K-mount. Manual focusing. Dangerous for the K-5. Cool for the K-01.

Well...let'see...

• K50 f/1.2 is not all that obscure, they come up for sale every couple of weeks or so, but it's interesting because of the speed.
  
  
• K15 f/3.5 (AL) is more obscure, it's interesting because of it's applicablity on the APS-C crop format.
  
  
• K135 f/2.5 you already tested, it's interesting as a head-to-head reference against the old sensor.
  
  
• The K30/2.8 is obscure and has a lot of fan boys. But I don't think it would be interesting to PZ.
  
  

...Gonna guess the K50 f/1.2...might be pretty fun with the focus peaking on the K-01.
