Filter size: 52mm

Depth of field scale for f/8, f/16, f/22, IR index.

This lens is available marked in cm and mm.

The version marked in mm is not to be confused with the newer version, which is supposed to have less chromatic aberation. The places I usually buy used lenses from (Adorama, BH, KEH) are not good at distinguishing between the two.

The older versions have serial numbers below 850000, the newer version have serial numbers above 865101. The older versions have 9 or 6 bladed apertures, the newer version 7 bladed. The older versions are always marked Nippon Kogaku (NPK), the newer versions can be marked either NPK or Nikon. The older versions have a minimal aperture of f/22, the newer version have a minimal aperture of f/32. The older versions have larger aperture rings and slightly smaller focusing rings than the newer version, which has much more silver showing.

Very early samples can have nice rounded 9-bladed apertures:

Here are the three 135mm non-AI lenses:

This is a fantastic and inexpensive lens. If you want to do color work the newer version might be a better choice.
