Saw this amusing little number on eBay. It is without a doubt the oddest ployglot of a lens that I have ever seen. Lens barrel appears to be from a Pentax K-mount lens, the optical block is from a 1953 Carl Zeiss rigid tessar, while the fixture holding the optical block is from a 1945/1946 CZJ collapsible lens nick-named the "black-line tessar". Also, it looks like the lens mount on the camera has been modified, perhaps a spacer has been added to the rear of the lens or the camera mount to get proper registration Not interested in purchasing, but I have to wonder if this setup even focuses properly. Very unusual to hack a rangefinder lens onto an SLR.

The Tessar has a large distance between rear element and plane of focus- it should work. Note the lens and body are both modified.

Love that Linhof badge attached to the front of the Pentax body.

Yeah, the Linhof tag was pretty funny.

What's more is that the Tessar is a mix of a post-war Carl Zeiss Oberkochen rigid Tessar lens and the body of a collapsible post-war Jena Contax mount Tessar.
Yet it retains the aperture of the Oberkochen lens. What in the world?
The focus mount and/or lens body is from a Pen F (half frame SLR) 25/4 lens.

I assumed that the lens barrel was from a Pentax K, thanks for identifying it as from a Pen F. This makes the lens even more weird. Literally built outta spare parts.
I've converted Exakta Mount CZJ 5cm F3.5 Tessars to Contax mount, and shimmed one for S-Mount- using left over parts from converting 5cm F1.5 Sonnars. The Tessars in Exakta mount are cheap, usually under $50 when I was getting them, as low as $10 several years ago. I picked up a beautiful 5cm F2.8 Tessar "T" for ~$50 a couple of years ago- could not part it out. SO- now have an Exakta to Z adapter. Tessars work well on SLR's. This must have been built from spare parts. The MX is an interesting choice.
