New Asahiflex Adapter

[Univer]

Hi All,

I'm cross-posting this information here and in the "Buyer Sources" subforum, just to make sure it reaches the maximum number of readers. If it belongs exclusively in one place or the other, I hope the Admins will delete the redundant thread.

I wanted to let folks know about the availability of a new adapter for Asahiflex (37mm thread) lenses. It's a simple M37-to-M42 threaded step-up ring, similar in principle to the rings used to adapt 39mm Zenit lenses to M42.

There have been other Asahiflex adapters available, of course. There was the factory M37-to-M42 adapter offered by Pentax back in the day, of course; that adapter has been duplicated by others over the years. I own one of the copies, and it works well, but - as I recall - its thickness does not allow for infinity focus. (That's not a criticism of the copy; my understanding is that the same was true of the factory model.) And there was a custom M37-to-PK adapter offered some time ago by a former MFL member; I have that one as well.

What these little rings have going for them is simplicity and low cost; it's easy to leave them on one's A-flex lenses all the time (that, in turn, makes it easier to fit a rear cap, if one doesn't happen to have an original 37mm cap on hand).

Another side benefit is that they will also work on Tamron's so-called "Mini-T" lenses: the first generation of T-mounts, using a 37mm screw thread. In my case, the only Mini-T adapters I own are Exakta (somewhat useful) and Miranda screwmount (not terribly useful). This new adapter allows me to fit a short M42 extension tube in place of the proper Tamron adapter, approximating the correct register distance and greatly extending the adaptability of the lens in question.

(Because eBay listings have a finite lifespan, please note that the seller's eBay username is ramir73.)

The adapters are well made and finished, and the seller is gracious and responsive. I should add that I have no connection to the seller, other than as a satisfied customer.

Hope this is helpful!

Cheers,

Jon

What a coincidence!
Yesterday I ordered one of those, to try to build a M32.5 to M42 adapter for my enlarger lenses.
But my step-up from 32.5 to 37 has the upper screw on the wrong side
Anyway I'll keep it for the case I can find any Asahiflex lens.

Regards.
Jes.
