Summary: The extender does not auto focus on either of my cameras and there was no mention of that on the information when purchasing. I purchased the new one to work with the new 100-400 lens but have since learned that it doesn't auto focus on the moving setting on the Canon 5D11, 7D or the 5D111 or 7D11...
Given a fair evaluation, the EF 2XIII Extender simply did not make it.

Summary: Failed Basic Quality Comparison. In wildlife photography, one seldom sees a distant object filling the the frame. Therefore, options often include: 1. cropping to the desired object size, or 2. using a longer lens, or 3. using an extender with a long lens.
Cropping in Lightroom 5 so far is VASTLY superior to this

Summary: So far I am not impressed. Just got this to use with a Canon 70D with a 70-200mm f2.8L and a 400mm f5.6L. works mechanically with the 2.8L "focuses" fast. 400mm f5.6L - will NOT focus in AF mode unless you tape the pins..
Summary: I am so very disappointed in this product, I am sending it back. I've used it for less than a week, am a professional photographer, and have used this in a) good outdoor natural light b) with a weighted tripod and c) with a still subject and every single image is soft. Sharpness is gone.
Excerpt: I have now tried two of these Teleconverters with the same results. They both caused softening of the image or reduced quality. I bought my 500MM II with hopes of being able to use this product but sadly disappointed. I tested both under many controlled tests and all results were the same.
