Fotodiox Pro Lens Mount Adapter w/Aperture Dial, Deckel-Bayonet, DKL Lens to ...

[Sumarongi]

I've bought a Fotodiox Pro Lens Mount Adapter w/Aperture Dial, Deckel-Bayonet, DKL Lens to xxx, but: I do *not* have any xxx camera body.

It looks like this:

Question:
Can I *easily* replace the flange with another flange, e.g. taken from an old extension tube, or is that not really feasible?

Thank you 🙂

Dear Peter, I can see you're viewing this thread 😀

It's odd that you should post this thread. I am in a similar situation in that a DKL mount adapter arrived for me yesterday and I have no DKL lens (yet). So I am kind of your mirror image

The other differences between me and you is that I cheaped out and bought a cheaper version of the adapter (though I must say that it looks and feels very well built) and the adapter I bought is to adapt to a Nikon mount not directly to a mirrorless camera.

I did this for two reasons. The first is that I kind of like the idea of using say, Retina Reflex lenses on a Nikon body, and the second is that as I already have Nikon to M4/3 and Nikon to NEX adapters I so can stack adapters saving me the cost of buying two extra adapters and killing three birds with one stone.

What seems so particularly coincidental however is that both of us have end up temporarily with a relatively unusual adapter but no means to use them. I must say though that my problem is cheaper to fix than yours given X bodies cost much more than old Retina lenses. 🙂

Arrgh I had no idea this was possible.......I must watch what I am doing 🙂

Yes, odd in deed —— like our weird enjoyment of «The Omen» haha!

Haha! Not really a difference, it's again a parallel I'd say, because so did I previously, and: my cheapo «DKL—AI» adapter is somehow ... weird, again! Just recently I've written:

It's absolutely not unusual that there's no half stop between f/22 and f/16; this was standard until recently, erm 1970s, or so, before microchip-nonsense and cheapo plastics were built even into expensive lenses. —— Roger Hicks could explain the reason why, do you have any of his books? I think it's explained in his book «A History of the 35mm Still Camera».

Well ... my otherwise nameless «DKL—AI» provides half stops from the (erroneous) «1.8» only to 5.6, and from 5.6 to 22 it's just full stops. 😕 —— How does your adapter behave regarding half/full stops, Peter?

So, I wanted to know why the unusual behaviour, and of course, when I unscrewed the bayonet and the aperture mover-screw (whatever the correct term might be), of course I repeat, the tiny but eminently important ball *immediately* vanished somewhere a couple meters away, in my wife's study's parquet floor, gutters, my tomcat's stomach, or whereever :bang:

—— And just now, :bang: after I've already ordered the new and much more expensive one above that additionally has a bayonet that I will have to replace :bang:, I discovered that I can actually very easily repair the cheapo adapter: I managed to replace the missing ball with a tiny piece of a paper-clip! 😀 ——

yes!

Similarly in my case: I have e.g. a Nikon F > Canon FD adapter, and then a Canon FD > LTM adapter, and so forth 😀

I have this adapter for my XT-2 (and a 50mm f1.9 Xenon plus 35mm f2,8 Curtagon). The adapter does not allow complete aperture opening on the Xenon.

Thank you, I thought as much!

OTOH, I'm not sure whether this is necessarily the adapters's fault; I've seen exactly the same behaviour, mounted on an original camera, Retina Reflex S, e.g.: when one has dialed the full aperture, nevertheless a little portion of the aperture blades are visible. Hmm, another mystery.

As I said in a previous thread I also have an issue on my DKL to M42 adapter with the Xenon. In that case the aperture sticks sometimes. The Xenon seems to work fine on my Retina Reflex IV.

In terms of the Fotodiox adapter, they said I could cut the slot a little longer to allow full opening.

The slot where, as I've called it, «the aperture mover-screw» has its home?

Yes.That is what I am referring to.

 

[Sumarongi]

Now I understand 🙂
I guess a very thin round file, or a tiny piece of emery paper, perhaps even a simple cardboard nail file?, could be the remedy for the problem in question?

 

[Sumarongi]

Today, the Fotodiox Pro Lens Mount Adapter did arrive —— alas, my simple-lens-flange-swap-plan isn't feasible 🙁

Write-up, plus pictures why this is so, will follow soon.

All those parallels, that's hilarious.

In answer to your question mine seems to do the same - half stops to f5.6 then full stops. Weird.

When disassembling any camera or lens gear with their myriad of tiny screws, springs, ball bearings and other parts I have learned the hard way to first lay down a white towel on the work surface before I commence. White, so I can see anything that falls and a towel (or similar fabric) as it's rough surface tends to discourage things from bouncing when they land and disappearing on the floor. It has saved my neck numerous times. Your cat like mine seems to have a penchant for small objects on the floor which being in her territory all then become her playthings (or food).

The above arrangement also helps me lay out the parts from right to left to remind me of the order in which they must be reassembled when the time comes secure in the knowledge that a careless bump is not likely to disorder them too much. Is this excessively anal retentive? Well all I can say is that the annoying thing about lenses is that there are several ways to disassemble them and only one way (mostly) to put them back together. Grrrrrrrrrr 🙁

PS Having done the rounds of USA (my God the USPS is inefficient) my Retina Reflex 135mm f4 Tele Xenar lens has finally landed in Australia two days ago, cleared customs and is in the hands of local courier according to tracking info, and I am hoping for delivery possibly as early as today. It's the parallel sided version not the chrome funnel shaped one. Rather looking forward to is it as I have another Schneider Tele Xenar in exakta mount (a 105mm f3.5) and it produces lovely images.
