bigger buffer for RAW images
bigger screen
slightly more mp
better AF
faster write speeds
only things I would like
So you'd like a Nikon?
maybe if I wanted more noise, less mp and less buffer I suppose I could downgrade to a D70s
And don't forget the lack of ISO 100.

Fish:bicycle. I run mine at 400. Wouldn't use 100 if I had it
To a non photographic person with a minimum amount of understanding, why would an ISO 400 rating be better than a 100 (except in poor light conditions maybe ?). I thought the lower the ISO rating, the greater the definition, better the quality. Guess it's not as easy as that. Please enlighten me.

Good Q. It's a trade off between quality and speed. If your work can be done with slow shutter speeds, fine, use a low ISO for least image noise. However with current AF lenses typically starting at f4.5+, you need a higher ISO to get the shutter speeds for 'normal' photography. Well I do, and frankly for the kind of work I do ISO 400 gives me the kind of shutter speed/aperture combinations I need and noise is not a problem. OK, I see noise if I hoof up the brightness in Levels too much on a dark image, but life is a compromise and you have to pick the combo that works best for you.

try taking slow shutter panning shots behind a fence at a track, I often use ISO 50.......
Because YOU don't need low ISOs, don't assume everyone is in the same boat.
