I can attest to the suggestion of Vivitar 200mm f/3.5, especially those made by Komine starting with serial number 28.
That lens comes in both K and M42 mount. I have the K mount and I wish I have the M42 mount as I don't mind using the M42 adapter. With the M42 mount version of the lens, I can shoot Av mode.

I recently got a Soligor 200mm f/2.8 in M42 mount. The lens is in pristine condition but I have not taken any shots from it except few product shots. My lens has a serial number starting with 37 and the lens may be related to Tokina as Vivitar brand has serial number starting 37 were manufactured by Tokina.
I fell short in showing a picture of the long pin sticking out of the M42 mount. This older M42 lens does't come with a A/M switch. It has a long pin sticking out with the aperture wide open and my K20D body won't depress it to the close down the blades according to aperture stops
I am planning to do some modification to make the lens manual permanently. I researched on various discussions with questions to all my buddies such as Mis, Peter, Frank, and few others from another forums, here is the summary of possible remedies:- Use some way to jam the pin with cotton swap
- Converting Auto-Aperture M42 Lens to Manual Aperture on Flickr - Photo Sharing!
- Crazy clue to press down the pin in position
- Peter reported success with Helios-44M
- Unfortunately, my pin is long and the spring seems very strong underneath
- Subject to glue used, possible to undo the change
- Use of Kindai M42 to K mount adapter

- thanks to Frank for the subjection
To OP, when you get your lens, make sure you have the A/M switch and you need to have the M switch for the K bodies to work; otherwise, you need to make the changes such as the above.
