Leica Telyt M f/4.8 280 mm on M10

I'll wake this thread up again, since I'm in the exact same situation.

I got the lens, I got the M10 - but it's all blurry when I mount it of course.

 

I read the answers here, but I get confused - what are my real options? Can e g these rings be used (swedish site, but you'll get it I think)?

Hello Daviden,

you need to move forward your 280 lens about 40-41mm depending on the mount (1mm for the 39 LTM to M mount).

Or like me use the Visoflex III to fill the gap ...to use Visoflex lens which the Telyt 4.8/280 is from this original family (link to the Visoflex lenses (of Wiki).

this list of accessories to have an idea of the complex original Visoflex using ( this link ... )

even then I don't see easily which one to use as 40-41mm ring

or maybe stacking four OUFRO (1cm ring)

Thanks!

I was hoping to get away with just using rings. I sent an email to my Leica AD and asked if it's enough to just go for the Visoflex rings. Then I can have some joy of using them for Macro also, and not just this lens.

Hello,

look at my picture in post #9 : the final component is a ring from Novoflex (you can see the brand name on it) : it is called LEM/VIS and is currently listed by Novoflex, even if different from the old version that I have : the current version is a set of stackable rings : when complete, it has the length of a Visoflex II/III (like my one, which is single piece) ,

At the bottom of this page from Italian dealership you can see exactly your Telyt 280 with the ring set : https://www.novoflex.it/pagina.phtml?_id_articolo=1968-Adattatore-per-Visoflex-IIIII-e-tubi-di-prolunga-in-un-solo-kit!.html  ; Novoflex are well built accessories, no cheap but trustable. Maybe on ebay or similar you can find the previous version like mine... in my opinion it is more nice to use for a long lens, where the need is simply to have the Visoflex equivalent length : the current version is more "flexible" because you can use its single rings as extensions for macro with normal M lenses (like 50/90/135) - they act like the old Leitz OUFRO.

The Visoflex mirror box is a sort of must for lovers of Leitz collectibles 😎 (and mandatory for no-EVF Leicas) but...well... not easy to manage as a ring is 😉

I ordered the Novoflex rings yesterday 😅

Cry once, but quality.  

 

Thanks for the input, much appreciated.

Sorry for not reacting earlier!

I found out that the Novoflex LEM/VIS II causes severe vignetting for the Telyt-V 1:4.8/280mm, which the Visoflex body avoids (to the most part at least).

The following examples were taken with the Telyt-V on an M10 with a opaque objekt immediately in front of the lens. This "dramaticizes" the effect of vignetting but it makes it obvious as well:

First the examples with LEM/VIS II:

at f/4.8

at f/8

 

Now with Visoflex III body:

f 4.8

at f/8

Novoflex changed the LEM/VIS in the meantime, but I am not too optimistic that the new construction avoids the artificial vignetting.

That's strange... here are 3 quick test with my LEMVIS I with Telyt V 280 ... only sign of vignetting is with lens wide open and focused at near distance, and it's anyway rather small (M240 jpg OOC) : indeed, I have the feel that LEMVIS I ,a pure "tube" is probably the cleanst device...

280 wide open - focus set at 6 meters  (in the original unresized vignetting is more evident)

Unresized, top left corner

 

Wide open. focus at infinity  (vignetting negligible even in full size)

 

At f11, focus at 6 meters ... vignetting unappreciable (at infinity, the same)

Totally fine with me. I tend to always add a little vignetting myself in post - in worst case scenario, I can alway crop it a bit.

I did however order the latest version - LEM/VIS-III. So it might be a difference? 

I'll come back and post test photos as soon as I get them. ☺️

it can be, indeed... my one ("one piece") is LEM VIS I, then they made the version made with rings (LEM VIS II) ... then it was superseded by LEM VIS III, apparently identical iirc... maybe they realized the problem of vignetting and made some small reengineering to override the issue...

Yes; the rings of the LEM/VIS II must take the thread of each other ring, therefore they leave less space inside. Even the Telyt 1:4/200mm shows some vignetting with the Novoflex adapter, which it doesn't with the TXBOO, also a "pure" tube. I also tried the combination of the 14127 Visoflex-to-R adapter together with the R-to-M-adapter: the 14127 also vignettes a lot.

Hello everyone,

I reopen the subject 😊

I am looking for help please regarding the use of a Telyt V F4.8 280mm (screw frame) lens from 1963 and my M11 case.

