Sony SEL20TC 2x FE Teleconverter

The Sony SEL20TC is a 2x teleconverter for Sony FE telephoto and macro lenses. It mounts between the lens and camera and doubles the focal length: a 70-200mm becomes a 140-400mm, and a 200-600mm reaches 1200mm. That’s useful for wildlife, sports and any time you can’t get closer to your subject. Autofocus, exposure metering and the lens’s Optical SteadyShot keep working.

Good to know before you book

• You lose 2 stops of light: an f/2.8 lens works like f/5.6, an f/4 lens like f/8. In dim light you need a higher ISO or more light.
• Because the converter’s front element protrudes into the lens, it only fits the lenses listed below.
• With the Sony FE 100mm f/2.8 Macro GM OSS, the SEL20TC raises the maximum magnification from 1.4x to 2.8x and gives you more working distance, which helps with insects and other live subjects.
