Anyone familiar with Tefnon (Kobori) brand lenses?

I succumbed to buying yet more lenses at auction and came up with this zoom, TEFNON H/D-MC 75-205mm F3.8-4.8 MACRO. Pentax K-A mount (no Ricoh pin)
I was only able to find few references (sales) of this lens on the WWW but the Pentax lens reviews does have a SOLIGOR C/D 75-205mm F3.8-4.8 MC ZOOM-MACRO that looks identical. I could find no links between the two or Soligor using Kobori made lenses.
I was pleasantly surprised with how sharp this lens is, If it is the same lens as the Soligor I can review it there.
Some images, the lens and an image taken at the wide end and a crop of it, note the Ant.


Anybody with some experience with this (or any Tefnon lenses), please offer some opinions.

I have no experience with those lenses, but I remembered seeing this on MFLenses.com:

Soligor 9 Thy name shall any more be called Kiron but Kobori

Thank you for the link, it appears that this Tefnon and the Soligor have been identified by someone as the same lens.

You're welcome.

I also enjoy learning more about my new /old lenses. Navigating the maze of manufacturers and models is part of the fun of photography!

Well I am learning a lot from the forum and for $15 this is a surprising lens and works rather nicely.

I used Vivitar 77xxx serial #s which are Kobori as best I can tell. I really liked their 28-105mm lens, decently sharp and great color. I had another #77xxx but forgot which

Finally found my favorite 28-105 image. I knew it was online somewhere, found in my Picasa archive

Cropped and shrunk, can't recall any processing but I might have toyed with sharpness?
