What is pentax pk

Without going into details, could you roughly describe the steps to remove this piece of metal? Thanks, armel. Posts: 22, Where Pentax created the "KA" mount in order to support Program and Tv exposure automation, Ricoh had to create their own variant, which has a protruding pin placed in a somewhat unfortunate location, namely in the exact spot where Pentax years later placed the autofocus drive shaft.

Such a Ricoh lens will get stuck when mounted on a Pentax autofocus body - the Ricoh pin will get lodged in the drive shaft and prevent the lens from being removed without deployment of finesse, patience and tools. The other trap is the shield that protects the aperture stop down lever. The image to the left shows what the shield should look like and does look like on a genuine Pentax lens.

Some older third party lenses have a much larger shield which prevents mounting the lens on a Pentax DSLR. Current third party lenses Sigma, Tamron, Rokinon, etc. See Flange fix for Vivitar lenses.
