Canon 1.4X Extender EF III review by cpe1991
Review Date: 12/28/2011 Would you recommend the product? Yes | Total Spent: $500.00| Rating: 10 

Pros: No loss of IQ, no added CA to 70-200mm f/4 IS L
Cons: expensive, not massive increase in focal length

Works beautifully with the 70-200mm f/4 IS, which is a very sharp lens to start with. I use it routinely for bird watching, using it with the 7D as a telescope to give about 5x magnification, and then blowing up on the screen for study in the hide, adding an extra 40% in linear size and 100% in area. A definite increase in resolution on later printing. The combination of extender and 200mm on the 7D is equivalent to a lightweight f/5.6 448mm 4-stop IS lens on a 5D for field of view.
