Maybe I'll Try Tilt-Shift...

I have not run across any tilt/shift in M42.

I use a Mirex Mamiya 645 to EOS Tilt shift adapter on my Sony A7r( via an EOS-nex adapter) somewhere here is a thread with my experience. I like it alot...but it is expensive( the Mirex was made to suit the A7r even though its EOS mount). The cost is in the engineering....it works brilliantly and simply! The cost all up of two mamiya medium format lenses( one a macro) and the adapter was the equivalent of the canon 24mm tilt shift. Bellows may be the way to go contax made a very nice tilt shift bellows( I have seen one recently with an M42 mount) Hama also produced a multi mount Bellows that looks like a miniature view camera......BUT! There is always a But! I have a Minolta Tilt shift bellows. I only get about 5mm of shift, to be honest it just isn't worth(cost wise) it for such a small movement. with the mirex I get a maximum of 15 mm shift , although 10 is the maximum I use on my full frame camera.

Edit: to get the full benefit of Tilt shift you do need to use a lens that projects an image circle much larger than your ameras sensor. As a general principle for an APSc sensor you need to use a full frame lens. For a full frame sensor you need to go for medium format lenses.

My adapter is , as you say EOS on the camera side. Lens side is mamiya 645. The adapter costs US$500.00 approx. Performance with Mamiya sekor C 35mm n lens is better than the canon 24mm tilt shift. Its not suitable for adapting to M42. Any Tilt shift adapter is going to cost. I don't use tilt for macro...Shift I have found the most useful. you might want to try just a shift adapter. Your enlarger lens sounds perfect

kippon makes one

OK then you may have to assemble your own adapter. M42-what ever mount you can find a decent shift or tilt shift adapter in. You might be able to print what you need better but heres how to assemble an odd ball adapter: first buy a cheap step down filter ring ( 52mm -42mm)Usually the cheaper ones are the ones that have what you want( a female thread all the way through) You can then screw your M42 lens into one half of the step down filter ring:

Heres an example of one on ebay:

Then you get a reversing ring M42- to the mount of your tilt shift adapter:

that reversing ring screws into the other half of the step down ring.

The problem is is finding that reversing ring. However I think you get the idea. If you cant get an M42 to "your mount" reversing ring then reverse the buying process find what reversing ring is easiest to get. then get a cheap step down/set up filter ring that will enable you to connect the M42 lens to the reversing ring.

Unless the bellows is the Hama Mini view camera type( allows for swing as well as tilt and shift) or the Mamiya Medium format bellows I really doubt one could even get an image on the camera sensor by shifting the bellows as it mounts to the camera.

Heres how the tilt shift adapter I use works with a Mamiya 80mm macr0. The coin is in the lenses peripheral vision( so to speak) yet is centered on the sensor. The coin is not quite out from under the lens but it makes for a different lighting approach. I plan to replace the 80 mm lense with the 120mm. the extra distance should see any coin completely out from under the lens:



Note that shot must have been an early one because there is a full 15mm of shift being used.

Heres the sort of result( this coin is diabolical to photograph!!) its silver dollar sized I used only 10 degrees of shift there was no editing other to put reverse and obverse in the same file




I have had people recommend tilt to me but when I have questioned further I found that no one had actually used tilt. My experience with tilt has been disappointing
