Useful extender but a bit pricey

AdvantagesDoes what it says on the tin

DisadvantagesA bit pricey and doesn't work with some lenses

This means that autofocus on a 20D, 30D, 40D or 5D body will still function properly at any focal length.

Product Information for "Canon Extender EF 1.4x II - converter" »

Manufacturer's product description

This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS zoom lenses. Superb optically, it preserves the image quality of the lens it's mounted to and multiplies its focal length 1.4x. Effective aperture is reduced by one f-stop; autofocus is possible on any EOS camera when combined with a lens having an f/4 or faster maximum aperture. The version II maintains the outstanding optics of the previous version, and adds enhanced weather- resistant construction, and improved anti-reflective surfaces in the barrel.
