D100
D100
The D100's small buffer won't keep up with sports action. If you are exceptionally good at anticipating given moments in a rapidly-unfolding contest, you may grab shots, of course. But you will be disappointed if you expect a D100 to be able to match the sports-winder frame rate of newer dSLRs. The Canon D series is where I would look to kit-up for sports work, although the Nikon D3 is finding favour.
By the way, even with Nikon's best glass, none of my D100 shots ever looked as good as those from my RD-1 bodies. This, in terms of noise, colour fidelity, dynamic range, micro-contrast, et al. Don't expect a D100 capture to please your eye in the way that the RD-1 files do. The output is of a different order. I still have work in my portfolio from D100 NEFS, though, and it holds-up, even though the greater part of my output is now made up of Aptus 65 files. I saw a D100 with grip and two batteries for under 200 UK pounds, the other day. At that price, it would make a great knock-about body for someone who already owns some Nikon lenswear.
Enjoy your photography.
