Simonkenton7:
What are you using, a 400 mm lens?
Cookie runs around with three cameras, all Canon gear, and near enough to put one in cosigner land. Makes the gun safe seem inexpensive.
1= EOS 70D oldest and a 1.6 crop sensor wearing an 18 to 55 mm lens for the typical landscape/camp shots.
2= EOS 5D that I think is 1.4 crop sensor wearing a 100-400 mm lens. With the crop sensor its the equivalent of a 140 to 560 mm
3= EOS 7D which I believe is full frame and its wearing a Canon 500mm prime.
The 100-400 is her mainstay, and the 500 big gun is for reaching out.
Simon, I asked a similar question about a year ago and can add a little more info.
I don't recall the short lens, but if my memory serves, two of Cookie's lenses were the Canon "L series" -- amazing, no compromise optics, fluorite crystal lens elements. (John stops to wipe drool off keyboard).

Base on the images posted here (plus a friend's Canon 500L), it does seem that you get what you pay for -- and 1minute knows that "happy wife, happy life"!
Also, note that these images have been really downsized -- the original images out of the camera must be spectacular, and well-suited to big prints or magazine covers.
