I was playing around with a Leitz Telyt 560mm f/5.6 that a friend of mine wants me to sell:

at f/5.6


at f/6.8


It is a large lens, but relatively lightweight with its two element design. The Televit R focussing system is a little different from the Novoflex PiGriff I am used to, but it works very well when used on a tripod. I remember reading a long time ago that people preferred the later f/6.8 version of the lens, but this f/5.6 looks pretty good to me. The f/6.8 is smaller and more lightweight though. A comparison of the two lenses, both shot at f/6.8 on my Sony A7.

Nice.
I have actually just acquired a novoflex 600mm f8 optical/iris unit to try out on my pigriff.

Am I right in thinking that the 560mm can go on a pigriff?

There are certain 560 Telyt heads that fit certain PiGriffe. The Telyt 560/5.6 doesn't fit onto any Novoflex PiGriffe, at least not by design - anything can be made to fit obviously. The aperture in the Novoflex aperture housing is too small a diameter for the 560/5.6. The Telyt 560/6.8 comes in 2 main versions, one for Leica R only, with a sliding tube focus system, the other for Novoflex PiGriff. AFAIK they were only made for PiGriff C and D, these two have the same breechlock bayonet mount, PiGriff A and B (with a focussing bellows rather than a focus tube) have a different one.

That being said, there are parts that are interchangeable. All 560/6.8 lenses I have seen are the same optical part, the two element lens can be screwed out of a Leica R sliding version and screwed into a tube connecting it to the Novoflex aperture housing and vice versa. The Novoflex 560/6.8 comes in at least two versions of tubes, one is a single tube where tube and aperture housing are a single piece or glued together, the other consists of separate tubes and aperture housing that can be unscrewed.

Thanks for that useful info dickb. So from what you say the connection of at least the 560/6.8 is a pigriff compatible bayonet. That would suit both my "B" and "C" pigriffs (only the 1st gen "A"s are a screw connection).
I wrote the novoflex description on PF:

This pic by Horst Neuhaus illustrates the modular parts of a "B" system.



However the "B" 600mm I havehas more sections than shown.

Well, almost. There is no Pigriff compatible bayonet, there is a Pigriff B bayonet and a Pigriff C/D bayonet. The B version has a much smaller diameter. I measure 47mm. It has a male bayonet on the rear of the PiFas or aperture housing, the C/D has a larger, roughly 73mm diameter, female bayonet on the aperture housing. All the Novoflex Leitz Telyt 560/6.8s I have seen come with the PiGriff C/D bayonet.

This doesn't mean it is impossible to mount it onto a PiFas B though, the front thread of the PiFas B is what I quickly measure to be 77*0.75, the same as the front thread of the PiFas C. So any lens that fits onto one aperture housing should fit onto the other.

I just realised the PiFas B conical rear end unscrews from the aperture housing, revealing a 70*0.75 thread.

I just made a similar image of some of my lenses, from top to bottom
PiFas B with Noflexar 400/5.6 (2 element lens),
T-Noflexar 400/5.6 (3 element lens),
PiGriff C with PiFas C, some tubes I don't know the correct code for, Noflexar 600/8,
PiGriff D with PiFas C (maybe D, I don't know if there is any difference), again a tube and the Leitz Telyt 560/6.8 :

I left the lens hoods out, they are all the same for the Novoflex lenses, the Leitz has a sliding lens hood.

And since this thread started with the 560/5.6, also a picture of the Leitz Televit R system with 560/5.6 and 400/5.6:

And a quick shot with the 560/5.6 out of my office window, onto the flat roof where oystercatchers raise their young:

Nice.
I'll try and post a pic or two with the 600mm f8, when I've cleaned the optic and the sun comes out....

And thanks for the good info, i have amended the descriptions on PF.

I just did a quick test of a fairly boring wall, with the following lenses:

- Leitz Televit R with Telyt 400/5.6
- Leitz Televit R with Telyt 560/5.6
- Novoflex Pigriff D with Telyt 560/6.8
- Novoflex Pigriff D with T-Noflexar 400/5.6
- Novoflex Pigriff D with Noflexar 600/8.0

If there is interest I can post some of those, but looking at them on my monitor my conclusions are (bear in mind, these are all just one copy of old used lenses, YMMV):

All Leitz lenses are already very good wide open, the Noflexars improve a lot by stopping down at least one stop, especially the 600 is rather poor at f/8
The 560 Telyts are just about at equal at the same apertures, and the f/5.6 variant is already very good at f/5.6 - this surprised me a bit as I remember reading the f/6.8 being clearly superior to the older f/5.6.

Some more examples taken with the 560/5.6 and my Sony A7, the first two show off the beautiful round many bladed aperture

#1 at f/5.6


#2 at f/8


#3 at f/5.6, some vignetting, possibly caused by my Metabones EF/E adapter


#4 not sure which aperture
