I have a good friend who dragged me kicking and screaming into the world of digital photography about ten years ago. He was invaluable in helping me determine which lenses to buy. This is the first lens I've bought since initially stocking my camera bag. He asked me for a picture of it, so I thought I would also share it here in the forum.
This model was made from about 1987 to 2000. The mechanism located immediately to the right of the identification plate holds an internal 39mm filter. The lens is optically designed to have the internal filter in place, so I'll be leaving the Nikon clear filter that came with the camera there. When Nikon shipped the lens, a gel holder was also provided for use instead of the filter holder. No gel holder came with my copy.
The item with the designation, "A," located on the focusing ring is a slider that switches between manual focusing and automatic focusing. Unlike the modern lenses, it has no M/A setting that allows you to automatically switch from automatic to manual focusing by simply turning the focusing ring.
The silver knob located immediately to the right of the focusing switch is the handle of a ring that functions as a focusing limiter. Turning the ring to place the dot, as an example, at the 100ft/300m marking limits the hunting range of the lens from that distance to infinity when automatically focusing. I'll probably leave that setting at "Full," which requires the lens to hunt the entire focusing range. Despite that the focusing speed is relatively slow (there is no focusing motor inside the lens), I expect it to work fine for me. That's because I won't be photographing rapidly moving subjects.
This lens was released before Nikon standardized on the use of 77mm filters for its telephoto lenses. This one weighs in at 82mm, requiring me of course to purchase an expensive circular polarizer. UGH!!!!!!!!!!!!!
Unlike the current model that has a minimum focusing distance of about 5 feet, this one focuses only as close as about 9 feet.
The current equivalent of this f/4 lens, which has a focusing motor, costs about USD $1400 when purchased new. I was able to purchase this one, which has no focusing motor, for USD $420. As you can see, it's in terrific shape and it seems to be tack sharp in all but the extreme aperture settings.
If you know anything about this model that would be helpful for me to know, please don't keep it a secret!
