Zoom-Man is the first camera produced by Sigma

In the face of the prevailing competition movement recently at the level of automatic-manual cameras with a preferred aperture. Sigma, the well-known Japanese lens manufacturer, has entered this door to present a reflex camera of this type under the name (1-SA).
On this basis, Sigma's products are no longer limited to the production of the well-known series of lenses. Rather, it has announced a new branch that will enter the camera market, and this is the first lens company to do so.

Naturally, the SA-1 camera comes with a special lens made by Sigma, but this lens is not a normal 50mm lens, but a 35-70 zoom. Sigma has chosen one name for its camera, which is attached to this lens, which is Zoom Man, or Zoom Man.

And if some companies had previously installed a camera with a zoom lens, then the sigma considered that it would succeed, as others failed to provide what would encourage the consumer to buy a camera of this type.

- Specifications
The SA-1 camera, as we mentioned, is automatic and manual, with exposures at a preferred aperture and speeds ranging from 16 seconds to 1/1000 of a second. In addition to manual selection, the camera features a timer
Self-timer, battery detector, depth-of-field pre-review grab, and exposure memory switch. In the base there are two 1.5-volt silver oxide batteries to provide power for the counter, viewfinder, self-timer, electronic shutter and display. In order to save on the consumption of the two batteries, there is a power cut-off switch integrated with the shutter speed dial.

As for the accessories available for this camera (1 - SA) or - Zoom Man, it includes an automatic winder that advances the film two feet per second. And a specialized flash unit (AS240) - guide number 24 with 100-ar film - and the back of an information recording (Quarts SA), in addition to a neck strap and a solid transport bag.

- the design
The top page of the camera contains operating dials and knobs that are easy to grip and handle. To the far left, the film speed dial surrounds the rewinding crank. The film speed range ranges from 12 to 3200 ara. On the dial are exposure compensation locations that can be adjusted to lock in to over or under. Of the two stops for the calibrated exposure, there are implied third-stop stops that give an audio signal - a tick - to determine its location.

Following on the top page, below the Pentaprism body line, is the location of the self-timer, a timer that can be canceled and operated with an audible buzzer and flashing red valve at the front of the camera. At the top of the lens lies a quick-impact shoe for specialist flash exposures with a sigma unit. To the right lies a dial. Shutter speed and shutter speeds range from
1/1000 to 8 seconds in manual exposure, and it is, tack, in position with the lock and (B) positions.

As for the right side of the upper page, we find the movie presentation grip, and its work is incompatible with the electro-magnetic-noise shutter, and there is a frame counter that completes the contents of the upper page. Then, for ease of handling, I placed and cinema, easy (sports) grips in the front and back of the camera
For more stability. Within the grip on the front of the camera is an exposure memory switch.
Other features include a depth-of-field pre-review grip, a self-timer indication, a counter operation switch, and a flash sync quarry.

- Specified view
With the limited aperture of the lens, we find that the image of the viewfinder is reasonable in luster, and the focus is achieved through precise prismatic lenses that divide the image, with a semi-transparent screen. At the bottom there is a special window (Judas) that gives a direct reading of the aperture. To the right of the viewfinder there is a shutter speed scale of 1/100 to one second - indicating the shutter speed chosen by the camera according to the aperture desired by the photographer. Slower shutter speeds - 1/30 to 1 second - are indicated in orange, while at the base of the scale there is (LT) in red for speeds slower than a second.
There are also warning signs of exposures that are too low or too high, through flashing indicators above and below the scale.
When using the camera with its manual system, the needle is aligned with the shutter speed chosen to obtain this
On a correct exposure, warnings (over) or (under) should be used - plus or less for the exposure, as it is necessary to adjust when any warning of them appears.

- Zoom lens - Master
Sigma chose the (Pentax K) mount for its new camera - Zoom-Man, giving a maximum choice of additional lenses for the camera.
And . The Zoom-Master 35-70mm is a compact, lightweight lens that accommodates a standard focal length with a moderate wide angle and telephoto option.
It provides an aperture range from f/2.8 to f/22. As for the emphasis in the Pantix style, it is a tuck to the right until the end ⏹
