Sigma Sigma SA-7 35mm Film Camera

Although it has a lightweight and ultra-compact body, the SA-7 camera sports versatile functions for taking beautiful pictures. The SA-7 is a full-fledged, single-lens reflex camera that is rugged, versatile and easy to use for beginners to photo enthusiasts.

With an AF-cross sensor in the center of the viewfinder, the camera has fast focusing capability and is easy to use. The SA-7's autofocus system also features a predictive AF function in the Continuous AF Mode, that lets the photographer capture a moving subject in sharp focus. This ensures optimum focus when taking pictures of subjects moving towards or away from you at constant speed. It will latch onto subjects between infinity and 26.4 feet (8 meters) moving as quickly as 30 miles per hour (50 kilometers per hour), up from 25 miles per hour (42 kilometers per hour).

The camera automatically sets shutter speed and aperture, based on the brightness of the subject, to ensure optimum exposure in [P] Program Auto. The image is divided into 8 segments, and the light intensity of each segment is measured independently. An optimum exposure is calculated based on the information obtained by this 8-segment evaluative metering. In Single AF-Mode, pressing the shutter button halfway down starts the camera operation. The focus lock (AF lock)/AE lock function is activated to lock the focus on the subject and then picture can be taken by pressing the shutter button all the way down.

When Program Auto mode is used, turning the Command dial activates temporarily Aperture-Priority auto mode (Program Shift). The command dial also allows the setting of various functions when used in conjunction with other dials or function buttons. Since shutter dial and mode selector are located in the same area, choosing the desired settings is very convenient and smooth.

An AF internal lens motor drive provides the best performance for AF operation of a lens. Thus, AF internal lens motor drive of the Sigma system ensures ideal focusing operation for more than 40 different types of Sigma lenses including hypersonic motor (HSM) lenses. Use of Sigma lenses equipped with a hypersonic motor (HSM) ensures high speed focusing with minimal operating sound. The continuous AF Mode lets enables the photographer to capture a moving subject in sharp focus. This ensures optimum focus when taking pictures of moving subjects moving towards or away from you at constant speed. It will latch onto subjects between infinity and 26.4 feet (8 meters) moving as quickly as 30 miles per hour (50 kilometers per hour), up from 25 miles per hour (42 kilometers per hour).

The built-in flash employs a TTL auto light control system covering the angle of 28mm lens with a Guide Number 40/ft (12/m) ISO 100. When flash is required for indoor shooting due to insufficient light, the flash indicator in the viewfinder blinks. When the flash is used to take a picture of people, the red-eye reduction mode minimizes the

Diopter adjustment over a range of 1.5 Diopt. 3 Metering Systems (8-Segment Evaluative Metering, Area Metering, Average Metering).
