I recently got my Rolleiflex back from service. It had some oil on the shutter blades and a tendency to get stuck open when it was cold outside. There was also an issue with the depth of field scale that needed to be corrected. The service was performed by Jonas Vikström at Analoga kameror Stockholm, who did an excellent job. If you are located in Sweden, and have a camera with either a Compur or Copal shutter, or a Leica, don’t hesitate to send it to him. He is a really nice guy, and has a deep passion for vintage camera gear.
