Selling an absolutely mint Canon EF Extender II 1.4x Teleconverter. In case you're unfamiliar with it, it will multiply the focal length of the lens it's mounted on by 1.4x (for example, a 200mm lens turns into a 320mm lens). It's weathersealed and built to the same high standards as the L lenses. It is compatible with Canon L lenses that have a longer than 50mm focal length (100mm macro, 135L, 70-200mm, 300mm, 400mm, etc). The lens will come with front and rear caps and a generic soft pouch. I'm also selling a Canon 70-200mm f2.8L IS II USM that works beautifully with this extender. If you see this ad, it is still available, so please don't ask...otherwise, feel free to message me if you have any questions!
