Key Features:

  1. Aperture:
    • Maximum Aperture: F1.4
    • Minimum Aperture: F22
    • The large F1.4 aperture is ideal for low-light photography and achieving a shallow depth of field, which produces beautiful bokeh.
  2. Optical Design:
    • The lens consists of 9 elements in 7 groups, including one aspherical element to reduce chromatic aberrations and distortion.
    • Multi-coated glass elements help minimize flare and ghosting for higher contrast and color accuracy.
  3. Focus System:
    • The lens features an auto-focus (AF) system, supported by a microcontroller unit (MCU) for fast and accurate focusing.
    • It also has a manual focus (MF) option for more control in precise focusing situations.
  4. Build and Compatibility:
    • The lens body is constructed from high-quality plastic with a metal mount for durability.
    • It is compatible with Canon EF mount cameras, both full-frame and APS-C sensor models.
  5. Additional Features:
    • It includes a 58mm filter thread for attaching various filters.
    • The lens has a minimum focusing distance of 0.45 meters, allowing for relatively close-up shots.


  • Affordability: Compared to similar lenses from major brands, the Yongnuo YN50mm F1.4 offers a competitive price point, making it accessible for budget-conscious photographers.
  • Versatility: The 50mm focal length is highly versatile, suitable for portraits, street photography, and everyday use.
  • Low-Light Performance: The wide F1.4 aperture allows for excellent performance in low-light conditions and offers creative control over depth of field.


  • While the Yongnuo YN50mm F1.4 provides good performance for its price, it may not match the build quality and optical performance of more expensive lenses from Canon or Nikon.
  • Users should be aware of potential issues such as slower autofocus in low-light conditions and occasional chromatic aberrations, which are common in lenses at this price range.
