Actually, both camera are good.
AFS lens are not that expensive unless u compare trinity.
The AFS 18-55 is cheaper then the 50mm F1.4 or the 85mm F1.4
Lacking the ability to AFD does suck when u can't use the legendary 85mm F1.4, which means there's no point buying that lens when u have to MF, so might as well get the Zeiss version
Also, Sigma and Tamron are coming up with AFS compatible lens.
Can't use the 50mm F1.4 or 35mm F2? Go buy the Sigma 30mm F1.4
Don't have $$ to get the monster 17-55 AFS F2.8? Get the Sigma or Tamron one at almost half the price
You get the idea right?
But of coz, the D80 allows you to use all the lenses, have a grip to look more pro and change less battery, and the number 8 is lucky.
Do you own math, do you own sums then decide which camera suits you the best.
For me, it will always be D3 but I no $$$ have to settle for D300 =/
