Infinitely adjustable aperture?

[cloud worlds]

Hello,
I was playing around with my Ricoh 35 de luxe camera tonight, the model with the earlier lens, and I tried releasing the shutter with the aperture in between stops; not just at midpoint, but anywhere on the dial, it worked fine! It seems I have a camera with an infinitely adjustable aperture. Great for slide film or any other film, actually. Do any other 50's rangefinders have this feature (intentional or otherwise)?

Thanks

On most of these cameras the diaphragma is coupled to a slider and you can just set that to anywhere you want. For convenience way many lenses have also a click-action on their diaphragma stop positions so that you can "feel" rather then see that you changed 1 stop. 1 Stop means that the light doubles or halves, i.e. going from 8 to 11 is 1 stop more closed and halves the light-amount coming through the lens.

I regulary use these old cameras and often have the diaphragma set between stops.

^ exactly what I was thinking; almost all manual cameras I have used possess this ability, and I use it often.

Technically this feature is continuously adjustable aperture; infinitely adjustable aperture is next big thing industry will roll out after fad with high-ISO will go away 🙂
