No idea then. I would wager that there are more Pentax M42 and K mount available than ALPA, Contarex or Contax lenses combined, so you would think there is a reasonable business case to make a Pentax adapter.

Dumb M42 to EF adapter works fine on the Speed Booster.

not necessarily:

Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster™ and cause damage to the Speed Booster™ and/or camera body.

An why buy 600$ EF->NEX adapter, if you haven't EF lenses, just manual m42?
