I have not so good experience with Schneider customer service (Germany), you send them an email and then after some weeks you get a reply. In best case the reply makes sense and if you have to ask them again but this time there is no reply. This time I asked them what the cost would be to adjust the aperture blades for the 360/ 6,8 symmar-S, I got a reply and they asked what shutter the lens had. OK. I gave them the info and.... "The Prontor-3 shutter is leaked since 10 years. Spare parts are not available anymore. The lenses are leaked since 20 years. I´m sorry that I couldn`t help you in this matter." GRRRR!! I asked for a adjustment for the aperture and nothing else, maybe the customer service dosen't know how a LF lens is working? Anybody with same experience with Schneider? Is Rodenstock service better?
