hello all:


I am driving myself crazier trying to decide which lens to buy. My decisions were between the 70-200f/4 and the 100-400. Canon has now thrown the new70-300L into the mix. I had been told the 100-400 is basically used for objects that don't move, but I have seen some great bird shots, including the hummingbird in flight on the bird photo post on this site. I also have read the review for each lens.


I tried to view the photos from the other posts but for some reason most of the 100-400 photos were not able to be viewed.


I have a 7d that I know will magnify the lens 1.6x. I like the fact the 70-200 is lighter and with the f/4, it will help some withlower light , but the 400 has more reach.


I don't want to sacrifice a crisp photo





Any help will be great
