Award-winning lens maker Sigma has now designed an excellent autofocus SLR camera with the end user in mind. The dial-controlled SA-7 is a full-fledged SLR with a host of advanced features, including a healthy range of exposure modes and metering modes, a built-in flash, self-timer, LCD information panel, built-in motor drive for automatic film advance/rewind, and more. The Sigma SA-7 also maximizes maneuverability with its durable yet lightweight body that ensures great performance under demanding conditions. This SA-7 kit comes complete with a quality 28-80mm Sigma AF zoom lens and a handsome Sigma brand camera bag. It is important to note that the SA-7 is only compatible with Sigma's SA mount lenses.
Of course, given that Sigma is originally a lens manufacturer, one of the strongest features of the SA-7 is its autofocus system. Focusing with the SA-7 is simple--just place your subject in the center of the viewfinder and slightly depress the shutter button. The super-quiet hypersonic motor works with the AF cross sensor to do the rest, all in a split second with pinpoint accuracy. The autofocus system also features a sophisticated motion prediction mode that allows subjects moving at a constant speed to be captured in sharp focus. It calculates the time required for the shutter to open after the shutter button is pressed, then automatically adjusts the focus at the point where the subject will be located when the shutter opens. In Single AF mode, a focus-lock function is activated that locks your focus on the subject. The camera signals you when focus is achieved with a light indicator in the viewfinder and an electronic sound. With symbols and color, the viewfinder also displays other necessary information. The LCD panel atop the camera body gives you shooting information, as well.
The SA-7 features fairly intuitive dial controls, offering the ability to go from fully automatic to manual mode with just a few quick adjustments. For manual operation, there is a shutter dial so you can set your shutter speed, either to Bulb or anywhere from 1/2,000 to 4 seconds. A command dial controls various settings such as adjusting aperture when in aperture-priority auto mode. The drive dial controls fine adjustment functions, which include continuous shooting, auto bracketing, mirror lock-up, and self-timer.
There is an eight-segment metering mode that divides the image into eight sections, measuring the light separately for each section and calculating an optimum exposure value for the whole scene. Another notable feature is the ability to capture fluid action at 1.5 frames per second with one depress of the shutter button. Finally, the camera boasts a diopter adjustment, a preview button to confirm depth of field, midroll rewind, a total of three metering systems, four exposure modes, multiple exposure function for special effects, and integrated flash with red eye-reduction.
