Lenses
Lens interchange is supported by the 35mm camera and allows the use of lenses with Minolta A bayonet. Various lenses with different focal lengths are available, including zoom lenses as well as fixed focal length lenses.
Autofocus
The camera’s autofocus is designed to enable sharp and focused photos effortlessly. With advanced technology, it automatically adjusts focus based on the subject and lighting conditions to ensure that subjects are always in focus.
The built-in LED AF illuminator is a convenient feature that automatically activates in challenging low-light or low-contrast situations, assisting autofocus with additional light. Versatile AF control options, including single, continuous and auto AF modes, provide flexibility for different shooting situations and preferences.
Exposure Metering in 35mm Photo Cameras
There is a built-in light meter in 35mm still cameras that is designed for film with sensitivities ranging from ISO 6 to ISO 6400. The film speed of the loaded film can be read using a DX code on the film cartridge, supporting a range from ISO 25 to 5000.
Exposure Modes
The camera is equipped with various exposure modes. In P mode (program automatic), the shutter speed and aperture are set accordingly.
In P (Program Automatic) mode, the shutter speed and aperture are automatically set accordingly.
