I'm ignoring the first post.

The AF does not work on a 100-400 when using an extender unless using LiveView.
Other than that, I think it works well.

I am guessing you don't have 1 series Canon body. If you use a taped Canon 1.4X or a Sigma or Tamron 1.4x it will work in bright sunlight. You can get good results with a 1.4x; however I have taken 100's of shots with a Canon 2x and not one is worth saving.

if your local camera store has them in stock, try one out , too many people on this sight have gotten good results to write them off.

I use them both and the combo is good in bright light. The problems is that the largest aperture is f/8 at 560mm so you loose auto focus. That is not a big problem in good light.

hard cold fact...nno matter that once in a while you can get a really great shot.
don't do it...the chance for missing good shots that come out soft on your computer is to great

with respect i have to disagree,i use them on a regular basis and have loads of good pictures, even when i stack 1.5x+2x+2x together.

I have the Canon 100-400 and Canon's 2x extender. With careful manual focusing and a tripod when called for, results are perfect
