This lens is an interchangeable lens released around 1985
This lens is one of the “A series” lenses.
At the time, the P30 DATE single-lens reflex camera was released, and this lens was the standard lens for that camera.
At that time, the name “TAKUMAR,” which had been familiar from the days of Asahi Kogaku, was no longer used.
The lens mount was changed to KA mount based on K mount.

The right side is KA mount.
It is almost the same as the conventional K-mount, but you can see the contacts for auto.
The body is made of plastic.
Here is a cleaned lens.
The body is used and has scratches and letters like this.

If you shine a light on the lens, you can see a dot scratch near the center of the inside of the lens.

We have not taken any test shots, so we do not know how it will look, but we think it is a good lens for an introduction to film cameras.
Get it and enjoy!
