i got rid of my d200 and all the lenses and i am very happy with the choice i made. i started a 365 this year and realised that i had only taken all my kit out once since jan 1st. mainly i used my smallest body (d40) with a 35mm f1.8 or my d200 with an old 28mm prime. a lot of my shots were taken with a coolpix (soon to be replaced with an LX3) because it was in my pocket...
i do not feel that my pictures now suffer in comparison with my earlier work, the quality of the G1 compares very well. i am happier now because i actually carry my kit in my pocket/bag and its not sitting at home gathering dust. i really believe that for my needs the less kit the better is the way to go...
Similar situation to above, D90-D40x, grabbed the 40x most of the time . . . small, light, convenient.
Pick up the G1/14-45mm this morning! I have sold most of my Nikon gear, but have a D5000 body and 18-70mm lens, why? . . . Cant get down and dirty any more so need the flippy-flappy screen. Keeping one foot in the DSLR camp for the time being.
Saw the opportunity to help my partner with the G1, she has restricted mobility, and uses a Canon A640 compact on a Monopod. The animated screen on the G1, low weight and super picture quality fit well with her photographic needs. I can look over her shoulder and help with settings and composition, a shared hobby in every sense
