I just got this lens a week ago...it is awsome, much sharper then the 80-400. I guess that's the difference in the speed. Now I really lust for the 300 2.8. I will post some pictures as I get them edited.
LOL!Welcome to the club. Literally, you could club a baby seal with this lens.
You have just begun a fun experience that gets better as you get to "know" the 70-200. My copy still has the ability to make me say "wow" on a regular basis, even after over 3 years and thousands of images. I'm always excited to open up a card of 70-200 images because it's better than I am and has a tendency to produce great images.I just got this lens a week ago...
