But alternating jamming? And not in every sequence? Single shots are always the same exposure.

The lever on the camera pushes the aperture open when in rest. You take a shot and the lever comes down where a spring pushes the aperture closed to f/8. If the mechanism (or the aperture blades) are slightly sticky the aperture won't open fully all the time (only sometimes) to the set value. I guess that's the problem here.

You can test it by manually flicking the aperture lever on the lens by hand, although the effect may be too subtle to notice. Compare with other lenses.
