I have one with the same problem - the diaphragm is oily and even after
fixing it (cleaning with solvent) it was sticking a few days later.
If you find a good DIY solution let me know, 'cos I like the lens - I still
use it ('cos at long focal length we're often looking for fast shutter
(i.e. wide-open aperture) aren't we?) - it looks very much like the Zuiko
65-200 f4 and I'm going to get one of those to replace it one day.

It is a fault, but maybe just a problem with the DOF button. Try setting
the lens to f22 and moving one of the two levers on the back of the lens
mount. If the lens stops down OK, it is just a DOF button problem.

Can someone confirm
for me whether this is a fault, or whether I have missed something obvious
here !! If it's a fault, I assume it wouldn't be advisable to attempt a
repair myself ? I am pretty competent with engineering, especially tiny
stuff, but I know little about lenses and their internal construction. And
it's not my lens - it's my Dad's !! Boy am I going to be in trouble !!
Anyway, any help gratefully received.
Regards,
Jon
