Adapter combination Pentax K mount lens to BAL-F bellows
-High-precision adapters
-no information transfer between lens and the bellows unit
NOTE:
It is a combination of 2 adapters - the rear one has the bellows connector, the front on is lens-specific and can be exchanged for an adapter for another lens.
Both adapters are connected via the M39 thread, so M-39 lenses can also be used after unscrewing the front adapter
