Tefnon macro 35-80mm 3.5-4.8

Hi all,

In my Box of Assorted Junk there's a Tefnon 35-80 that came with a P30 (I think). It's a 35-80 zoom lens with automatic mode. From Google I've found tefnon was brand used by a manufacturer called Kobiri but not much more. Does this name ring a bell with anyone? Any additional info?

I Have a Vivitar 70-210 4.5 zoom lens that was made by Kobori. My copy is for Canon FD mount so I don't have any digital files taken with this lens. Try it a post your results.

I can post some test shots tomorrow. Quick question - on the K5ii, when I start up with an older lens, I'm asked to input the focal length. This is simple for pirmes, but what do I put in for a zoom? And what does this affect?
