Have used third party extenders and they were good but this one is awesome! I'm using it on a 70-200 f4 IS USM attached to a 7D Mark II and it works flawlessly. Auto focus is quick and I can hand hold it with no problem and I am an elderly gentleman. Highly recommend.

This is a superb extender which works flawlessly with the Canon prime telephoto and super telephoto lenses. I bought it to supplement my Canon 300 mm f/2.8 IS II lens to give me an effective 600 mm f/5.6.

    Very cost effective way of increasing your telephoto reach. It's very light and compact.

    Loss of two stops of light compared with the mated lens.

This is the second Canon 2x extender I've had. I use this with a full frame Canon 5D Mark III and find it remarkable for getting closeups of people in day-to-day activities, sports, and closeups of flowers and of wildlife (e.g., elk and bison in Yellowstone National Park).

Outstanding images with this in conjunction with my 300mmF2.8L. Frustrating that it does not work with the 100-400 F4.5L ll USM, while it did work with the original version of this lens, (although this was not consistent). I also own the 1.4x extender.

Tested this like 5 weeks ago. The Extender 2x III performs better on my 70-200L IS Mk2 than on the Mk1. There is a noticable difference in AF and IQ. I had them side by side. The Extender 2x III gave no improvement on the 70-200L IS Mk1 over the Extender 2x II. I got the Extender 2x III in the end.

    Good build, good image quality, still fast AF
