i have a nikon d5000 and i know it doesn't have a built in motor and i would have to manualy focus, which wouldnt be a problem. Are there any differences at all? Is one better than another?

The main difference is that with the second link you posted (the AF-S 50mm f1.4G), you will not have to manually focus. Any lens marked AF-S will work without a hitch on your D5000. Other than that, it's a newer design and might be a smidge sharper, but both are fantastic lenses. If you had a D90 or above, I'd save the $100 and get the older lens. But with your D5000, I'd get the newer design.

Personally, I'd go for the AFS 50mm f/1.4G because it autofocuses. Manually focusing a lens with an aperture as wide as f/2 (or bigger), is a real pain in the but because the viewfinder is only designed to give the depth-of-field of a f/2.8 or f/3.5 lens, meaning that the tiniest bit of focusing error will translate to a majorly out-of-focus results.

If you still don't mind manual focus, the older AF Nikkor 50mm f/1.4 is cheaper and has optics nearly just as good. It's a tiny bit less sharp wide open, but gets close or even to the newer AFS lens by f/2.8

If can afford the second one, go for that, It. Difficult enough shooting such a lens wide open with an autofocus body.
Optically the performance will be very smal.

If manual focusing is not a problem get the cheaper one. When shooting at f/1.4 for detail work, you would be manually focusing anyway.

There will be a subtle difference in picture quality due to the additional coating of the more expensive version. The hundred dollar difference would be more justified on that internal motor I guess.

Save yourself $105 and go for the 'motorless' version.

Autofocus lenses sometimes have a tendency to 'hunt', during which time you could lose an all-important shot.
