Thank you all for the advice and info. I will probably try to dig into it a little deeper over the weekend. I'll keep you guys posted...

I finally gave the small lever a little more than a gentle nudge and got it to stop down. This is what I've got. Looks like there is pretty good build up of oil on the blades as suspected. They are very stiff and once I have it stopped down, it will only open it up once. Now I have to figure out how to get deeper into the lens.
Again, I thank you all.

Here is that same lever on mine (blue arrow). I has about 1/8" of travel if I nudge it with the tip of my screwdriver. The lever with the red arrow moves in conjunction with the aperture ring. I have moved both manually and the iris still does not move.
BTW, i appreciate you taking the time to help me with this. ;)

Here are a couple of shots of the lens. Like yours, it is made in Korea. I tried setting it to F/22, jiggling the aperture lever and tapping it, all to no avail.

Looks like I may have to take it apart. I'm not too worried about it as I have nothing invested in the lens, at best I'll fix it and at worst I'll at least have a learning experience.

Hi folks,
My name's Erik and I'm new to the forum and to Pentax camera equipment.
I was just given a K1000, a ZX-M and several Pentax lenses. I have never shot with Pentax though I remember my dad having a few when I was growing up and learning photography. I have recently been wanting to get back into shooting film, so I acquired this gear at just the right time. Along with them, I received a JCpenny 135mm 2.8 lens. After looking around the web, I see several lenses like this one and it seems that the majority have a 55mm filter thread, mine has a 52mm thread. Anyway, it appears that the aperture ring is not engaging the iris. It will move and click home at all the apertures but the iris is not closing. (it seems to be stuck at f/2.8). Does anyone have any experience with this lens or could shed some light on this for me?
Thanks in advance,
-Erik-
