I don't have direct experience of this lens -- I am relying on this
news
story: http://www.dpreview.com/news/0302/03021800nikon1224dx.asp

Here's a quote: "The DX lens line is designed to be used exclusively
with
digital SLR's with a sensor size of 23.7 x 15.6 mm (a 1.5x FOV crop
factor),
thus this lens could be used on the Nikon D1x, D1H or D100. On these
cameras it would provide an equivelant field of view range of 18 -36
mm."
