I'm having some problems with my K 24/2.8. The lense is otherwise perfect (for my tastes anyway), but the aperture blades have decided not to budge below the in-between point of f11 and f8. The aperture ring does move though. I don't usually use an aperture that small with this lense, b/c i am usually hand holding w/ 100 film, and depth isn't much of an issue b/c its normally focused at infinity. Still, though, it is nice to know that my equipment works 100% the way it was built to. Any ideas about the cause of this, and suggestions for fixing it...at a relatively cheap price, considering its superficial worth to me.
