Please email us about reserving these extenders.

     These Tele Extenders can be used with fixed focal length lenses 135mm and longer (except the 135mm soft focus lens), and the EF 70-200 f/2.8L, 70-2oo f/2.8L IS, 70-200 f/4L, and the 100-400 f/4.5-5.6L IS zoom lenses. Superb optically, they preserve the image quality of the lens they're mounted to and multiplies it's focal length by 1.4 and 2.0 respectively. Effective aperture is reduced by one stop with the 1.4X, and two stops with the 2.0X; autofocus is possible on any EOS camera when combined with a lens having an f/4 (the 1.4X) or f/2.8 (the 2.0X) or faster maximum apertures. The new II versions maintain the outstanding optics of the previous versions, and add enhanced weather resistant construction, and improved anti-reflective surfaces in the barrel. SHIPPED AS A SET ONLY, these extenders come with caps, all in a fitted Pelican case.
