I've had my Zeiss Ikonta IV CLA'd by Essex Camera Repair a couple of years ago. I've sent it back once because the shutter jammed and it was under warranty. Now it jammed again. Both times I've shot in the cold. Don't know if it's related. I'm trying to find a new repair facility. I've been emailing Bald Mountain and the person doesn't respond quickly. Also he hasn't responded to my last email. I don't sense enthusiasm here. Can someone recommend a good repair facility that will repair the shutter on my old gem?
