Excerpt: I just got the 2x III and attached it to my EF 600mm f/4L lens to do some test shots from my home. The lens, with the 2x, is extremely sharp and easy to focus. Also, finding the subject was also fairly easy, for a long lens with a 2x.
Excerpt: Got this item a couple weeks ago. Works fine with my Canon 300mm f2.8L and the new 100-400 f4.5L IS III. Focus is a bit slow at times, but using this for stills and moon photography it's not really an issue.
Pros: Consistent Output, Durable, Easily Interchangeable, Strong Construction
Excerpt: I am very pleased with the Canon Extender EF 2X III. I use it for extending the range of my Canon f/2.8 70 - 200mm L II USM lens with excellent results. It is very sharp, and gives me an effective 140 - 400mm lens for reaching out to capture images of shore birds.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Rugged, Strong Construction
