I agree with you 100%. I've had the problems that have been described here since I bought my D100, and it came with version 2.0 firmware. Why all the 'auto' setting if no standard "sharp, well exposed photograph" can be produced in a 'snap shot' mode. Why not, what was Nikon thinking?
I've learned a great deal from this forum about the D100 and things are getting better but we'll see.
