Hi there
You have probably heard of the Hanimex 400 mm 6.3, with at 42 mm thread - but how about a 47 mm thread?
I recently bought a lens with this peculiar non standard thread at the end. I have been searching the WWW for hours, but I seem to be the only one in the world, who has a lens with this thread?
Have any of you ever come cross one of these before?
The adapter fitted at the moment looks just like a T2-adapter apart from the thread size.
It has the same size bayonet as a RE.Auto-topcor 1:1.8 f=5.8cm.
I was hoping to be able to fit it for my Nikon, but at the moment it seems impossible.
In advance, thanks of any response.
Best regards

Well, then I got that sorted. And now to the question of, is it worth to keep looking?
I have read something about that it with a Nikon would be impossible to achieve infinite focus, because of the distance between lens and sensor.
Would you happen to know if that is true?
About the adapter i have at the moment. Is that a Tupcor or am i wrong? |

I have a Vemar lens with the same mount. Luckily for me, it has an m42 mount on the other end.
If you have access to a lathe, what you could do is find the appropriate T2 mount and adapt the inner ring. Then you could glue both inner ring together... or add some small screw thread. A tight fit with some good glue should be enough.
Here's a picture of both mount (and my crappy drawing).

And a crud representation at what it might end up looking like. (imagine the center m42 mount is not there...)

I too had the problem of finding one of these mounts in M42. I done it in the end by buying a small collection of presets and found one in m42 which I now use on 4 other lenses with this 47mm mount.
It can be an expensive way of finding one, but I'm not complaining because I now have a great collection of presets to use.

First of thanks for your quick responses.
@Andreq: Great idea, and I do have access to a lathe Sadly after a visit at the local camera shop i found out that the adapter is to little in diameter. After increasing the internal diameter to fit my inner ring, only about a mm would be left around the edge. And I guess this is to little to hold the weight of the camera within a safe margin.
@Barnaby: Lucky you to find a 47mm to 42mm adapter.
A small collection? You wouldn't happen to have a spare one for a Nikon to fit the 47mm?
@Loydy: Now I just need to track it down
@mo: I might try that |

I got that OM adapter with a very beefy inner ring...
I was about to tell you to get a cheap T2 adapter off ebay, but looking at my T2-EOS, it's true that the inner ring is quite small.
Maybe the ebay OM adapter is beefier?
Anyway it's just an idea, I don't know if it's a good one |

I contacted an astronomers shop, and luckily they had a T2/Nikon adapter with an inner ring of approximately the right diameter.
I'll probably have time to fit it for my inner ring some time next week.
I will of cause make a post with the end result here.
Thanks you guys for the expertise and suggestions. _________________ The worlds best camera - is the one that is ready when the subject is there! |

OK. I'm now back on track with the lens
I received the T-ring adapter from the shop and detached the inner ring. Unfortunately it wasn't beef enough to be adapted for the T-ring.
Instead I decided on making an "adapter for the adapter".
I figured that making a ring of brass with a 47.01mm inner diameter and a 52.00 mm outer diameter would do the job.
However, before making the ring, I found out that the lens reached infinity focus before the focus mark. The lens needed to be moved a bit away from the camera.
To find the right distance I added paper rings in between the adapter and the lens, until the lens seemed to focus correctly.
(I checked this by looking through the lens at a high tower 2-3km from my house and use the focus help function in my camera.)
I found that 7 layers of paper (0.650 mm) solved the problem. However, since paper probably wouldn't be a durable solution, I added a collar to the design of the brass adapter ring.
I glued the brass ring onto the lens-thread with epoxy and now have a fully functional lens with a personal touch.
I'm pretty pleased with the end result and I'm looking forward to be able to take it outside.
At the moment however, it freezes -12 °C (10 °F) outside and i'm not up for sitting out there waiting for a bird to come by
Thanks to all of you for your suggestions
Best regards Jesper

Well done !
The Bird in Flight shot is a proverbial challenge of course.
There are no techniques I know, other than the obvious ones -
- Pre-focus to a fixed range
- Good range estimation
- Lots of shots
