It has a 60mm screw mount.
This lens was made in a series over 10 million and I can't find one 60mm to bayonet adapter anywhere.

It was my granddads so I'm really eager to make it work with AF100

What lens mount is that? I looked here: http://en.wikipedia.org/wiki/Lens_mount#List_of_lens_mount_types
And I can't find my 60mm screw type mounts, so it must be a really old mount not on the list.

What about using a step down ring to a size that's a little more common? Then you could probably find the adapter on Ebay (search on Ebay 'Micro four thirds adapter' there is a ton). But then the problem is getting the correct distance to the sensor.
 
The big issue is that you're going to need to mount this 200mm or so from the image plane, and provide a mechanism for moving it in and out to focus, which was the function of the bellows in the original view camera.

The easiest way might be to take an existing telephoto lens of some kind (with M43 or at least some type of mount easily adaptable to M43) and disassemble it, removing all the actual optical elements but retaining the outer shell and focusing mechanism. I suspect you'd need a machine shop to make a threaded ring to hold the Tessar that could also thread or otherwise lock into the shell of the "donor" lens at the appropriate location.

Around here, the average pawn shop would probably have several good candidates for an old, cheap lens you could cannibalize for this purpose.

You might also be able to modify something like this fairly easily:

Thinking of fitting it to a M42 to canon EF adapter via a home made wood cylinder adapter. then from the EF to a EF bellow connected to the speed booster, connected to the camera.
That's going to be a monster.

What do you think of that?

Another note, that lens is made for a image plane (sensor size) of 13x18cm, think if the short DoF that would bring :)
That square in the middle is full frame.

Maybe find or have machined an adapter from the lens thread to pentax screw mount, then mount on a pentax macro bellows, then a pentax to mtf mount on the rear. SK Grimes might be able to make that adapter if not a standard thread.
 
Here are ideas for the pieces that you could use to build a mount.

1: A M/43 to Nikon Adapter.

2: A Nikon Bellows. Could not find a bellows for the M4/3 mount but there might be one out there somewhere.

3: A 60mm adapter ring for the thread mount.

If you don't have machining capabilities you could epoxy the 60mm ring mount to the front of the bellows.


If the bellows is not long enough adding a few Nikon extension tube would help. I have a Sony F3 and I have built lens mounts for lots of different lens brands using adapters as a starting point.

Here are 2 more 60mm lens mounts that have better clearance for your lens.
