Question about a Pentax M lens

commissioneranthony · 07-30-2011, 10:31 PM

My father let me use his K1000 and lenses for photography because he gave up film (shame, shame) but I happened to come across a lens designed for the pentax K mount which I cannot find any info online about.
Apparently, he purchased the lens at a "fortuneoff" for $99. Yes, I have the receipt. He's one of those.
Anyway, the lens is a 85-210mm Fortron Auto Zoom" f4.5 lens (not auto at all btw, and I dont mind)
Surprisingly enough, this lens is incredibly sharp and easy to focus (well on a tripod or against a tree

)
I have a 70-250mm sakar lens for canon FD which wont truly focus for the life of me and is incredibly dull, yet there is no signs of dust or fungus or scratches/aberrations on the lens.

I just want to know who really made the Fortron lens. I think it probably was Ricoh, as the only thing that comes up from a "fortron" search is a Ricoh lens on ebay. The lens design also wasnt a dust pumper either, but rather a 2 stage lens with aperture dial, focal length adjustment dial and fine focus dial.

Anyone owned a Fortron lens? Thanks a bunch.

Sounds interesting. Can you post pictures?

The lens is all metal construction, even the hood is metal. Feels like the build quality of a SMC pentax lens. A world of difference when compared to a canon FD lens. Cant stand plastic the construction of those FD's.
If you want some pictures taken with the lens I can post those too, but there is a awful lot of wobble when using this lens. I need to get a lens mount for the tripod. Using my GF1 + pentax k adapter on a tripod still wobbles all over the place

Here's some pictures of the lens:

That looks like a near-twin to my Gefitec 85-210/4.5 serial #352147 that I've attributed to Kiron. Mine is Minolta-MD mount so I can't use it (and I'll sell it cheap). But Kiron's fixed-max-aperture zooms have a decent reputation; this one would be rather slow but nicely sharp. And yeah, it is SOLID! Mine weighs 650g. I think you have a budget beauty there!

^^Thanks. The lens is built like a tank, and weighs like one too

It is really useful for up close shots for school concerts and the such
(on micro 4/3 it is 2x the field of view, so that's why)
