#5. "RE: Is the D700 the optimum upgrade path from D70?" In response to In response to 0
I think the biggest problem in going from a DX to FX is lens related. I would have to basically replace my 12-24mm and 18-70 with around $3,800 worth of lenses, (14-24mm and 24-70mm), so in fact, I'd be spending more like $6,800 for a D700 vs. around $1,700 for a D300.
I hate to say it, but FX is not viable for me, right now. I especially say that, as in tests that have been performed on FF sensors, they are very lens demanding cameras, which means cheap, FF lenses are a non-starter.
