$300 Sony Sal-20tc 2x Af Teleconverter

Brand new, unused. Comes with leather Sony pouch. Normally retails for $499-$549.

The Sony SAL-20TC AF 2x (D) Teleconverter will increase the focal length of a lens by 2x, and reduces the lens aperture by approx. 2 f/stop. It was specifically designed to provide full AF compatibility with a select range of Sony (or equivalent Minolta) pro-level G-series lenses (with Minolta, only with Maxxum 7/5/4/3 or newer cameras). For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6.

Note: Due to the high-quality design of this converter (6 elements/5 groups), the teleconverter will only fit and work with a select range of lenses, and only the following Sony lenses are compatible:

70-200mm f/2.8
300mm f/2.8
135mm f/2.8 STF (manual focus)

Only the following Minolta lenses are compatible:

300mm f/2.8 (D) SSM
