    Yup, it applied to all lens as long it used on a DSLR with 1.5x crop factor..
    Is it the same kit lens that come with the D70 ? if it is, I heard it cost S$400-500 ?

    As you mentioned.. Nikon DSLR has a 1.5x crop factor.. so a 18-70mm will become 27-105mm when used on the DSLR...

    Since the Nikon DSLR has a 1.5x crop factor as compared with the 35mm SLR, so if DSLR used with the 18-70 lens, it will be comparable to a 27-105mm of the 35mm SLR. 18x1.5=27 and 70x1.5=105....

    Anyone correct me if I am wrong....

    The angle you see will be that of an equivalent 28-105mm, but the perspective will remain at that of the original focal length.

    If you take a picture of a person at the shortest focal length (18mm), he will have the same oversized nose compared to shooting at 18mm on 35mm film. The only difference is that the picture in DSLR has been cropped due to the smaller field of view on DSLR.

    If I am not wrong, the DX designation means that the lens was designed to work with the 1.5X crop factor of the D70... which means that if u use it with the D70, u're fine.... if the D100 has the same or longer crop factor, it's ok, but if u mount it on a 35mm film SLR, then u're going to get a circular image on the rectangular 35mm negative.... cos the lens is designed to work with a 1.5x crop factor...
