That's good to know, Regis. I personally think that the 100-400 is a great close up lens too. so I agree with you there. but I was happy to see how sharp that lens was using the 2x when everyone on here seems to think it does the opposite

I still have it and use it for close-up photography because it will focus down to 3 feet. So, the Canon 100-400 II
is a keeper because it is a great lens and sometimes the zoom feature comes in handy. But, I can't use the 2x with this lens.
However, the 1.4x works great. So, the 2x used with the DO, gives that extra reach that I need with bird photography.
Thank you very much, foathog.
