Wow Herb that gives you an effective focal length of about 1000mm at f4.5 (ish). What are the results like? I have a Tokina 300mm f2.8 and a 1.7 AF TC (765mm @f4.5) and the results are pretty good. The SMC glass can only make it better...

Mark Cassino and i both use as our birding configuration of choice an A* 400/2.8 with the 1.7X AF extender on an *istD. you can do the math. i have my eye on the FA* 600/4 soley to get publishable birding photos of small wild birds, and i plan to use it with an extender a lot of the time. the A* 1200/8 is a distant possibility too. the only reason Vic didn't see any Canon 1200/5.6 IS lenses is because even for a serious bird photographer, it's out of their price league at $76K street price and weighs 36 lbs. people who have used the Sigma 800/5.6 report that it is good enough to be a viable alternative to manufacturer's glass.
