Automate translation from Wikipedia:
"Start" is a Soviet small format single-lens reflex camera made by the Krasnogorsk Mechanical Plant in 1958-1964. A total of 76,503 pcs.
The type of photographic material used is a perforated photographic film 35 mm wide (film type 135) in cassettes. Instead of the receiving coil, a second cassette can be installed. The design of sliding latch locks allows, in addition to standard cassettes, two-cylinder cassettes of the "Contax" type [4]. This cassette consists of two cylinders inserted into each other. When locking the lock, the inner cylinder turns and opens a wide gap. The film passes through it, without touching the edges and without scratching.
The frame size is 24 × 36 mm.
The type of the shutter is mechanical, curtain-slit with horizontal movement of the cloth shutters. Shutter speeds are from 1 to 1/1000 s (automatic), "B" (by hand) and long (not available with a standard lens). The synchronization delay with flash lamps is 1/25 s [5].
The type of attachment lens - the original bayonet with a union nut. The camera was equipped with an adapter that allowed using lenses with M39 × 1 / 45.2 mm threaded mount (from Zenit cameras) [6].
The working section of the chamber is 42 mm.
The size of the field of the viewfinder image is 22 × 33 mm [5].
Type of focusing screen - frosted glass with focusing wedges. There were also screens without wedges, but they were not widely used.
Pentaprism - removable, can be replaced by a mine. The increase in the pentaprism eyepiece is 5 ×
To synchronize with the flash units, two sync contacts are installed: "X" - for connecting electronic and disposable quick-burning flash-lamps and "M" for slow-charging lamps.
The thread of the tripod socket is 3/8 ".
The back cover is completely removable, with two locks.
The standard lens - "Helios-44" 2/58 mm with the mechanism of pressure diaphragm: when you press the shutter release button it closes to the working value. The aperture button, located on the lens rim, is connected to the trigger on the front wall of the camera by the type of Exakta cameras. It was possible to turn off the jumping diaphragm: when the shutter release button was pressed on the lens, the aperture was set to the operating value. On the shutter release button there was also a tapered thread under the trigger cable, because of the increased descent force, a cable with double protruding finger supports was recommended.
Weight with a lens "Helios-44", pentaprism, cassettes and a case - 1300.
A knife is provided for cutting off the filmed part of the film and a mechanical self-timer.
The mirror is lowered only when the shutter is cocked.
