Oil on aperture blades in OLYMPUS G.ZUIKO Auto-S 55mm 1:1.2____PART_1_Motion Lapse Film

There was A LOT oil on aperture blades in this OLYMPUS G.ZUIKO Auto-S 55mm 1:1.2.

I did not have the service manual for this lens, and therefore it makes it a little more difficult to repair, but now it work's like new :-)

It's a little different made aperture system in this compare to other lenses from Olympus, or other lens brands.

The front lens group on this model sit SO TIGHT, so use a big lens spanner to unscrew it.
Remember also to set mark's on the ring with the little tap, that goes into the aperture system.
The blades and the most inner aperture ring are putting back in a different way, because there is only 1 tap and 1 hole.

I did it a little wrong when putting back the 2 aperture rings on the backside of the lens, (from the bajonet), but I fix it anyway the second time.
