consistent communication between the lens and camera
- USB Type-C firmware update port
- 58mm front filter threads
