[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Simon: I have (on approval) a Viso II which has a similar problem: depressing the arm that links to the shutter release does not lift the mirror. I can lift it manually (or "digitally," I presume, since I have to poke it up with my fingertip), but the control lever will not raise it either. Recognizing that the mirror release for the II differs from that of the III, do you think the problem with this one could be related to the problem you fixed on yours? I am reluctant to disassemble a device that I do not yet own. Advice welcome. Thanks.///Dick Baznik __________ At 11:23 AM 6/29/99 +0100, Simon wrote: >...But when I checked it I found that however I adjusted the >screw on the arm the Viso mirror would not lift before the shutter when set >to the yellow-dot instant-up position. ... > >Completely baffled, and foreseeing a trip to the repairer, I recklessly took >the plunge and took the jeweller's screwdrivers to the Viso.
