The D700 will support all DX lenses in “DX mode” where it basically uses a rectangle in the middle of the sensor to simulate the DX size. This means a loss of resolution, however, down to I think 5 or 6 megapixels (can’t recall the exact number) So they work fine, but the camera becomes half the resolution.

Also, you should consider the real effects of a larger sensor. You certainly will get better high ISO performance and cleaner images, but you also lose focal length. If you shoot sports, wildlife or any kind of action shots, especially in daylight, the D300 could make more sense in some ways. There is also a lack of high quality, reasonably priced FX lenses from Nikon right now. Consider all sides of the story.

Just curious, I have the DX 10.5mm….what happens if you attach it to a D700? I am very tempted to upgrade my D300 after reading your review and Scott’s review…but I am not as lucky as you to have a wife that understands these things so well especially since my D300 is only about 6 months old….

Cheers,

Scotty
