help! new lens won't work on old dslr?

I am using a beat-up old pentax k200d. I've been using it with the old manual lenses I had from my trusty k1000. I decided to splurge for a new lens yesterday and got the smc pentax DA 35mm 2.4AL. I can't get it to work on my k200d. It won't adjust aperture at all. I've messed with settings all day with no luck. Is it not compatible?

Buff the contacts on the body lightly with a microfiber cloth and try it again.

That helped a little --- I was able to get it to focus and take pictures but only in bright outdoor light. It still won't open up the aperture.

So it's supposed to be compatible but my camera is just not working? Highly possible --- it is rather beat up.

What other lens(es) do you use on your K200? If you do have/use other DA lenses, and they work ok, then it could be a problem with the DA35. Try cleaning the contacts on it, as you did on the camera body.

Also, as you mention using old film era lenses, you might want to check the settings on your K200. I can't help with which ones, or even if they matter, but setting up your camera for manual lenses might have affected how non-manual lenses perform.
