Had the same problem with one I bought from ebay, the seller sent me an 
A version to replace the bad M version.

Hello all,

Today, I've received my 'new' M2.8/35 mm and the aperture closes
extremely slow. I had just discarded another lens of this type for
exactly the same reason. Never had such trouble with any of my other
Pentax lenses. 

Is there something about the 2.8/35 mm?
