About the Sony SEL14TC 1.4X Teleconverter

Extend your reach by 1.4X

If you shoot sports or wildlife, sometimes a little extra reach makes all the difference in getting the winning shot. Sony's SEL14TC 1.4X teleconverter is a lightweight, compact alternative to lugging around a bulky extra lens. Attached between your Sony E-mount camera body and a compatible lens, it increases the lens's effective focal length by 40% without degrading image resolution. This converter is currently only compatible with Sony's SEL70200GM 70-200mm zoom lens, and will increase its zoom range to 98-280mm on full-frame Sony E-mount cameras. On APS-C sensor E-mount cameras the equivalent focal length is 147-420mm.

Sony SEL14TC 1.4X Teleconverter Review

Jason from Los Angeles, CA on 7/31/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was searching for a device that could give me a little more zoom to my Sony FE100-400mm and came across the Sony SEL14TC 1.4X Teleconverter. I couldn't be happier with the results I got! I did do some reach and the consensus was that the 1.4x Teleconverter is better than the 2.0x Teleconverter. I'm not a professional photographer but rather a dad trying to take great pictures of my kids! My combination of this Sony SEL14TC 1.4X Teleconverter and my Sony FE 100-400mm lens allows me to capture spectacular photos of my children catching waves in the ocean all from the comfort of my folding chair on the beach! If my short review does not convince you that this Teleconverter is a wonderful compliment to your setup, then contact Crutchfield and they will be able to answer all of your questions as they did for me. Forever a Crutchfield customer!

Pros: Small Build quality Increase in zoom

Cons: Price

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. It is currently only compatible with the Sony SEL70200GM lens. The 1.4x Teleconverter comes with front and rear lens caps and a zippered storage case.

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
