I am trying to access the aperture in order to clean oily aperture blades on a Topcor 58 1.4. I took out the optical block and the expectation is that the rear optical block screws out as a group. That happened as expected. The expectation that the front optical block screws out as a group is not happening. I applied a good amount of force, but only the ring holding the front element has come off. I need the whole optical group to unscrew. Any suggestions or techniques?
