A series of easy-to-understand explanations about lens mounts!
In this issue, we will discuss Nikon’s F-mount on 35mm film camera
lenses as clearly as possible.
Nikon’s F-mount began with the Nikon F film camera in 1959
The mount has been in existence for more than half a century.
In general vintage lenses
I will Introduction using Nikon F-mount lenses sell by our company
Vintage Shop Japan Inc.
The type introduced here is
Nikon Ai-Nikkor 300mm f/4.5
Nikon Ai-s NIKKOR 28mm f/3.5
These are two different lenses
The designation in Nikon lenses
The “Ai” or “Ai-s” that comes after the manufacturer’s name is not
clearly indicated on the lens.

Therefore, we judge it by its appearance.
Both “Ai” and “Ai-s” have the same nail shape.

Then check the grooves of the mounts.

Check the numbers above and below the aperture section.

The “Ai” next to the manufacturer’s name is a system that
automatically informs the camera of the maximum aperture
value and can be used only in aperture-priority mode.
In addition to the “Ai” type, there is also an “Ai-s” type.
The “Ai-s” type lenses can be used in aperture priority as well
as shutter priority and program mode.
