 The tools for producing the new shutter
mechanism were built by Prontor, a Zeiss subsidiary company in Calmbach, which had already taken over the manufacturing of the former shutter from Compur (another Zeiss subsidiary).When introducing the "Rollei 35 S" the former "Rollei 35" was assigned the new name "Rollei 35 T", without any further changes.A projected denim covered design variant, with an appropriate denim bag, was rejected because the textile covering frayed.
