but I would like you to understand
Thank you
In this column, I will discuss a discovery I made in the design of aperture rings for film camera manual focus lenses.
In previous columns I have written about the focusing ring design of film camera lenses, and I have discovered that even the aperture rings on manual focus lenses differ from manufacturer to manufacturer!
We will refer to the lenses on sale at our vintage shop Japan Inc.
Minolta MC ROKKOR-PG50mm f/1.4

MINOLTA’s aperture ring (the white numbered 1.4, 2, 2.8, 4, 5.6, 8, 11, and 16 on the bottom of the lens) has a single groove design and is completely different from the focusing ring on the top.

Nikon’s aperture rings (the 22, 16, 11, 8, 5.6, and 3.5 sections at the bottom of the lens) have a finely designed shape that is somewhat different in design from the focusing ring.
The design of the aperture ring is as comfortable in the hand as the focus ring.

In this article, we have looked at the aperture ring design of manual focus lenses.
We discovered that, just like the focus ring, the aperture ring also shows the individuality of the manufacturer.
Stay tuned for the next installment of our Discoveries series!
