ORTUX correction lens for Leica I-IIIa

Good morning!

 

In the 1954 Leitz Katalog (German version), p. 25, they show a screw-in type correction lens ORTUX for models I-IIIa (for rangefinder eyepiece as well as viewfinder eyepiece), the then order number besides the codeword was 4031. I'm looking for a +1.5 or +2 model. This item seems to be extremely rare. Can anybody give me a hint about an offer?

(And, btw, I'm also looking for an orange contrast filter ORAKO, 10mm diameter for II, III, IIIa - not the OKARO model, 11mm, which is for IIIb-f).

In case of being successful I'll of course contribute the adequate fee towards the buy and sell section. (Placing a "want ad" there is not really promising I'm afraid).

 

Thank you

...I think it's probably easier to have it hand made by an optician... :o

 

Thanks for the first quick response.

Finding/making a frame and threading it properly seems to be the bigger problem then, compared to making the small lens. Think of opticians' time rates.;)

You must find an optician who is also a Leica passionate... ;) he/she will UNDERSTAND... and if you promise him/her good review on the forum... and if he/she is business-oriented... "let's make a deal"...:)

I live in the northern most part of Germany where the "Leica-enthusiast-density" is already pretty low, but trying to find the combination Leica enthusiast plus optician seems to be useless..... .

I did discuss this at length with my optician, who is very understanding about these things. The problem comes in coping with astigmatism (which I have in abundance). The mount for the lens would need to turn through 90 degrees for the occasional vertical shot!

 

We 'solved' the problem by having frames for my glasses with lenses which are just small enough to get in under the ridge of bone above my eyes, so if I really want to see all the 35 mm frame on an M2 I can push the specatacle lens back from its normal position into my eyesocket with the camera viewfinder. With the modern trend for narrow slit like lenses this wouyld anyway not be a problem!

Not so much a problem with the M6 (0.72) since they reduced (and made less accurate) the size of the 35 frame, the 28 is hopeless though!

This is one of the reasons why I chose the M3 back in '68, less of a problem with that as the 50 frame seems further from the edge of the viewfinder.

Thanks for your "eye-witness"(;)) report. With M I do not have problems as there are lenses produced and available, but with LTMs it is really a problem. Fortunately I don't suffer from astigmatism, it is farsightedness due to my age only.

Yes, with my III I don't bother with the normal viewfinder, I use one of the many and various external viewfinders I have accumulated over the years!

The rangefinder has enough adjustment to cope with my eyesight.
