The Mamiya C series (including the C2, C3, C220, and C330) was legendary for being one of the few medium format TLR camera systems featuring interchangeable lens boards. The Mamiya-Sekor 135mm f/4.5 telephoto set offers a classic portrait focal length on 6x6 film (roughly equivalent to a 75mm lens on 35mm format), making it an ideal choice for tight framing and headshots.
The unit mounts as a dual-lens assembly: the upper viewing lens feeds the waist-level viewfinder, while the lower taking lens houses a mechanical Seikosha leaf shutter offering speeds from 1s to 1/500s plus Bulb and M/X flash sync. Since it uses a leaf shutter, full flash synchronization is achieved across all shutter speeds. Supplied with its matching protective storage case.
