Have you learnt how to decipher the old markings? Before the rubberized grip era, Nikon told up front how many elements the lenses had.
I have compiled a list from several different sources around the net.
The letters signify the number of lenses:
T –Tres (3)
Q –Quatour (4)
P –Pente (5)
H –Hex (6)
S –Septem (7)
O –Octo (8)
N – Novem (9)
UD –UnoDecem (11)
QD –QuatourDecem (14)
PD –PenteDecem (15)
Auto –Automatic diaphragm. Meaning that the aperture is wide open for focusing and the body springs it down to working aperture while raising the mirror.
·C –Coated, that is the lenses are coated with an anti-glare coating. It can be either a single coat or the multi coat still in use today on lenses introduced before nanocoating.
These pre- and suffixes were scrapped in 1974 when the K-series was introduced.
If you find one of these, make sure that it has been converted to AI with a new aperture ring before you try to mount it to a modern body with AI coupling, they can break the coupling prong easily otherwise.
