| Zenit 3 type 2a (1962) |
Image by Süleyman Demir
Zenit 3 is a 35mm film SLR camera manufactured by Krasnogorsky Mekhanichesky Zavod (KMZ), Mechanical Factory of Krasnogorsk, in Moscow, former USSR and produced between 1960-62, quantitiy 81776. Zenit (Зенит = Зенит), means Zenith, a point in the sky that appears directly above the observer. On front of the camera Zenit logo is engraved as cyrillic italics.
Zenit 3 is the third model of Zenit brand and is successor to the first model Zenit (1953-56) and the second model Zenit S,(1955-61) and main differences between them are added selftimer and shutter cocking lever instead of a knob.
Early models of the Zenit cameras were based on the Zorki rangefinder camera (a copy of the Leica II). In transforming the Zorki into an SLR, the simplest approach was taken: the rangefinder housing was removed from the top and replaced by a ground-glass screen and prism; a mirror was added below, with a rope-and-pulley setting system and the M39 thread mount was pushed forward to make room for the mirror inside.
During the first years of production, until the Zenit E of 1967, Zenit camera development coincided with that of the Zorki cameras.
The Zenit 3 shows outstanding workmanship, the camera is very solid and was apparently expensive to make. This explains why it was in production for only two years. As any early Zenit it is quite uncommon now.
