Sony SEL20TC 2x Teleconverter Lens
Extending the effective focal length of the Sony FE 70-200mm f/2.8 GM OSS lens, the FE 2.0x Teleconverter renders this telephoto zoom as a 140-400mm f/5.6 lens. The dedicated design maintains full communication between the lens and E-mount mirrorless cameras, including auto-exposure metering, autofocus, and Optical SteadyShot image stabilisation. Additionally, this teleconverter also features a dust- and moisture-resistant construction, matching the lens, to benefit working in harsh environmental conditions. 2.0x teleconverter doubles the reach of the 70-200mm lens with only a two-stop loss in exposure. Dedicated design maintains a high degree of image quality as well as full electronic communication to support the use of AE, AF, and OSS. Weather-resistant design matches the construction of the 70-200mm lens itself for use in inclement conditions.

I love this 2X convertor because it DOUBLES the focal length of my Sony 200-600mm zoom lens and the pictures are sharp. The following photo was taken with that combination. Distance from the flower to Sony A6500 camera sensor was between 22-24 feet. Equivalent focal length was 1,800mm.

Essential tool for the professional and highly discriminative enthusiast
Tried with a 70-200 GM lense on A7R3 . lense cant even focus with this teleconvertor on. Manual or auto focus didnt work. Camera does not recognise the lense once this tele is on.
Works like a charm !! love it
It works great. My favorite thing is that it's small. Much smaller than canon
Awesome ! worthy of it.
The sharpest telecoverter I have used. Really saves weight and space when you need the extra reach.
They are among the best teleconverters available but only work on a really limited number of Sony lenses. Most Sony lenses do not physically fit. They are expensive and if your camera has enough pixels you may find post processing gives and equal or better image.
