The Müller Einwegkamera (also known as Müller Einwegkamera ISO400-27) is an analog disposable 35mm film camera distributed as a private label by the German drugstore chain Müller. The model is designed for uncomplicated photography and is particularly used at events such as weddings, parties, or on trips for spontaneous shots.
Functions
The camera model has a fixed built-in lens. Since it is a fixed-focus optic, there is no way to manually adjust sharpness. The subject is automatically sharp from a manufacturer-specified minimum distance to infinity, so precise distance setting is not required.
Furthermore, the camera does not have a built-in light meter. Since aperture and shutter speed are fixed, manual exposure metering or adjustment is not provided.
To achieve sufficiently exposed images even in difficult or insufficient lighting conditions, a manually switchable flash is integrated into the body.
The power supply for the flash is ensured by a built-in battery. The recording medium is an integrated color negative film in 35mm format with a light sensitivity of ISO 400, designed for 27 exposures.
Distribution
The Müller drugstore chain offers the model as part of its photo private label range. These cameras are usually manufactured by specialized suppliers on behalf of the retail company. The manufacturer is indicated as GBT GmbH. The price in 2026 is 14.99 euros. It is available in two designs.

Film development and image processing
Since the film is permanently installed in the camera and cannot be easily removed by yourself after photographing, after exposing all 27 shots, the entire camera is submitted for film development. This can be done directly in the branches of the drugstore chain via the Müller photo service.
In the large-scale laboratory, the body is opened mechanically to remove the exposed film. This is then subjected to a classic chemical development process. Customers receive the finished images either as physical paper prints, on a digital data carrier, or via online download.