So far, I have stayed on standard focal lengths compatible with this case but I wanted to test longer focal lengths. I am not a Leica world specialist because I entered the brand with a M10 3 years ago and I am not familiar with developments in objectives or technical characteristics.

I have seen several publications on forums of people who had set up their Telyt on M10s.

I bought one or two years ago a kit of Novoflex elongated rings, one of which allows this type of mount to be screwed and insert it into the M mount in the case.

But even in infinite focusing (example, target the moon), I'm blurred ...

Impossible to be clear anywhere at any distance.

I tried every combination (one, two, three rings...): nothing works.

The end of the kit is a LEI-M.

The all kit mesures 41mm.

In short, there is a technical characteristic, a technical explanation that I do not master and for which I would need a lighting (popularization) so that I understand why.

And advice to make my lens compatible with the M11.

I think I'm closed to the solution.

But still far from a answer...

Maybe the right combination would be: the entire kit including the LEI-M ring and a Novoflex adapter ring M 39 lens to Leica M body ?

Reference: LEMLEI

Could you please enlighten me? I am interested in your advice, references etc.

Thank you very much in advance

The LEM-VIS combination is the one that should be working.I see you have it. I would check the lens whether it has been modified in some way.

[jaapv]

I have used the lens(head) on a Televit-R with M-R adapter. Can't take an image, it is packed away with a load of other unused stuff

Hello and thank you for your answer.

I already have this Novoflex kit.

But it doesn't work.

In my opinion, the Novoflex adapter ring M 39 lens to Leica M body is missing at the end of the kit, to complete and reach the 41mm distance required.

The last ring of this kit is made for M mount... So I think that another flat ring M39>M is required.

What is your opinion please ?

Thank you

Eric

Yes, this should work - in principle. You always need the whole thing made up of four separate rings + the Adapter for screw-to M-Mount (LEM_LEI, which is included) as a substitute for a Visoflex body. Though as I described above the LEM-VIS II causes serious vignetting for the 1:4.8/280mm Telyt-V, which the lens doesn't show originally (see luigi's examples with the older LEM-VIS I, which was in one part but isn't on the market any longer). I learned that there is even a new version of the LEM-VIS by Novoflex, which allows you to regulate the lenses position. I don't know this new one - perhaps it does not cause vignetting. 

For me perhaps not the most elegant, but the most convenient version is to use the old Visoflex housing. Fix the mirror in upward position and unscrew the lever arm (which is non-destructive).

Hello and thank you for your prompt answer.

I read your post about vignetting...

I'm going to search for an older LEM-VIS I on the second hand market if I'm lucky enough...

And I'm also going to investigate for this new version of the LEM-VIS by Novoflex, you're talking about.

I really appreciate your help.

Thank you very much.

Sorry, I did not read your entry properly:

If your lens has a screw-mount (my later one has M-mount) I think you need another adapter: 16466 or OUBIO! You fix your lens with screw-mount to the OUBIO, then the OUBIO to the broad front ring of the LEM-VIS, which has an M-Mount, then the LEM-VIS with a screw-to-M-mount adapter (LEMLEI, which is included in the LEM-VIS set) to the camera.

OK !

Thank you.

I will investigate this last solution...

Many thanks

Hello Eric,

Welcome to the Forum.

UliWer is correct.

Because the lens you have was designed to work on the earlier Visoflex I

It requires an additional extension of 22.5mm in order to have the proper focal length to operate with the equipment that you already have.

This 22.5 mm is the length of the 16466 adapter. Also sometimes identified by letter code OUBIO.

If you can not locate a 16466/OUBIO

Any combination of adapters measuring 22.5mm, or just a little LESS, should allow focus from Infinity.

The additional adapter(s) should go in FRONT of the adapters that you already have.

It will need a female screw thread to connect to the lens & whatever is necessary to connect to the adapters that you already have.

Advantages of the 16466/OUBIO are:

It is strong & has a tripod attachment where you want it.

It is NOT a good idea to use the tripod socket on the camera with heavy lenses.

It also allows a person to rotate the combination for both horizontal & vertical photos.   

Best Regards,

Michael

Hello Michael,

Thank you for your answer and the details you gave me.

So, you recommand to put the OUBIO adapter after the all Novoflex kit ?

Because I think I tried to insert the OUBIO adapter straight to the M11 body and it could not fit because of a piece of metal (the one wich allows to connect with a tripod attachment).

Sorry if my question seems curious but it's for the sake of understanding.

Than you.

Kind regards

Eric
