Do know that the 35/1.8 also works on fx cam bodies on fx mode. Very slight vignetting on wide apertures (f4 and below) but very usable. Sharper than 35/2 and faster focusing too if on d700. If on d3, the afd is faster because of the faster screw drive motor. Because of this the 35/1.8 is fast attaining cult status.
This is a route you can consider if you do not have budget for the 35/1.4
