I love these old Nikkor Non-Ai & Ai lenses: unfortunately since the advent of mirrorless cameras, the price has gone up a lot. There are some bargains, but careful consideration of the condition & most importantly! lack of lens fungus needs to be taken into account. Even a small amount untreated, will migrate to any other lenses/camera you have in your bag. If your storage conditions are not good, high humidity & darkness will promote growth.
