Originally posted by stevebrot Yes, this lens dates to the late 70s or 1980s, but no, it is not related to any of the Vivitar lenses. Kalt was (and still is) a re-brander of inexpensive photo accessories. At one point, they also dabbled in cheap lenses. Your 28/2.8 is one of a score of generic lenses that were common at the time and would have been equivalent to a Focal or Hanimex. Yours probably was not bad when new, but your photos indicate a lens in distress.

...or get a Vivitar* or
XR Rikenon of the same vintage for about $30 USD. For some reason, the prices on Pentax-M 28/2.8 lenses has skyrocketed. I can't imagine why since the lens was actually priced (about $35 IIRC) below that of a Vivitar (about $45) when new and is not a standout in any way other than the SMC coating.

* I have a Komine-made Vivitar 28/2.8 and it is a very fine lens.
Yeah, I'm starting to wonder if anything I learn from this lens is going to be "wrong". I have to stop the thing down so far to get a clear picture out of it that even with the ISO at 800 and in a decently lit room, I have to run a long exposure time to get enough light in to do anything.
I just ran some back to back shots here at my desk of a speaker. First up was the Kalt and it's sort of... you've seen what it does. Back to back against the 18-55mm kit lens that came with my old K100D, I think I like the kit results better. I don't think this is a fungus issue, I think this lens is damaged from sitting at the bottom of a box of lenses, which is where I found it in the local used camera gear shop. And this wasn't a neatly organized box; it was a jumble.
What's unfortunate is that my work is sending me to Spain a couple weeks for a week or so and I'd love to have a good camera with me for shooting in my free time there. Instead I've got this. And renting for the time I'd need it ends up costing so much that it doesn't make much sense. I think I'll just take the 18-55.
I'll probably keep the Kalt just for messing with but I agree with your suggestion. I'll be in some major cities in June and may stop at some shops and see what I can luck into as far as a nice manual prime (I'd love an FA* 24 but I can't rationalize it at my level of experience).
