I want to be clear about my question asking for addition Rollei repair facilities; I have gone to Onick, I quite agree he is great to deal with, and funny as well. The problem, my problem, is that Onick does not have a Hy6 to test my problem lens with - 90 mm Macro which has a aperture iris that keeps moving instead of settling down to the desired f-stop when the lens is set to the AUTO mode. This is not the case with the iris, when the lens is in the directly selected f-stop mode.
So, please know this is not in any way a sign of my dissatisfaction with Onick.
