D700 Keep in Mind FF cameras make your lens shorter
FF 200mm is really 200mm
DX 200 x 1.5 dx multiplier = 300 mm
so prepare to get longer glass
I see an increase in value of Older FF Lens
For example Ritz is packaging it with the 24-120vr
and apparently this lens is worth 600.00 now

I'd like to see Nikon update the 24-120, since it doesn't appear to be well-regarded.
I decided that, for now, my walk-around lens is going to be a 24-85 (the AF-S f/3.5-4.5 version) - I found an "excellent" used one on Adorama. That'll buy me some time to see what else Nikon comes out with (if anything) targeted at full-frame cameras.

Not shorter, just their actual focal length relative to 35mm as full frame. The DX perspective doesn't "multiply" the focal length, it simply crops the image in terms of sensor capture size at 2/3s the original size relative to the 35mm standard. Just remember that you can accomplish the same perspective with either the in-camera DX mode of the D3 and D700, or with post processing. However, the big difference is in the sensor pixel count, and that's where the D300 has an advantage in ultimate resolution for the same field of view. But obviously there are other advantages to a larger pixel in the FX mode, not the least of which is light gathering ability resulting in the superb high ISO performance of the D3/D700 sensor. By the way, this sensor is not a Sony design, but is a proprietary Nikon design produced by an undisclosed manufacturer. The "potential" 24-25 megapixel sensor D3X will likely utilize the Sony one of this size.

200mm is always 200mm.
The larger sensor does make your "reach" shorter to obtain a given crop at a given distance to your subject, but the multiplication factor depends on your history as an camera user.
Remember that the whole idea of a multiplication factor was to provide a visualization tool for folks who had spent years with 35mm SLR cameras. For someone going from 35mm to DX, the 1.5X factor is a useful visualization tool. But there's a generation who have only DSLR experience with DX (APS-C) format so they'll need to use a .75X factor to visualize how their 200mm lens will work on an FX body. For them 200mm will look like 150mm.
But 200mm is always 200mm, it's just a matter of how big the format is behind it.

>D700 Keep in Mind FF cameras make your lens shorter
Though the pther explanations address the fallacy in this statement, from a "non-technical" standpoint, you really should be saying that the DX sensor makes your lenses "longer." If "200mm is really 200m" that's not "shorter" by any possible definition of the word. "200m is really 300m" is "longer."
But again, your focal length never changes, only the crop. You can make a FF with a 1.5x crop easily enough without using the DX mode on the D700. It's called Photoshop
This is my Nikon. There are many like it, but this one is mine!
