I have had one of my mounts do that,where you unscrew the 3 grub screws and it leaves you with that slighly angled piece still attached too the lens,in this case the possible converter. I can't remember what lens it was that gave me the trouble or I would go and have a look.

It may also be one of those odd 44mm (I think it was that mm ) threaded lenses like the Tele tokina, which uses a similar silver mount that you are having trouble with.


Mo that sounds like something akin to a "standard" YS mount situation. Should that be the case, manufacture by Sigma or Sun is suggested.

Tom ,did you manage to get the "ring" off the convertor?

I was just about to type "no" when a thought occurred to me.
So had another go ............. and voila - it started to move.
What was firmly stuck fast before - now (with copious rubber bands for grip) screwed apart.
Here it is:



Only one little problem - the thread is sort of M42 but not quite.
It screws on for about one turn and the stops tight.
I cannot screw an M42 rear lens cap on it either.
see here:


So what thread is it - M42.5? Very Happy

Undaunted, I took this non registering lens out for a trial.
Min focus distance is about 5 metres now and I wasn't game to try it any further away.
However, it is no slug.
Here are some images wide open - focus was difficult so forgive that.




Now, if I can figure out how to get an adapter onto it fully, it may just prove to be a very useful lens.
In the meantime ...... Who made it I wonder?

OH

Did you try the T mount on that part? They are both 42mm, but the thread pitch is different so one doesn't fit the other.

I would do what elliot suggested and try the silver T mount...and hopefully it will fit.

Yes, what you have there is a standard t mount lens.
The lens side thread is m42x.75 pitch vs m42x1mm pitch for the camera thread.
If you can't unscrew the mount from the teleconverter any m42 t-mount will do. They are cheap and readily available.

Thanks luisalegria.
The silver mount that is on the converter will not work on the lens.
I will search for a suitable adapter.
Would one of these be appropriate:

I am still wondering if that Silver T mount is like the odd threaded Tokina mount?


PostPosted: Thu Apr 03, 2014 10:04 am    Post subject: Reply with quote

Yes, exactly that.
You could get the m42 one, or whatever your actual camera mount is.
I also think that the silver ring on the tc screws off, though it may be on very tightly.

No, it is only held on by the three grub screws.
It isn't threaded and sits on the flat flange as shown in this pic.
I have ordered a threaded T mount in PK finish.

I have been looking through old Australian photography mags hoping to find any reference to a Listar lens...no luck so far.

I confess to clicking on t his thread hoping for a Red Dwarf reference.

It was fun watching you guys work out what was what I confess Razz

I'm not 100% sure but I think I've seen a very similar looking 135mm lens with same doubleaperture ring (but star-like aperture shape) labeled as "Komura" on a flew market.

Haha
I think that the lens consists of two parts - cripple and idiot which joined together was supposed to produce a cat - odioptric lens similar to one to be made by the Kryten company.
Unfortunately everything has been in stasis for a very long time and the only surviving example of this lens is a Listar.
I am sure that there are two curry stains on the barrel ...................

I'm late coming into this discussion, but doesn't the lens remind us of the old 135/225 F2.8/5.6 'Twin Tamron'? The style is different but the idea's exactly the same. Back in the early 1960s I had a 135/225 f4.5 of almost exactly similar styling as this lens, same aperture scales, but with more chrome trim. I think the brand was 'Sankor'. Not sure if that helps or just muddies the waters still further . . .

The Tamron twin tele/converto/etc (they had various names) set is quite well known, several members here have them, and I myself have had 6-7 copies of different variants at various times.

There were two basic versions, one a tiny 135/4.5 and the other a 135/2.8 both with matched tc's. The small one was made in black, zebra and bright aluminum finishes, and in several brands. The big one did not have such extreme cosmetic variations. There are quite a few posts here on these.

This looks like it is a matched set indeed, but does not look at all like any known Tamron product, and certainly not like these two lenses. It is someone else's matched set, and quite uncommon.

Komura certainly made lenses that had a similar layout, but this does not look like a Komura product either.
I have had several old Sankors, and there were apparently two major variants of their 135/2.8s, but neither is at all similar.
In some ways it reminds me of a Kyoei, but feels not quite right.
If I had to choose a most similar lens I would have to say maybe Kawakami/Kawanon, but I would be speculating.

And old preset Tokina also, which are extremely similar to Kawanon. The basic structure closely matches either.
But both would imply a considerable cosmetic variant here. Totally redone focus ring and preset rings.

Thanks for the feedback fellas.
To make it a little easier, here is the lens on its own without the distraction of the converter.
It is yet to have a T mount fitted.





The observation that these are a matched set look to be on the money as well.
Here is a re-connected view and the knurling is identical as is the Lens Made in Japan script

OK, a T mount has finally arrived and fits like a glove.
And so I took it for a quick spin.
Point it anywhere but up and wide open it is not too shabby - see first pic.
Point it anywhere near horizontal and - well what do you think.
It gets worse as it is stopped down.
Number 2 and number 4 are wide open. Numbers 3 and 5 are f5.6
Hmmm ...............

Ha - I have become so accustomed to shooting without a lens hood that I forgot just how badly some lenses behave without one, and how well behaved they can become with one.
Here is take two with suitably shielded lens.
Much better I think.
Again these pairs are shot firstly wide open, then @ f5.6

Always, always use a hood, the bigger the better.

Yes sensei. Very Happy
Here is a 100% crop of number 6 above.
This lens is not too shabby at all.

Being in fact Sankor (E serial). And possibly Sonnar design (many small separations between glued elements can be seen).
