Up for sale is a Canon EF 2x II Extender. I took this lens on a trade and was disappointed to find out that my 1DX II would not autofocus with my 400mm f/5.6 - It will autofocus with my 400 f/4 and a rented 500 f/4 but not with the 400mm f/5.6.  This lens has a pretty deep chip on the front glass- it starts being noticible on my lenses at f/32 and becomes a black spot at f/64. I mainly shoot at f/5.6 to f/11 and have no noticed any issues besides a small lack of contrast in the middle area which can be fixed in Photoshop. Photo samples included at end of product photos.

That being said this lens is being heavily discounted and sold AS IS. Unfortunately this lens will not come with any lens caps.
Will be shipped via USPS Priority Mail.
