Sony FE 50mm F1.8 (SEL50F18F) - Interchangeable Lens Manual and Review


This instruction manual explains how to use lenses. Precautions common to all lenses such as notes on use are found in the separate "Precautions before using". Be sure to read both documents before using your lens.

This lens is designed for Sony α camera system E-mount cameras. You cannot use it on A-mount cameras.

The FE 50mm F1.8 is compatible with the range of a 35mm format image sensor.

A camera equipped with a 35mm format image sensor can be set to shoot at APS-C size.

For details on how to set your camera, refer to its instruction manual.

For further information on compatibility, visit the web site of Sony in your area, or consult your dealer of Sony or local authorized service facility of Sony.

Notes on Use

  • When carrying a camera with the lens attached, always firmly hold both the camera and the lens.

Precautions on using a flash

  • When using a flash, always remove the lens hood and shoot at least 1 m (3.3 feet) away from your subject. With certain combinations of lens and flash, the lens may partially block the light of the flash, resulting in a shadow at the bottom of the picture.


  • When using the lens, the corners of the screen become darker than the center. To reduce this phenomena (called vignetting), close the aperture by 1 to 2 stops.

Identifying the Parts


  1. Lens hood index
  2. Focusing ring
  3. Lens contacts*
  4. Mounting index

* Do not touch the lens contacts.

Attaching and Detaching the Lens

To attach the lens
(See illustration .)
Attaching the Lens

  1. Remove the rear and front lens caps and the camera body cap.
  • You can attach/detach the front lens cap in two ways, (1) and (2). When you attach/detach the lens cap with the lens hood attached, use method (2).
  1. Align the white index on the lens barrel with the white index on the camera (mounting index), then insert the lens into the camera mount and rotate it clockwise until it locks.
  • Do not press the lens release button on the camera when mounting the lens.
  • Do not mount the lens at an angle.

To remove the lens
(See illustration.)
Detaching the Lens

While holding down the lens release button on the camera, rotate the lens counterclockwise until it stops, then detach the lens.

Attaching the Lens Hood

Attaching the Lens Hood

It is recommended that you use a lens hood to reduce flare and ensure maximum image quality. Align the red line on the lens hood with the red dot on the lens (lens hood index), then insert the lens hood into the lens mount and rotate it clockwise until it clicks into place and the red dot on the lens hood is aligned with the red dot on the lens.

  • When using a built-in camera flash or an external flash attached to the camera, remove the lens hood to avoid blocking the flash light.
  • When storing, fit the lens hood onto the lens backwards.



There are three ways to focus.

  • Auto focus
    The camera focuses automatically.
    • Operating sounds may also be recorded during movie recording.
  • DMF (Direct manual focus)
    After the camera focuses in auto focus, you can make a fine adjustment manually.
  • Manual focus
    You focus manually.

For details on mode settings, refer to the instruction manual supplied with the camera.
