Anderson" <[EMAIL PROTECTED]> Subject: PK-3 on N90s [v04.n151/1] Message: 1 The N90s manual says that the PK-3 ring cannot be used on the N90s. Why not? Will it cause damage? Can the PK-3 need to be modified to fit? <<< Ths PK3 is a non-AI accessory. You cannot mount it to the N90S without (potentially) causing damage to the camera, the extension tube, or both.. It might be possible to modify it (make it AI'd). You must also consider whether the PK3 is compatible with AI lenses (all AF lenses are also AI). If it is not, then both sides of the PK3 need to be modified. Frankly, I would not bother with this old piece of gear. Just buy its replacement the PK13. Jim
