Jim S. is using the effective FL conversion from a FF camera to a 1.6x crop camera. Coming from 645 platform the crop factor is going SEEM even more extreme than the 1.6x crop factor from FX to DX
60x45 645
36x24 FX
24x16 DX
I\'d HIGHLY recommend going FF ... but, before that, I\'d get the adapter and use your 645 glass on a rented / borrowed DX body (even if it\'s not the D300s). It will only take a few shots at 35mm to see/feel the difference coming from 645. Actually, you can use any 35mm lens on the DX body and see what you get for your cropped images.
I\'m pretty certain you\'ll be disappointed with the angle of view on the wide end of things (compared to the field of view you\'re used to on the 645), but you\'ll love the IQ & convenience, the TONAL VALUES the 645 glass provides on digital is VERY NICE.
Expect that you\'ll augment your 645 glass with 35mm glass on the wide end, but I\'d still HIGHLY recommend going Full Frame. NOTE: The larger pixels of the 700 vs. 300s will let you take better advantage of your 645 glass, particularly as you stop down without showing effects of diffraction.
FF definitely !!
