Finally got a Visoflex for my M9; now, what...?

Per,

Don’t worry any over adjustments and shims…. of the five Visos I have have

Viso II,IIa,&III three all were fine.

 

Glad to hear that, indeed! While I think I could do it if necessary, following the instructions posted here, I much prefer to spend that time and effort on shooting instead....:rolleyes:

 

I only got into the shims when trying new

‘’ground-glass’ in the body: a total waste of time as the real glass original is just

fine!

 

On that issue, I just couldn´t agree more! Whatever people say about new bright screens, there is, and always will be, a tradeoff between brightness and ease of focus - and the Viso screen is already right on my personal sweet spot in this respect.

 

And, for closeup or for real long, slowish lenses, nothing beats a plain screen without any split image or microprism fields smack in the middle.

 

So the original screen stays right where it is! :)

"In order to be able to focus to infinity, all you need is the M9, Visoflex III, Universal Focus Mount OTZFO = 16464 K, and the TE 135/4 lens head."

 

What's the difference between the TE 135/4 lens and the TE 135/4 lens head?

Do you have to take the lens apart to use it with the 16464/Viso III?

Excellent question!

 

Some of the older lenses, both M-bayonet and Telyts were designed in such a way that the lens head can be simply unscrewed. That way the lens heads can be attached to a shorter focusing mount or a Bellows II ( for macros) and used with the mirror box, called Visoflex I, II, or III.

 

These lens heads or complete Telyts as well can then also be used on DSLR cameras, such as Canons, Nikons, etc. with an appropriate adapter of course.

 

Available focal lengths cover 65, 90, 125, 135, 200, 280, 400, 560, and I believe 800 mm.

Used in this fashion the lenses focus all the way to infinity.

 

Best, K-H.

KH,

 

Thanks

 

Presumably, if the TE 135 does not unscrew easily, one shouldn't try harder.

 

In other words, do later models come apart for use on the viso, or is this adaptability a feature that Leica eventually dropped in later model lenses?

Mine (depicted in post #18 in this thread) does indeed come apart. If you look at that image, the division is right behind the knurled aperture ring. Grasp the aperture ring with one hand, and the lens barrel in front of the focussing ring with the other, and turn the front counterclockwise. Some force is indeed needed, but not excessively so.

 

The optical head that you´ll get exposed is far longer than the part you see at the start, but that´s as it should be. There are two sets of threads on it; the front (larger) one is what mounts it in the lens barrel, while the narrower one close to the rear end is the one that mounts to the universal focusing mount that is used on the Visoflex.

 

Don´t know if the newer model with built-in lens hood (Ken Rockwell has images of the two) does come apart; doesn´t look so...

 

BTW, there´s a nice review of this lens on Steve Huff´s site.

I’m in the middle of a too tightly threaded part just now. It’s time for the old hose clamp

trick. Wrap the part with a rubber strip and use multiple short hose clamps to surround

the rubber. Tighten very well and use big water pump pliers to grip on the raised screw

sections of the multiply clamps. WD 40 overnight helps a lot.

While an excellent method for real jams, it sounds a bit drastic for this situation. Remember, you´re working on the aperture ring turned to f/4, where it´s stopped by a rather small pin that takes all the force. And even a liberal amount of WD 40 won´t reach the stuck threads rather far down inside the barrel.. But then, if someone *tightened* it using a similar method....;)

 

When adequately tightened so it won´t come loose with everyday handling, the feel and force to unscrew it is about similar to opening the screw lid of a big Coke bottle first time... The value of the contents released, however, is very different....:D

I just removed the ring…. no fuss, no muss, no problem. Do you know how many times

I’ve done this? (and, never a problem other that getting the part off)

Oops... see now my post was a bit unclear (must have applied a liberal amount of whisky last night...:p). Rip, in no way did I feel any need to ´teach´ or correct you personally about this kind of work; your posts about complicated mechanical projects you´ve succesfully undertaken speak for themselves....

 

Only, I felt that if some other reader came across this thread and tried to apply the method to a stuck TE lens head, they might benefit from a warning that there are weak points. That was my only reason for writing that post last night.

 

And... it really hurts seeing your Novoflex gear; each time I want to kick my own arrears for selling mine.... only, with my beer barrel belly, it would be quite a long walk around to get into position for that....:D

Per,

Heck no buddy I didn’t take it that way at all. I just was really just providing a photo of

the set up to make it clear what I mean. All doubts are helpful because one thinks

over the situation and may find a better way or a flaw in my solution. I welcome doubt!!

Actually you are quite correct to point out the bottle-cap problem where-by ring

compression adds to the tightness…. you also are REALLY right about not using the little

limit pins in aperture rings for turning force: you sure will break the pin!

I have been successful with this method but there were times where it didn’t unscrew

at first try… and times when I had to wait awhile and try alternatives… I am very

careful NOT to be a cave-man and try to force it after a certain point. Usually more penetrating oil

left for a long time and reapplied to creep into the assembly. On tough ones I sometimes

have to use two of these clamps…. one on the male&female part so the torque isn’t taken

up by a too delicate part on the assembly. Cheers.
