Thanks again for all of the responses!


Fast lenses are great and I always wanted a 400mm f/2.8, but I never envisioned that the prices would go so high. Thanks Canon, it looks like you'll sell me one lens now instead of two.


I seem to be managing with the 300mm f/2.8 +1.4X (420mm f/4). The 400mm f/2.8 would represent faster AF and shooting night games at ISO 6400 at f/4 vs. ISO 3200 at f/2.8. However, I probably only shot about 5 night games last year. With some extra editing time, the noise could be removed.


Another question to ask, is my 420mm f/4 setup too close to the 500mm f/4 with regards to lightweight and versatile travel lens?


I try to think if I needed a super-telephoto lens for the day, or on vacation and I had a 300, 400, 500, and 600 in my closet which one would I want to grab. For some reason I'm drawn to the 500mm II for it's size, hand-holdability and versatility. I wouldn't need the 1.4X for surfing with the bare naked 500mm, which will help with AF.


See, if I buy the 400mm II, I have a feeling that I may still want the smaller 500mm II and that would be crazy to own both of them. But if I keep my 300mm and add a 500mm then that doesn't sound too crazy to me.


What would give a better bokeh and athlete/subject isolation, 400mm f/2.8 or 500mm f/4? I'm thinking 500mm f/4.


Will Canon come out with a user adjustable FF/Cropped 1D body?


Enquiring minds want to know!


OK, so the cats out of the bag and now you all know that I'm nuts!
