Joel, I'm still not sure if I want a 400mm (sports), 500mm or 600mm. Right now 300mm is my longest bare lens.


Here's a few from today with the bare 300mm.





1D-MKIV: 300mm f/2.8L IS F/6.3 1/1000sec. ISO 400 CPL.














































I would hope to get results like this with a bare 500mm or 600mm, because the 2X is not good enough for BIF or fast action. I do think the 1.4X extender is acceptable for action shots, and the 2X is acceptable for static shots. I'm a little concerned that the 600mm might be too narrow of a field of view for BIF. I would like to try and pick the focal length that I would use most often bare.


C&C Welcome!
