In this case, I am renting the 400 to take it up to Magee Marsh on Lake Erie. I just put in another rental request with the camera store this afternoon for a sturdy tripod and a gimbal head. When I am ready to buy a big lens (not now), I will probably go with the 500mm f4L IS.
My thinking for choosing the 400 f2.8 to rent now is to be able to use my 2X TC with AF, and to get 800mm focal length. I plan on using my 40D with it to get more reach in good light, and my 5D MK II when the light is low. I will see how this set up works at the end of the month!
As for the Sidekick, I would like to have this for birding, but it will not work with my Bogen ballhead. I will have to think about this some more. It will require the purchase of an Arca-Swiss type head as well. :eek:
When I come to Colorado on July 3, I will have my 300mm f4L IS and 1.4X, which I usually handhold.
