The King Regula Rotor-S is a viewfinder camera. It was introduced in the 70s. The model was built by the family business King from Bad Liebenzell. The range of functions is identical with the King Regula Picca C.
The lens of the King Regula Rotor-S cannot be exchanged. The focal length is 40 mm and the maximum aperture is f/2.8. The lens is called “Color-Isconar 40mm f/2.8”.
The King Regula Rotor-S has been designed with a high degree of manual control that allows photographers to personalise their shots. This manual focusing system means that the user must manually adjust the focus of the lens to ensure that the subject is in focus. While this requires some skill and practice, it also gives the photographer more control over the final image and can be particularly useful in situations where autofocus struggles, such as low light or low contrast.
Although the camera has a window for a selfexposure meter, there is nothing behind it. This means that photographers must use an external light meter or rely on their own experience to determine the correct exposure settings for their shots.
The King Regula Rotor-S also has a Bulb mode that allows for long exposures. This mode is particularly useful in low-light situations where the camera’s normal shutter speeds are not sufficient to capture the desired image.
An external flash can be used via the hot shoe. In addition, the camera has a thread for a tripod, which can help stabilise the camera for longer exposure times or when shooting in low light conditions.
One advantage of the King Regula Rotor-S is that it does not need a power source to take pictures.
Films for the King Regula Rotor-S
The King Regula Rotor-S is designed for 35mm films. The 35mm format is the most common film format. Therefore, some manufacturers still produce for this format. Two great films for the 35mm camera are the Kodak Portra 160* and the Ilford HP5*. Both can be used to take beautiful color or black and white pictures.
The development process for the color film is the C-41 process. The C-41 films are offered by most photo laboratories.
The film in the camera must be winded manually, as there is no automatic film transport.
The model is nowadays only available trough the used market. The prices for the camera vary depending on the condition.
