    Is there any real disadvantage to this besides the lengths being 1.4? times longer on the crop body???

    I am looking to possibly get some new lenses and I know I will use my D90 for a long time but when I upgrade it will probably be to a D700 or something. Is it worth getting the full frame glass now and just dealing with the off length or should I just get DX glass and sell it when/if I upgrade??

    Focal length is the same whether the lens is DX or FX.

    Glass holds its value pretty well (as long as you buy decent stuff) so selling it off shouldn't be a problem in the future. :dunno:

    If you have the cash for it, go for it. You can also pick up a cheap nikon slr and shoot some film.

    what? i thought any lens on a DX gets multiplied by the crop factor

    Well, it does. But a 35mm FX lens will act just like a 35mm DX lens on a DX body. That's all I'm getting at.

    and 24-70 kinda sucks on a crop body unless you have something wider to add on, but it depends what you want it for of course...

    24-70 sucks on FX to...

    other than it being sharp and fast to focus... but I dunno wish it was like 17-55 or something along that lines... 24 just isn't wide enough for me, but the 14-24 is too wide (although I own it, for who knows what reason).

    Just find a good used deal on a tokina 11-16 and nikon 17-55

    then sell them and buy the 14-24, 24-70 when you get the d700.

    if you find a good deal and sell well you likely wont lose any money.

    It is not really multiplication, it is just croped

    this

    the dx sensor isnt as big as the fx sensor, so the dx bodies are essentially zoomed in a little bit on an fx lens, due to sensor size cropping the effective picture from the lens. did I make sense there :o?

    also, I think its also the other way around when using a dv lens on an fx body, the limiting factor in both cases is the "dx" part, limiting the field of view.

    The field of view is reduced so then a 35 on DX has the field of view of a 50-52mm on FX
