Kenko 2x Teleplus Pro 300 DGX for Canon EF

Description

The Kenko 2x Teleplus Pro 300 DGX is a modern, high quality teleconverter for Canon EF cameras and lenses. Compatible with many (but not all!) EF mount telephoto lenses: compatibility is broader than Canon’s own teleconverters, but not universal. Kenko has some compatibility information here: https://kenkoglobal.com/support/teleplus/. In excellent condition, with original box.
General reminder: most DSLRs will only autofocus lenses with an f5.6 aperture or larger, and bearing in mind that this teleconverter will take away two stops of light, you may want to do the math before buying. For example, using his teleconverter, a 70-300mm f4-5.6 lens will become a roughly 140-600mm f8-11 lens, which will not autofocus at its longest end. In excellent condition.
