Frequently asked questions
Does the Sony 2X Teleconverter work with the 24-70mm f/2.8 GM?
No, it is not compatible. The Sony 2X extender has a protruding front element that physically prevents it from mounting to standard zoom or prime lenses. It only fits specific Sony telephoto lenses.
How much light do I lose with the Sony 2X extender?
Using the 2X teleconverter results in a 2-stop light loss. For example, an f/2.8 lens will have a maximum effective aperture of f/5.6, and an f/5.6 lens will become f/11.
Does autofocus still work with the 2X extender?
Yes, the SEL20TC maintains full communication between the lens and camera, supporting high-speed Phase Detection AF and Optical SteadyShot, provided the camera body supports AF at the resulting smaller aperture.
