Er, Bob... should I take that as an insult or what? ;-)
Just couple of weeks ago I was outside shooting for about an hour with my
EOS 3. The temperature was -22 celcius then. I did loose my battery power
then. But that was because of the cold, and definitely not because the
battery had shrunken in any ways! (This is a strange thought brought up by
a pro at the second link at the top.) Yes, the battery lost it's power
(you could hear the film drive get slower just before) and later on as it
got warm again, it got it back. But shortly after it died completely, so I
checked my notes and it was actually quite old battery after all.
I've also done shoots like that with both the EOS 50e and EOS 3 earlier
on. I.e. I've used them both in sub -20 degrees temperatures. No problems
ever. (Although I did usually use EOS 50e with the battery pack and
NiCd's.)

I've used EOS 5 and EOS 1 and compared those to my EOS 50e at that time. I
didn't then notice any differences. Now that I have the EOS 3, I have
definitely noticed a difference between EOS 3 and EOS 50e. EOS 3 has
always been superior. So I do not believe that the EOS 50e would be as
good in terms of AF (specially when shooting flying birds) as the EOS 3 is
when using the 100-400 IS. (I've of course tried this, but my experiece
from shooting flying birds is quite limited...)
But what comes to the shooting technique... how should you shoot those
birds? Anybody doing it more with EOS 3 or EOS 1V? I mean, should you just
use the central point (limiting AF to one point gives more computing power
to the AF system)? Use it with either CF17-1? Or CF17-2? Or maybe use all
the points (starting the focus tracking with middle point)? There are
quite a few possibilities here... which one is the best? Or does it depend
on the subject; i.e. if the bird is large, use just the middle point? and
if it's small and moves erratically then you have to use all the 45 points
to keep it in focus?
But one thing I've notices though... it the background is almost at the
same distance and quite busy, the 45 point AF can at times suddenly jump
the the background and therefore you will miss the shot. That's why I've
not really tried the full 45 points AF tracking that much... even though I
have the feeling that in some situations it's the system one should use.
Best regards,
Hugo.
