KMZ Start1958

History

KMZ entered SLR production in the early 1950s with the Zenit, a body derived from the Zorki rangefinder chassis adapted with a reflex mirror box. The Zenit line was functional and produced in large numbers but was positioned as an accessible amateur design. By the late 1950s KMZ developed the Start as a distinct, more ambitious SLR intended for the professional and advanced-amateur market. The Start introduced the interchangeable viewfinder system to Soviet SLR production - a design choice that acknowledged the influence of contemporaneous professional Western SLRs. The camera launched in 1958 and remained in limited production into the early 1960s. It did not achieve the mass-market volumes of the Zenit line, and production ceased without a direct successor that inherited the interchangeable-finder system. KMZ continued the Zenit line instead, with the Zenit-3M and later models carrying the mainstream SLR output.

Why It Matters

The Start is a significant outlier in Soviet camera history. While the Zenit series pursued volume and accessibility, the Start pursued specification and flexibility. The interchangeable viewfinder system gave the camera a degree of professional adaptability unusual in Soviet production - operators could swap between eye-level pentaprism and waist-level finder configurations depending on shooting conditions, a feature that professional photographers in the West had come to expect from top-tier bodies. The Start therefore represents a moment when KMZ demonstrated it could engineer at the level required for a professional product, even if the market conditions and production priorities of the Soviet system meant it would not follow through with a sustained professional SLR line. For collectors, the Start is one of the rarest and most technically interesting Soviet 35mm SLRs.

Lenses & Accessories

The KMZ Start uses an M39 screw mount dimensioned for SLR (not rangefinder) registration. Key considerations:

• Native lenses. Helios-44 58mm f/2 is the standard lens most commonly associated with the Start and contemporary KMZ SLRs. Industar-50 and Industar-61 serve as normal and semi-wide options.
• M39 rangefinder lenses. Cannot be used at infinity focus without adaptation due to register distance mismatch. Macro distances only without correction.
• Interchangeable finders. Pentaprism eye-level finder standard. Waist-level finder produced for the Start.
• No TTL metering accessories were produced for the Start; external metering required.

Sample Photographers / Notable Use

• Used within the Soviet professional and advanced-amateur photographic community in the late 1950s and early 1960s.
• Represents the peak of KMZ's 35mm SLR engineering ambition before the Zenit line absorbed all SLR production focus.
