I already posted a brief comparison of D80 with D40/40x in D80 thread, can I post it in here again!
I hope you all dun mind ya!
D40/40x = smaller body (suitable for smaller hand user), 148 g lighter than D80, only can autofocus with
Nikkor AF-S lenses and
Sigma HSM lenses (limited lenses to choose from if you only want AF and usually more superior and expensive lenses due to built-in focus motor in lenses), suitable for hobbyist that's not keen into having a lot of lenses to change or to choose from.
Below is the list of most used lenses compatible with D40 Wide-angle lenses = AF-S Nikkor 12-24mm, Sigma 10-20mm HSM
Macro lenses = AF-S Nikkor 105mm VR, Sigma 150mm HSM
Normal range fast lenses (f/2.8) = AF-S Nikkor 17-55mm, Sigma 18-50mm HSM
Prime lenses = Sigma 30mm f/1.4 HSM
Most preferred lenses to bundle with D40 = Nikkor 18-200mm VR, Sigma 18-200mm OS, Nikkor 18-55mm + 55-200mm VR
p/s: D40/40x also can use other non AF-S or HSM lenses, but cannot autofocus, you'll have to manually tweak the focus ring to focus!
D40/40x user = entry level body but bundle with mostly superior lenses!
D80 = bigger body, heavier, have flash commander mode, have two mode dials, no restriction on lenses (this is the cause of never-ending buying list

), suitable for hobbyist that can have unlimited lenses for upgrade.
Below is the list of most discussed or most used lenses for D80: Wide-angle lenses = Nikkor 12-24, Sigma 10-20, Tokina 12-24
Macro lenses = Nikkor 60mm, 105mm VR, Sigma 70mm, 105mm, 150mm, Tamron 90mm, 180mm, Tokina 100mm
Normal range fast lenses (f/2.8) = Nikkor 17-55mm, Sigma 18-50mm, Tamron 17-50mm, Tokina 16-50mm
Prime lenses = Nikkor 35mm f/2, 50mm f/1.8 & f/1.4, 85mm f/1.8 & f/1.4, Sigma 30mm f/1.4
Just my 2 cents!
