The camera has the following advantages. Semi-automatic exposure metering device with measurement of light passing through the lens (TTL system), ensures the correct exposure is set both when shooting with a standard lens and when using interchangeable lenses, filters, attachment lenses, extension rings.
Luminous diodes in the viewfinder, signaling the correct exposure setting, are equally visible both with the lens at full aperture and with its aperture. A constant-sight mirror makes it possible to continuously observe the subject before and after exposure. The fast lens is equipped with a jumping aperture mechanism that automatically closes when the shutter is released. A fully open aperture ensures maximum brightness of the image viewed in the viewfinder, which is important at the time of sighting and focusing.
Focusing using a combined focusing system allows you to obtain maximum image clarity in various shooting conditions. Quick exposure setting, simplified film loading, a self-resetting counter that is automatically set to the initial position when you press the rewind button, reduce the time spent on preparatory operations when shooting. The built-in self-timer allows the photographer to take a photo among friends or get a self-portrait. Hidden lock of the back cover, interlocked with the rewind head, increases the reliability of locking the back cover and the convenience of discharging the device. The presence of a plug socket and a central contact allows the use of flash lamps with both cable and cableless connections.
The retractable rewind button simplifies the process of rewinding the film. A pocket on the device allows the photographer to insert a reminder about the film with which the device is currently loaded. Please read this manual carefully before using the camera.
