I am going to canada in a month for a fishing trip and thought it would be fun to take my gear with me. I am going to bring my 18 - 55 IS and thought I would rent a 100 - 400...or a 70 - 200 F4 IS.
But, never using the 100 - 400, will I be able to cope/adjust to the push/pull zoom? is the 70 - 200 F4 IS such a great piece of glass that I won't miss the xtra 200 mm? Sure, I MIGHT miss a shot, but I understand that the 100 - 400 is a lot bulkier.
Knowing I will be in a boat most of the time I will be using either of these lenses, which would be the better lens? This will be for shooting wildlife and I should have pretty good light.
Thanks for your thoughts!

Jess
