Sigma 28-70mm f2.8 MF PKA mount

[ducdao]

Hi all - can anyone let me know anything about this lens? I searched the internet and can't find anything on it. Does it have the same optics as the AF series?

I just got it and took few test shots and so far I like it but would love to have more information on it. Can anyone shed some lights?

Note this is the Pentax PKA mount.

No one has heard of this lens? It looks like it's a very rare lens. I can't find any information on it. Maybe I should try contacting Sigma. I'll report back if I have any news.

could it be that it is optically the same as the later AF lens?
at least here, the first reviewer seen is talking about his manual focus lens, others it seems mostly about their AF lens:

I do have this lens into C/Y Mount - way good condition, i'd say 9/10, or 9.5/10....but just since today, so no samples yet being made with.
