The letter 'K' in the lens name indicates that the HELIOS-44K-4 58MM 1: 2 is using bayonet 'K' (Pentax K). Helios-44-4 bayonet lenses are not common. The original HELIOS-44K-4 58mm 1: 2 was used on Soviet Zenith cameras with a K mount. Nowadays HELIOS-44K-4 58mm 1: 2 is interesting for owners of Pentax DSLR cameras, as the lens mount is mechanically compatible with them.
