Sigma UC Zoom 70-210mm 1:4-5.6 I hope all 3 pics have uploaded correctly &, if so can anyone identify this lens mount? as this lens doesn’t fit any of my cameras.
Probably not Pentax (I’m a long-time pentaxist and I looked at my lenses). You should look at the text on the lens. Generally, the reference of the lens indicates its type. One of my lenses in not from Pentax, but it’s marked “-Pk” at the end of its marking, which means “Pentax K mount “.
It’s a C/Y (Contax/Yashica) mount.
Does anyone have pictures of this lens being broken down? I forgot where everthing goes
