I bought this extender in hopes of liting my load when out in the feild. I shoot a Canon 40D and a XTI as my backup. My thought was attach this baby to the back of my canon EF 70-200mm f/2.8L IS and extend my range and leave the Canon EF100-400L F/4.5 5.6IS at home when not out birding. Auto focus and IS work well on the 2.8 but as you know it does not work for the F/4.5 Well here it is, image quality suffers to much for my taste. For a guy like me this must be used when on a tripod. I dont believe this is the soulution for a serious photographer or even serious amiture. take the 300 bucks and stash it away for a lens with a longer focal legth and buy what you want the first time. Just my two cents!
