He may have a glowing review but I will take his advice from the book
The Art of Bird Photography The Complete Guide to Professional Field Techniques - Arthur Morris copyright 1998,2003 Chapter 1 Choosing the right equipment pg 21
"Choosing and purchasing a camera system and a telephoto lens today is a daunting and expensive proposition.....Surely you will want to research and test various brands before purchasing a telephoto lens.
Read but also be wary of,the products reviews in various photography magazines. (My favorite lens the Canon EF 400mm F5.6L, was trashed in a review by one of the top photography magazines.) On the otherhand , be wary of glowing reports."
Yes maybe the 600II + 1.4X is the new darling over the 800, but like any fad, times change, new gear is released. At one time his fav was the old 800L FD, from the book it became the 400 5.6, eventually the 800L now it appears it is the 600 II+ 1.4X. That may change again if the rumored 800 II is true or if Nikon's rumored 800 is a hit.
At the end of the day flagships will change as new ships are built. This is great for those who don't mind 2nd hand gear as there will always be the rush to get the latest flagships which will benefit those in the 2nd hand market.
Now Peter why didn't you tell me this before
"A new top-of-the-line bird photography setup, e.g. 800L + 1DX, will set you back by close to $20,000."
If I knew all I needed was a 1DX............Here I thought all along it was all about the MP war.
