Re: Screw grip and PHV1

Quote:
In double gun nomenclature, a "screw grip" is a fastener that operates on the interrupted thread principle and is activated by a lever. Sorta like a bayonet mount camera lens, a partial turn of the lever fastens, and a partial turn in the opposite direction unfastens
Actually, a bayonet camera lens mount is not in any way like a screw grip fastener.
A bayonet lens mount does not use an interrupted thread system for its attachment to the camera body.
A bayonet mount and an interrupted thread are completely different systems.
