Soligor 200mm Tele-Auto f/2.8 in M42

2009-02-20 Posted by Hin Man
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.

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:
  1. Use some way to jam the pin with cotton swap
    - Converting Auto-Aperture M42 Lens to Manual Aperture on Flickr - Photo Sharing!

  2. 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

  3. Use of Kindai M42 to K mount adapter
    - Helios 44m-5 is good for k10d?
    - thanks to Frank for the suggestion
