    Default Can Nikon D90 uses Nikon AF 20mm f/2.8D?

    Hey guys, when 20mm is fit onto D90, the angel of view will it be reduced? because from i saw on nikon's website it says this

    94 (FX-format)
    70 (DX-format)

    does it mean that the photo will be cropped or only when you look through the view finder?

    i need your advice. Thanks! =)

    Of course. The D90 is an aps-c sensor, so it will be like a 30mm lens. This aps-c crop applies to ALL lenses, including your kit lens.

    put in layman term, DX sensor are smaller than FX, so see less area if using a same lens compare the FX body.

    Yes you can. All you'd get ias a 30mm focal length equivalent view on the 35mm (or full frame) format.

    Just remember that the crop factor will apply to all lenses. Multiply the lens focal length by 1.5 to get the equivalent view on film/full frame.

    Yes, you'll get an effective 30mm F/2.8, 70 angle of view.

    And yes, it is able to auto-focus too!

    I suggest you actually try to use your camera. With any lens you use, your viewfinder will present you with a cropped view.

    WYSIWYG. What you see through the viewfinder of the Nikon D90 is what you will get. However, when you mount the same lens on a FX body, like a D3, you'd notice that the angle of view is wider. That's all.

    Not quite... D90 only has a 96% coverage.

    To TS (Sylvester88),

    Digital SLRs are designed to present a view that is (or ALMOST is) what you'd get on the captured photograph. As bro Blur Shadow stated (before he was corrected), WYSIWYG... well, almost...
    oh btw it's an ANGLE of view. The angel is the one with the wings...

    Just in case you didn't know, there are a number of lenses which are specifically designed for DSLRs that use the DX-sized sensor. Such lenses when used with an FX camera (like D700, D3, D3X) produce an image which does not completely cover the FX frame. So you see black corners.
    An FX lens (any lens without the DX nomenclature) can be used on a DX camera, but not the other way around.

    if you still dont get it, let me try simplifying things.
    DX body (1.5x crop factor) FX body (1x crop factor)
    *neglecting the very slight difference every viewfinder has*
    when you attach the same 20mm to both bodies,
    DX body 1.5x20mm= 30mm FX body 1x20= 20mm
    and What you see thru the viewfinder is what you get.

    Hope this helps.......

    The crop will also be present when you take an image.
