One more 400-560mm f/6.8 question

This question is about the 14182 tube, when using this tube on the 400 or the 560mm will it still allow the lenses to focus to infinity?

No - that is the macro ring. (641-396 cm)

[luigi bertolotti]

No, it's an extension tube to focus at shorter distances than the standard: it effectively elongates the std. 11905 attachment tube.

So it would ALMOST be like using the R tube on the visoflex with a 22228 adapter, that will also not focus to infinity but allow closer focussing. Any ideas thoughts?

Could be... probably not the same.. but M tube is shorter than R tube, and 14182 is surely longer than 22228, so can be R (11906) + 22228 nsdf M (11905) + 14182..but this is of no great significance... let's say that if you have a Telyt with R mount and a 22228, you get a "someway macro" lens and an "infinity-only" lens (22228 direct on M, no Viso in the middle).

 

Of course, with a M8/9 one can go on trial-by-error with 22228 only... check the LCD image then adjust focusing.... (I tried this way with my Olympia Sonnar 250 with Contarex-to-M adapter... great lens,,, but VERY boring... )

 

nsdf=not so different from

The extention tube is about 3 inches. The difference between the M and R is only around an inch, exact if you go to my first answer.

 

If you have an M and want to use it on R camera, 14167 m to R adapter is the proper way.

I have R lenses and want to use them on my M till the solution shows up or till I am able to spring for a Sony A850 and change one of the mount tubes over to the sony mount. But till then I wanna use them on my Visoflex. M tubes or are not showing up and those long lenses that are showing up in a M mount - 2 on the bay now, one is buy now like 2500.00 and other is around 6,000.00 for a 400mm that you can get in a R mount for 450.00 to 900.00. I don't think those on the bay will sell for that kind of cash. My first M mount a few years back used was under 400 dollars. I even have a wanted add on the forum, buy sell no luck there

Call Leica USA and ask if they can convert the R mount tube to Viso.

[leicanut2]

The R tube would have to be cut shorter, may be possible would loose the filter slot but if I remember right the M tube does not have a filter slot.

I will call them and see if it can or has bin done.

Thanks Doug.

 

Just called I did could not get threw so sent them a email. Jan

The tube does not need to be cut at all. The rotating R mount is replaced with a rotating Viso mount. Other than the rotating mount, the tube needs no alteration at all.

[leicanut2]

Doug,

 

I am looking at the R tube right now that would give me a M mount but because the R tube is longer than the M it will not not allow me to focus to infinity on the Visoflex.

I've had both Viso and R mount tubes (I no longer have the Viso tube). The only functional difference is the rotating camera-end mount. When I used the 14167 Viso-to-R adapter with the Viso mount tube infinity focus was not a problem.

[leicanut2]

Yes, but I am going the other way r to viso m I have a r to m adapter 22228 and can't focus to infinity with that set up at all. And the 22228 adapter R to M is even longer than the 14167.

You don't need to use the 22228 if you can get the lens mount tube converted. The lens will fit directly on the Visoflex, no adapters required.

[leicanut2]

The leica 14182 tube they say that with that tube on the 400 or 560 on a R camera you can not focus to infinity, well because the r tube is longer even if the mounts where changed than a m tube it would be just like using the tube on the r camera only it would be on a visoflex. Will not focus to infinity.

I really would try if they email me back that something can be done.

The leica 400 and 560 and even the scope will focus with the viso on a M9 but not to infinity.

The R mount tube is longer than the Viso mount tube because the rotating part of the tube is longer on the R version. The flange on the Viso version tube is the only thing to the rear of the rotation point. The additional length of the R mount plus the additional length of the 22228 would prevent infinity focus, just as if you had used the 14182 or any other extension tube.

 

I don't know who "they" is but from personal experience using and repairing the f/6.8 and f/5.6 Telyts over the last 30 years I know this equipment inside & outside: if Leica can replace the R end of the tube with the Viso flange, no cutting will be needed, the filter slot will still be there, and it will focus to infinity on the Visoflex.

Jan,

 

I believe the filter slot in the previous post's referenced images is just to the right of the M Tube labeling.

On my copy of the 400 f/6.8 M version you just slide back the little cover and there is the filter slot.
