I am certainly a novice when it comes to Nikon, but I did pick up an F4 on eBay. For $350 I couldn't pass it up. My Olympus lenses are suscumbing to sticky apertures, and I figured I should shift gears to a model where I can still buy new lenses. My jaw hit the table when I saw the going prices for an F4. HOWEVER, I will still keep my trusty Koni properly exercised. Hard to give up the film size. Discovering the range of lenses available for a Nikon is mind boggling, coming from a system that offers 4 lenses.
