Sigma Mini Wide: interchangeable mounts

[Pancolart]

This might be helpful to someone. Mounts on Sigma Mini Wide lenses can be switched. Each lens is made to support different mounts. Aperture ring has different scales to be shown in transparent window, even orientations. At least for 4 different mounts. Quite a genius of Japan economical engineering. My switch was from Contax/Yashica to Olympus OM which i needed mint to supplement SLR camera. Perhaps this is valid for other focal lengths too (i cannot verify).

Any pictures?

Seems like an interesting idea, I think other lenses have been talked about before supporting something like this.

Do Sigma Mini-Wide II mounts fit Sigma Mini-Wide I lenses?

Three different systems but the ring at the bottom attached with screws is specific to Pentax (From the Sigma 28-50mm 1:2.8-3.5) There are three aperture scales on the ring. The one used lines up with the corresponding scale below (on the other side here because it is Pentax)

To complement D1n0's photo, this is internal situation where there are 4 different aperture slides. Aperture ring can be turned around 360 degrees to match the selection. Mounts fit accordingly. The calculation for this was high level. Don't know if Mini Wide II version still sponsors such option.
