I know that this really doesn`t belong in this area of the forum, but I posted it here cause you guys will have the expierience, with both the lens and the field I wan`t to use it in.
Well actually there are two lenses.
I am thinking of getting either a 100 - 400 or the 400 5.6 in the future (say a month or two) and would like your opinions on which would be better. The lens would be used almost exclusivly for photographing birds, but I was wondering whether having the versitility of the zoom would come in handy, I know with myself there have been times when I have needed to have less magnification because the birds get to close. But then I also want to use teleconveters with it, primarily 1.4 but also on rarer ocations 2 times, I know that neither of the lens would be fast with the loss of two stops, but i can`t afford the super expensive lenses, so would have to make do. Also allthough I don`t really mind weight, the saying would still be true "the lighter the better."
Ultimatly I am asking primarily for those who have had expierience with both, which one they prefered and why, any other comments by anyone would be grately appreciated.

That said though I am also thinking of purchasing a 24 TSE at the same time, so maybe it would be better to forgo that and get a second hand 500 f4 for a little more, any thoughts?

, good job I got that hide recently!
