What we like about Yongnuo Yn 50mm F 1 8 II

  • Extremely affordable price point compared to first-party alternatives
  • Improved build quality over Mark I, featuring a durable metal mount
  • Solid center sharpness when stopped down to f/2.5 or further
  • Very lightweight and compact, making it a portable walkaround lens
  • Close minimum focusing distance of 0.35m for near-macro shots
  • Supports firmware updates directly through the camera body

What we don't like about Yongnuo Yn 50mm F 1 8 II

  • Autofocus can be slow, noisy, and prone to hunting in low light
  • Soft image quality and noticeable chromatic aberration when shot wide open at f/1.8
  • No full-time manual focus; forcing the focus ring in AF mode can damage the motor
  • Prone to lens flare and ghosting, especially when shooting toward bright light sources
  • Distortion is higher than expected for a prime lens
  • Inconsistent quality control between different lens copies

Verdict

The Yongnuo YN 50mm f/1.8 II is a compact, full-frame prime lens for Canon EF-mount cameras, featuring an optical design of 6 elements in 5 groups and a 7-blade diaphragm for smooth bokeh. Its notable upgrades over the original include a durable chrome-plated metal mount, a closer minimum focusing distance of 0.35m (1.15ft), and the ability to update firmware directly through compatible camera bodies. Key pros include its high affordability, lightweight 162g build, and a 58mm filter thread that matches common kit lenses. However, users often cite a noisy autofocus motor, lack of weather sealing, and occasional softness at the widest f/1.8 aperture as its primary drawbacks.
