Cool. Let us know how it is done when you achieve a favourable conclusion.

Not generally. I have noted the Takumar's to be quite resilient to this issue.
OK I think you have diagnosed the problem. It sounds as though the helicoid is not set to infinity correctly. Easy adjustment, but requires the right tools and a camera. Definitely discuss with seller.

That part of the lens has nothing to do with the focus mechanism. Being loose tells me the three retainer screws are not as tight as they ought to be. It also suggests the lens has been dismantled, providing further evidence that the focus mechanism may have been tampered with and/or incorrectly set. Hmmm perhaps the lens needs to be looked t more closely.

Nice shots. You should be happy with those. When you shoot this lens, remember, the sharpness is best found stopped down. But wide open you get better critical focus. So working the aperture ring to your favour is a must for this lens.
If you shoot wide open you will need to do a little PPing to boost contrast. that will boost apparent sharpness.

Yes way too short. Something does not seem right to me. I have a similar adapter and lens and have used it on my dad's Sony a7r without problem. So I suspect your lens or adapter or both are to blame. We would be very keen to hear of your findings with the m42-k adapter on the ricoh.

Yes, the adapter is too short.

Oh you want to send the lens back. Hmmm. Yeah, wait for the M42 - K adapter and check then. Good idea.

You can change the focus relatively easily. You will need to break open the lens from the front element. Not hard, but you will need a spanner wrench and a little patience.

It looks like the right adapter. NEX = E Mount I think (someone with more knowledge should confirm this).
If the lens is reaching infinity focus at 2 m then one of two possibilities:
1) The adapter is horribly wrong and/or
2) The lens is not tuned correctly.
The latter is unlikely but possible. Do you have a spotmatic to check the lens focus accuracy?
