Thanks Great info!!!
Anyone else?
Every Nikon lens made since 1959 will 'work' on a D40 or D60, they have an f-mount just like every other Nikon. Some you will have to manually focus. Some you will have to manually meter and manually focus, and some will do all of that for you. If you look in the back of your camera user's manual it will even tell which ones are which.I think everybody has said it right. Both the D40/60 and the D300 have dx size sensors. In the end you will have more lenses that work with the d300 over the d40/60 due the d300 having the focusing motor in the camera itself allowing for use with just about any Nikon made lens since about 1980 or so. As stated above, If a lens works wit the d40/60 it will wrok just fine with the d300.
Cheers
New Question.
What lenses are Great for Weather? which I guess is the same as Landscapes.
Which would be great for Automotive pictures? I guess that would be close to Portraits?
