I know, only I can answer that question. I've had a hard time making the transition from film to digital, and it's not IQ, but the change in perspective that stymies me. My current dSLR is D80/16-85 zoom. Left over from my film days are just about all the 2.8 AI/AIS primes from 24 mm to 200 mm plus two good zooms - 28-105 and 75-150. These are all much faster than the 16-85 I'm currently using, and all come back to life on the FX700.
Yes, $3,000, is a lot of money, but there are no additional lenses to purchase. It actually becomes more economical than adding new fast lenses to the D80 or a D300.
My only hangup (besides price) is the size. I do a lot of backpack/nature/trekkinng/travel type stuff where small size and not being conspicuous are important.
All things considered, this seems to be the first dSLR I'm actually excited about purchasing.
