Product Overview
Main Features
  • Converter
  • Canon EF
This extender has been re-designed optically and offers excellent performance with compatible EF lenses (same as the Extender EF 1.4x II). It features a new seven-element design, and same weather-resistant design and anti-reflection internal construction as the new EF 1.4x II. The EF 2x II doubles the focal length of any lens it's mounted to, and reduces its effective aperture by two stops. With the EF 2x II, AF is possible with any EOS body if the lens has an f/2.8 or faster maximum aperture, and compatible Image Stabilization lenses maintain the IS feature when used with any current EOS camera.

Product Reviews
Rated 4.8 out of 5 by 5reviewers.
Rated 5 out of 5 by Fantastic I was in Italy to see the formula 1 gran prix and I use this with the 70-200. The result is more than perfect and I print some on a big format with my canon printer October 1, 2016
Rated 4 out of 5 by Great extender. No AF on lenses slower than 2.8 This is a must for any photo kit, BUT you have to remember, the AF does not work with lenses slower than f/2.8 ! ! ! November 13, 2009
Rated 5 out of 5 by New and improved? Yes! Unlike the EF 1.4X II the EF 2X II shows noticable improvement in image quality and in particular contrast over the old Ef 2X extenders. I have used it with various EF 70-200 2.8L IS USM, EF 300 4L IS USM, EF 300 2.8L USM, EF 300 2.8L IS USM, EF 400 2.8L IS USM lenses mounted on EOS 1D, EOS 1Ds and EOS 1Ds mkII bodies. The difference is subtle but noticable and IMO worth the upgrade cost given the less than perfect optical performance of the original EF 2X extenders. I can say that if you are needing to gain this much more focal length you are much better off using a longer lens. But if you are at the limit of your bag or kit this one little extender can sometimes put meat on the table with careful use. August 7, 2009
Rated 5 out of 5 by A must in every photo bag I have had the 1.4x and the 2x extenders for a while now and they are a must for every photo kit. They both are an excellent addition to the 70-200 f/2.8L IS. Autofocus is great on both my MkIIn and the 40D. They are great for plane-spotting and the zoo. They also do a great job with sports.

Rated 5 out of 5 by Excellent extender! I use this extender with the 70-200 IS lens for a long time and it is better than i thought! It's very sharp from corner to corner and the autofocus does not slow in comparison with the 70-200 IS alone. Excellent form every aspect!!! November 15, 2008
