Petri only made one lens mount, but they also used M42 mounts.  Some Petri lenses have Pentax K mounts but they were made by third party manufacturers such as Cosina.   Petri bayonet and M42 mount lenses were excellent.   The Cosina made lenses are not the same build quality but the optics can be quite good.

The Sigma mount has two variations.  The first version has two bayonets to support heavy lenses.   That feature was not actually used so they removed the extra bayonet with the introduction of the SD14.  All Sigma AF bodies use the Sigma bayonet mount.  Early Sigma MF bodies used Pentax mounts.

The Edixa m42 mount is oriented slightly off of the Praktica standard.  Lenses with aperture arms and automatic aperture lenses made by other mfg's will not work properly on an Edixa body.  Also, Edixa lenses may not work properly on standard m42 bodies.

Vivitar TX mounts look very similar to T4 mounts but they are not fully interchangeable.   T4 mounts can be used on TX lenses but TX mounts can not be used on T4 lenses.   TX mounts have slightly better automation.  

T-Mounts thread onto telescopes, mirror lenses and preset lenses.  They do not offer any automation.   T2 mounts are adjustable T-Mounts.

Tamron Adaptall

Tamron Adaptamatic mounts attach to the lens a bit awkwardly and are tightened to the lens by way of a large retaining ring.   Adaptamatic mounts offer limited automation and can be tricky to attach.   Tamron replaced the Adaptamatic with the Adaptall system which offers more control and is much easier to attach.  

sigma YS lens mount

Sigma YS

reg - 55mm

Sigma YS mounts are basically T-mounts with an aperture pin.   They are adjustable and must be adjusted to achieve proper alignment of the aperture pin.

NOTE: Don't mistake T-mounts, T2 mounts and YS mounts for M42 mounts.   They are all 42mm but M42 has a different thread pitch.  They are never compatible with each other.

Komura used two interchangeable mount systems.   The first was a 47mm threaded adapter similar to a T-mount.  It is called a Unidapt.   Do not confuse this with a rare Tokina adapter which is also 47mm.  The second system is called Uni Auto.  It is a bayonet system similar to Tamron Adaptall.   Both adapters can be very hard to find.  This pic was borrowed from a forum.

Tokina lense, made in the 1960's, used an interchangeable mount similar to a T-mount.  The mount was 47mm threaded.  Don't confuse it with a Komura 47mm mount.  These lenses and mounts are rare.  These are also called Hanimex H mounts.
