I do lots of sports shooting (currently with a D80) and am looking for another body, something that has higher frames per second and a more rugged construction that the D80. Was looking at the D300 but then stumbled across the D2X and fell in love with the high speed 8 fps in 7 MP mode and the 2.0 field of view option for sports and you can still have 12 MP when you want. I know the D2X is heavy but not worried about that, the only apprehension I may have would be the ISO range. This would be used for night sports and a SB-800 could be used along with an 80-200 f/2.8 so the ISO wouldn't have to be excessively high, but it would need to be up there. How bad is the noise on this at high ISO? Oh, and in addition, I have been able to handle both and liked the feel of both so it's not a matter of comfort. D2X currently about $1100 used on KEH wheras the D300 about $1600 new. Thanks, Gabe.
