Re: Understanding the difference between these two FX lenses?

The first (IF, AF) requires a camera body with built-in focus motor to auto focus. It also retains the old school aperture ring which would be required for film cameras. The D300 has a built in focus motor so AF with this lens is fine. It will meter with all modern Nikon bodies.

The second which is a modern G, AF-S lens has a built in silent wave motor which allows auto focusing on any digital Nikon body. All G lenses loose the aperture ring and aperture is controlled using the command wheel on modern Nikon bodies. The AF-S version also employs VR which can come in handy in low light situations when slow shutter speeds may be required.

Both lenses are FX so they can be used on either a DX sensor such as the D300 or FX sensor cameras.

Hope this helps.
