Handling this camera requires manual intervention as it does not have an autofocus function. Precise focusing requires conscious interaction with the environment, making the photographic process a more conscious experience. Furthermore, the Diramic RF100 offers the flexibility to change your lenses at will thanks to the inclusion of the M42 thread, a standardized and manufacturer-independent lens connection.
The Diramic RF100’s uncompromising mechanics continue to expand its capabilities. It allows photographers to individually adjust the aperture and exposure time in order to be able to react perfectly to the respective shooting conditions. The built-in exposure meter, which measures through the lens according to the TTL principle, does not require batteries, but can lose functionality over time.
Users will also appreciate the ability to achieve long exposures through the built-in bulb setting. This setting allows the shutter to be kept open for a variable duration, creating ideal conditions for experimental and artistic recordings. Complementing the camera’s versatility, the ability to connect an external flash via the PC flash socket is a welcome addition, offering expanded lighting options.
For solid stability and convenient handling, the Diramic RF100 can be mounted on a tripod. It also has a thread for a cable release and a self-timer function that offers additional flexibility when taking pictures.
