Special Features of the Bronica RF 645
·A medium format
The Bronica RF 645 is a very compact and lightweight camera with a picture area approxi- mately 2.7 times larger than the 35mm format. The superior portability and versatility of this model compared with other medium format cameras ushers in an entirely new world of photographic possibilities.
·The remarkable lens shutter system
The electronically controlled #00 type lens shutter system developed for the Bronica RF 645 commands precise shutter speed control and automatic cocking, as well as aperture control incorporated within the shutter unit. The interface between the main camera body and the lens are conducted by means of a series of electronic contracts, resulting in high precision operation compared with conventional systems operated by mechanical couplers. The highly advanced lens shutter system is impressively stable and free of jolts caused by shut- ter shock, while it ensures synchronization with an electronic flash at any shutter speed allowing sophisticated flash photography.
·Automatic light shielding curtain engaged during lens interchange.
A lens shutter camera with interchangeable lens capability would normally require a light shielding curtain to be activated manually prior to detachment of the lens. The Bronica RF 645 had made such complex and awkward steps unnecessary, enabling photographers to focus on the shooting itself. In conjunction with the lens detachment operation, the light shielding curtain automatically covers the film aperture and locks into place. When the next lens is mounted on the camera, the curtain automatically opens to prepare the camera for the next shooting.
·Hi-tech magnesium alloy Thixmolding
The top cover of the Bronica RF 645, a lightweight and extremely sturdy camera, is manufac- tured with an advanced Thixmolding technique. This technology enables a hard and rigid magnesium alloy to be molded into intricate and complex forms required to hold and pro- tect internal mechanism with precision in various, at times even adverse, operating condi- tions.
·Rear cover design provides sophisticated controls with easy access and handling.
Switches and dials on the rear cover are grouped together on the rear cover for easy han- dling and to enable confirmation of settings at a glance, an extremely important feature for use in the hands of serious photographers.
