The 35 and 50mm f1.8 lenses are totally different lenses. 50mm on DX is approx 75mm which is approx double the focal length of the 35mm. 35 for DX is more of a "normal" lens whereas the 50 is more of a portrait and medium tele lens.

Anyway having used both, I prefer the 35mm in terms of image quality and a smoother bokeh. At f1.8 you will see the big difference.

That is inaccurate  , refering to the info posted on the first page of this thread:

"While for the "AF" or "AF-D" lens from Nikon, it still can be mount on the camera, but since there is no AF motor in both the camera body as well as the lens, then the user have to work on for manual focus ONLY. On the other hand, the medium to high end of Nikon camera body will come with build-in AF motor, hence it allow the user to achieve autofocus through the camera's motor rotating the lens' element."

err...we say 50mm is 75mm on full frame because our camera is DX, so our camera got crop factor of 1.5...and 50x1.5=75mm...full frame camera are more expensive such as D700, D3, and D3x

DX camera is 1.5 crop factors at sensor
if using 50mm lens
means 50mm x 1.5 = 75mm

while FX camera is full frame. there is no crop factors therefore using DX 50mm will be same as FX using 75mm

50mm 1.8 got high 2nd hand value leh
