The Original FX Trilogy

Back in 2007, when Nikon launched the first FX format DSLR – D3, it also rolled out two new lenses, and bundled it with an older lens; many call these 3 lenses the ‘FX Trilogy”

• AF-S NIKKOR 14-24mm f/2.8G ED
• AF-S NIKKOR 24-70mm f/2.8G ED
• AF-S VR Zoom-NIKKOR 70-200mm f/2.8G IF-ED

Image Sensor: Nikon FX vs Nikon DX

Those numbers work out to be 131% larger area for FX than DX format. More area to pack more pixels resulting on lesser noise.

When you use a DX lens on a FX camera, the resulting image is smaller than the FX image sensor area and you’ll get a cropped picture with lesser pixels and lower resolution. This wastes much of the capability of the FX cameras.

Use Non-DX Lens on Your D700

All non-DX lenses, older AF or manual focus, will give you full frame image on the FX format DSLR.

In other words, non-DX lenses are FX lenses!

You can really get amazingly good picture with the right lens on the Nikon D700! Here’s a video comparing D700 vs F5 using the same 85mm/F1.8 lens. So you see, you can use your good old Nikkor AF lens on the new D700 to get even better result.
