I have two vintage Albinar lenses from a yard sale and want to adapt them to my Sony A5000 (Sony E-mount). The mounts have three bayonet tabs and two linkages/pins. The lenses are:
- Super Albinar MC Auto Zoom 38-70mm f/3.5
- Super Albinar Auto 100-200mm f/5.6
Can anyone identify the mount and tell me what type of adapter I need for Sony E-mount?

Your lenses appear to have Pentax K mount. They should work with adapter without any issue. However, image quality is unlikely to be comparable with modern kit lenses.
The Pentax K mount is a bayonet mount with three tabs. There is an aperture control pin that opens and closes the aperture. Opposite that, there is a coupling pin that communicates the aperture setting for metering wide open.
There are multiple variants. When used with adapters, the differences among them is inconsequential. One variant has a "Ricoh pin" that can get stuck on the autofocus screw drive of Pentax bodies. It is not an issue with adapters. Also, newer lenses may have electronically controlled aperture and focus that are unusable with adapters.

These lenses appear to use the Pentax K mount.
Pentax K is a 3-tab bayonet mount, and the extra parts you see are consistent with its mechanical aperture linkage/pins. There are several K-mount variants, but for simple mirrorless adapting, those differences usually do not matter.
For your Sony A5000, you’d want a Pentax K to Sony E-mount adapter.
A couple of notes:
- Some K-mount lenses include a Ricoh pin, which can cause issues on certain Pentax bodies, but that is generally not a problem with a basic Sony E adapter.
- Very old third-party zooms like these often won’t match the image quality of modern kit lenses, but they can still be fun to experiment with.
