I have a friend who has the nikon 35mm F1.8 (DX) lens and we were curious to know how it performs on a full frame(FX) camera, and whether the vignetting will be severe in FX mode. After testing it for awhile, yes, vignetting is indeed quite severe, though if shot at F2.8 and with the camera's in-built vignetting control set to "High", it can be quite acceptable, especially for close focus subjects. If you know the limitations of this lens on FX camera, I believe it can really take great pictures, especially it being a very sharp len. Its sharper I feel, than the 35mm F2(FX) lens due also to the very precise AFS focussing, and also has better corner sharpness. Using it at F1.8 or more than F8, however, creates the dreaded severe vignetting, so if you have full frame, using a FX lens is still more versatile. Here are some image samples from some casual snapshots with that lens, all shot at F2.8 and with Vignetting Control set to High. Pardon the uninspiring pictures, they were taken on a dreary and cloudy day, and were unedited straight out of the camera except for resizing.

After serving me for a couple of years and producing some of my favourite pictures, I have decided to sell my Nikon 50mm F1.4 AFD to get the newer 50mm F1.4 AFS last week! Initial impressions of the AFS as compared to the AFD were slightly slower focussing(not really a problem for me) but higher accuracy(important especially wide open where DOF is paper thin!) and hence higher hit rates per shot! Optically wise they are very similar, from the initially impression I got, just maybe a little bit sharper and with less chromatic abberations... All in all, its a worthy upgrade if you use the 50mm range a lot like I do. Stay tuned in the future for some image samples. Cheers!
