## Long description

The Yongnuo YN-50MM F1.8S DA DSM II is a fixed-focus 50mm prime lens designed for MILC cameras with a Nikon-compatible mount. It features an optical construction of 8 elements in 7 groups, a maximum aperture of f/1.8 and a maximum magnification of 0.15x. The lens has a 50 mm filter thread, a 6.4 cm diameter and a 58 mm length, and supports both autofocus and manual focus modes. Weighing approximately 134 g, it is a compact option for portrait, street and low-light photography on compatible mirrorless bodies when used with the appropriate Nikon-adapted mount.
Advantages
The large f/1.8 maximum aperture provides shallow depth of field control and improved performance in low-light conditions while maintaining a compact form factor. The optical design of 8 elements in 7 groups balances rendering and aberration control for a standard 50mm field of view on compatible bodies. Low weight and small dimensions make the lens easy to carry and handle during extended use. The lens supports both autofocus and manual focus operation, giving flexibility for different shooting situations.
Suitable for
Portrait photography with natural perspective and subject separation
Street and documentary photography requiring a discreet, lightweight setup
Low-light situations where a wide maximum aperture helps maintain usable shutter speeds
Everyday general-purpose shooting on compatible mirrorless cameras with Nikon-adapted mount

How to use
Mount the lens on a compatible MILC body using the Nikon-compatible bayonet. Use autofocus for general shooting and switch to manual focus for precise control or creative focus effects. With the wide f/1.8 aperture, select appropriate exposure settings (ISO, shutter speed) to avoid overexposure in bright conditions; stop down the aperture as needed toward the listed maximum aperture number for increased depth of field. Use the 50 mm focal length for natural perspective in portraits and everyday scenes, and maintain a minimum subject distance of about 0.45 m when framing close subjects.
Usage recommendations
For best results, combine the lens with a camera body that supports the Nikon-compatible mount and use a steady hand or support when shooting at low shutter speeds. Use complementary 50 mm filters for protection and creative control. Switch to manual focus when precise focus or focus stacking is required.
