1.4 2 or 2 1.4s

Pope says 1.4.  I think man if I only had the 2x then I could get a closer shot on those long distant ones, then what is better, a 2 or 2 1.4's

Most people say that two 1.4x teleconverters gives you the better quality over a 2x.  However, you can't stack 2 Canon 1.4x teleconverters because of the way they are built.  A very good Kenko pro 1.4x and a Canon 1.4x can stack on top of each other.  However, if you have to use more than just one 1.4x teleconverter...you may have choosen the wrong lens.  Only f2.8 prime lenses take a 2x ok.  The quality is greatly diminished.  Whereas a 1.4x barely takes away from a prime lens.  I've used the 2x and would only use it in a pinch if I had to.  I think I would rather use a 1.4x and crop the picture further than use the 2x.  To each his own.  (by the way, you'll lose autofocus with a 40D and a 2x unless it's a f2.8 lens, in which case the autofocus will be really slow)

I think you sold me on th e1.4   If I need 2 then I just need to get closer.  If I am oto just document the animal for you guys, then I can just use the 18 and get a pic of the animal.  For this mission I am going prime with a 1.4.    None available where I was looking.  Apparantly most of the canon glass has been picked up because of hte olympics in china.

Here's one for ya Bone.
Zeiss announced that they have created the world’s largest telephoto lens, a 1700mm f/4 weighing in at 256 kg (564 pounds). It was developed for long-distance wildlife photography. No kidding—you wouldn’t even have to leave your apartment. No word on how much this custom-made lens cost. But if you have to ask…
