My wife has always loved her Coolpix 4300, and initially opposed my upgrading to a D70 from my CP5700. HOWEVER, on our recent trip to the Canadian Rockies, she practically took the D70 away from me. She complains about the size and weight, but agrees that it is far more capable than the 4300. Bottom line: we're considering another digital SLR body to share my collection of lenses for our next big trip (New Zealand in January). I'm pretty sure it will be another D70(s) or a D50. I think she will like the smaller size of the D50, but will we be sacrificing much performance compared to the D70? Recommendations anyone? Thanks.
