at first

I’m sorry

Because we can’t speak english

I am using DeepL translate, so it may be a strange sentence,

but I would like you to understand

Thank you

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.

I have tried to write the above as clearly as possible.

It is difficult to determine this by name alone, so I would be
grateful if this column could be of some help.
