Yes, it looks like a Sigma lens. 'Pantel' seems to indicate that it
stops down to f/64, though I'd think diffraction would cause it to be
pretty soft there. Often you can fix the aperture by taking the back
mount off and seeing where the linkage is disconnected. You need some
small screwdrivers and a bit of dexterity. Not having an aversion to
possibly ruining the lens also helps :) As others have said, it's
probably not worth paying someone to fix it, but it can probably be
pretty easily repaired.
For OM mount lenses, only one button is needed to remove the lens.
The other button is the DOF preview button, which as you have found
stops the lens down so you can see what effect the aperture setting
has.
