Hi CSers, need some help! Just bought a Leica M6 TTL 0.72 and attached a Summicron 35mm f/2 on it. The framelines are right at the edge of the viewfinder, almost like a 28mm framelines. From the literature I read (online and Leica M6 TTL instruction booklet), it doesn't seem right. And I am not wearing glasses. Does something seem out of place here? Appreciate your feedback.
