Since I always had at least the 1.4X on my 300 2.8, I ended up selling it and getting a 500 4.0, and have to say WOW, I will test it out tomorrow, but love it so far.
I will be using it on both the 1D and 1ds mark III, and also look forward to trying some video with the 5D II.
Congratulation, Denny.
I went the other way, sort of. Bought the 500 a few years ago and bought the 300 f 2.8 about two years ago,
but kept the big guy. Both are great.
Denny Congrats, i too have one on order, i'm a newbie though, so if you have any 411 to share, i'm all ears.
Looks like you have an exciting weekend ahead of you!
