Zhumell RF645 manual ·Easy AE lock method with continuous AE lock memory system

Special Features of the Bronica RF 645

·Shooting parameters of the camera are clearly indicated on the internal viewfinder display panel.

An oversized LCD panel is installed inside the viewfinder to display constantly updated shooting status data such as shutter speed, lens aperture, AE lock setting, exposure compen- sation setting, correct exposure setting and exposure deviations of manually set exposure values and so on.

·Easy AE lock method with continuous AE lock memory system

The AE lock feature of the Bronica RF 645 stores an exposure value into memory for an extended time without canceling it at a shutter click. The metered and stored exposure value can then be modified by the shutter speed and aperture combination variations, or even by compensating the stored exposure with exposure bracketing technique.

Note: Repeated activation of the AE lock memory may be limited by the remaining battery capacity.

Also, the AE lock memory will be automatically cancelled if the power is switched off or camera is left unused for five minutes.

·The dedicated automatic flash unit that cross-couples with the AE setting on the camera.

The dedicated AE flash unit, the Bronica Speedlight RF 20, specially designed for the RF645 camera body, is coupled with the camera control system. The unit utilizes the electronic contracts of the hotshoe on the camera to transmit and receive lens aperture values, the aperture control signals and other controls data, enabling the flash unit to compensate for the flash illumination by a half stop within -3 to ±2 exposure compensation range.
