komuranon s 75mm 5.6 enlarger lens

[jamaeolus]

Picked it up for 35 usd. Planning to use it for macro. The threads are 39mm (I think). Would LSM adapter work? Going to canon ef. I have extension tubes and bellows. I was thinking LSM to m42 and bellows or helical. Thoughts?

Should work, I have a Kominar-E 75/3.5 that hits infinity near it's focal length distance from the sensor on my E mount bellows, I don't think you'll get that far, I would guess 3 feet(0.6m) and closer.
M39 to M42 step ring(vs LTM to M42) on an M42 bellows with M42 to EF adapter should work, My only worry with thread mounts is the bellows not being aligned correctly with the camera.
M42 helicoid should work too, with extension rings to get your magnification close to where you want.
Some ideas:
