My D50 is getting a bit long in the tooth, and I think it's time to start looking for some sort of replacement, probably second-hand, in DX format (no point looking at FX since I can't afford to swap all my lenses). I'm in no rush for this, I'm just wondering what people thought was a logical next step.
I don't need hugely high pixel count - even 8MP is probably enough for my needs, though more would be better.
I do need support for the old style autofocus if at all possible - my best zoom is AF, not AF-S. And I sell old lenses and need this for testing them (though at a pinch I could keep the D50 body for that).
I'd like live preview but can live without it
I'd like a self-cleaning sensor if possible.
Any suggestions?
