How do I fit a Leitz Telyt to my K20D

My 200mm f/4 Leica Telyt has a (39mm ?) thread at one end - my problem is how to fit it to a Pentax bayonet camera and get manual infinity focus. This lens is not featured on the "Leitax" web site, so I am unsure which spacers or adapters will do the job.

(The Telyt has the number 11063P on the box, and "Leitz Canada 1851510" on the lens - if that will accurately identify it)

If it's a visoflex, then visoflex to Pentax 67 or 645 adapter then 67/645 to Pentax K adapter.

Or this, which requires an original visoflex to Leica bayonet adapter: Visoflex 14127

Pentax also used to have an M39 thread on its screw mount lenses before moving to the M42 mount. They did make and sell an adapter for M39 to M42 mount.

I'd Google it and search eBay for such a device.

I use that exact lens on both a Pentax and a Nikon, by monkeying around with adapters.
The main problem is that you need a good bit of extension to make up for the missing Visoflex.
I've also found that having a bunch of thin shims is handy, mainly because after you thread all those adapters and extensions together, the markings aren't on top where you can see them.

I have the most fun with that lens mounted on the old Visoflex bellows (the lens head unscrews from the regular focus mount) - even then I use a bit of extension on the rear end to achieve infinity focus without having to waste bellows draw.

Make no mistake, it is a really, really good lens, that will embarrass most tele zooms - even the pricey ones.

If you scroll down to February 2013, you can find what I wrote about it here...

Ummm....Actually the AsahiFlex cameras used a 37mm screw mount. I'm sure that if there had been a 37mm to 42mm adapter my Father, who's AsahiFlex I now have, would have bought one. Such an adapter would probably have increased the flange to film distance enough to make infinity focus impossible. You may be thinking of the M42 to K-Mount adapter, which works very well. No auto diaphragm, etc, however.

Visoflex has a much longer FFD than standard m39, so the problem with this lens would be the opposite.

For what it is worth, there are 39mm to 42mm adapter rings, usually very cheap on ebay.
They are used for adapting some old Soviet lenses to Pentax and others via a 42mm to bayonet adapter ring.

I'd go with what dcshooter says above, however. I don't think that 39 - 42mm ring is what you need here. But it does exist.

For the benefit of any other members who might want to use this lens, obtainable sometimes at a reasonable cost on flea-Bay, here seems to be the best solution ---

1) My Telyt 200 has a Leica screw thread because it was intended to be used on the Visoflex I, which is the thickest of the three Visoflex units made.

2) So I first convert it to Visoflex II/III (thinner than V. I), by using an OUBIO/16466 spacer.

3) Then that combination fits on to a 14167 to convert to Leica-R.

4) Then I convert the 14167 to Pentax by exchanging the final bayonet for a Leitax adapter, one specifically made for the 14167.

I am currently assembling the necessary parts and will report back with results when complete.

One question then - what other Leitz lenses were made for the Viso. I, which will therefore have a screw fitting ?

Dan.

Nice adaptation! I have the same Telyt, which I used with Viso III on film Leica, and also on M9 for digital, but the Viso is still clumsy in that setup. The Viso works much better for macro use on an M9, where I use a 65 Elmar.
I use the 200 now with an R adapter to A7 adapter with a Sony A7. Works very well. I've been meaning to shoot a comparison with the Telyt, Super Tak, and Canon FL 200s, all on the A7.

And one minor advantage of using an OUBIO/16466M is it has a built-in tripod socket, and rotatable center section.
