The lens is very easy to use and should last forever. Mine is about 6 years old, has seen over 50,000 photos and works like new. Because it has a very simple autofocus mechanism, it will last as long as any other lens without an AF motor (the camera should have one). Used on D50, D70 and now D90. It is the lightest and most durable lens made in Japan. A NOTICE. There must be a focus pin on the camera body for autofocus. Samples will be uploaded shortly. This is a DX camera lens but can easily be used on an FX camera (full frame) with a focal length of 15mm.
