Re: FX/35mm lens on a DX body?

Part off topic, any wide angle FX lens usually performs better on DX at wider apertures than on FX.
Optically it is not possible to have top corner quality wide open on FX lenses.
The not so good FX corners get cropped out on DX.

Interestingly the recent 35mm f1.8 DX is shown as performing better on DX at f1.8 than the 23 year old optical design 35mm FX f2 on DX in Nikon's full aperture MTF information.

Many problems turn out to be a lack of intimate knowledge of complex modern camera equipment.
