My situation may be slightly diiferent,as i'm planning on getting a 6mp body as well as keeping a 2.74mp body, not backing up with same size. Pretty much for what Tom has said.I would like to put the longer zoom on a 6mp body and put the short zoom on the 2.74mp body for those quick portrait shots which are herd to do at some horse show facilities with a long zoom,plus the scale factor. Wither i purchase a *kist and utilize 10-14 K,M42 and Kaf lenses or stick with Nikon were i have faster glass,and more money put into,remains a huge hummm for me still. :-) The D2h is still a mistery,as i keep hearing to many different reports on it,but still sounds good for my work,or the *kist which mande me think about with new firmware already. Prices on D1H's and D1X's are falling and may fall far enough that i purchase one of those for the main camera and use the D1 as the "spare"
