The Canon 1.4X TC III is a great option if you need more reach with your compatible telephoto lens. While previous generations had a very noticeable affect on image quality and AF performance, the TC III is huge leap forward. When used with a 70-200mm f/2.8L IS II, image quality and AF remains very high. Throw it on a Canon supertele, and you’d be hard-pressed to notice a difference. However, as a general rule, remember that low light does not mix well with teleconverters. You will see focus hunting.
