I borrowed a photo from Ebay... All rights to the owner who is shown.
The seller says this design will allow for infinity focus. ???. I know the mount distance of the M42 and K are the same: A perfect adapter of a flange design would require a thickness of zero. Is there anything different with this one? Is there an offset that the others do not have? Is that even possible?
The last two adapters I had were both third-party, one aluminum similar to this and one internal with the removal tool. The internal was hard to remove. I do not recall that the aluminum adapter did not reach infinity, though I may have unwittingly not shot anything more than about 50m with that lens. ???. Maybe I got lucky.
I was ready to get the OEM adapter, but saw this ad and was curious.
