Product Research


Overview: The Sony 1.4x Teleconverter (SEL14TC) increases the focal length of the attached lens by 1.4 times, when mounted between the camera and the lens. The teleconverter is compatible with Sony α series E-mount cameras, and is recommended for full-frame cameras. It cannot be used on Sony A-mount cameras, or with any mount adapters.

Construction: The 1.4x teleconverter features 6 lens elements in 5 groups, including one aspherical lens element.

Teleconverter Attributes: The teleconverter multiplies the focal length of the lens used without degrading its optical performance, auto-focus speed and precision, or operability. It allows you to extend the focal length so you don't have to carry additional large, heavy lenses. Attaching the teleconverter changes the f-stop, maximum magnification, and depth-of-field specifications of the lens:

  • F-stop: 1 f-stop higher (slower) than the attached lens
  • Maximum Magnification: 1.4x the attached lens
  • Depth of Field: approximately 1/1.4 of the attached lens


  • Dimensions: Diameter - 2.456", Length - 1.315" (1.629" w/lens caps)
  • Weight: 5.9 ounces
