ZEISS IKON CONTAFLEX II

Name: Zeiss Contaflex II
Brand: Zeiss

The Zeiss Ikon Contaflex II is a 35mm single-lens reflex (SLR) camera introduced in 1954. It is the original Contaflex I with a built-in, coupled selenium light meter added. That made it one of the earliest metered SLRs in the German precision camera market, and it gave amateur and professional photographers better exposure accuracy.

Overview

The Contaflex II was produced by Zeiss Ikon in Stuttgart, West Germany, during a period of rapid innovation in 35mm photography. Released between 1954 and 1958, it represented the second generation of the Contaflex series, which began with the non-metered Contaflex I in 1953. The Contaflex line was notable for its compact, rigid body design and fixed lens configuration, departing from the interchangeable-lens norm of many contemporary SLRs. The Contaflex II targeted serious amateur photographers and professionals seeking reliable, high-quality optics in a relatively compact SLR format.

The integrated selenium-cell exposure meter was coupled to the aperture mechanism - making it one of the first SLRs to offer through-the-lens (TTL) metering via a selenium cell mounted around the lens barrel. It removed the need for a handheld meter and improved exposure precision under variable light. The camera kept the leaf shutter inside the lens, which allows flash synchronization at all shutter speeds. Focal-plane-shutter SLRs of the era could not do that.

The Contaflex II was part of Zeiss Ikon’s strategy to turn post-war German optical excellence into accessible, precision-engineered cameras. It shared design lineage with other Zeiss Ikon models like the Contax rangefinders but carved a niche as a high-end, fixed-lens SLR. The body is die-cast aluminum with leatherette covering. It has a folding waist-level finder and a rigid, non-interchangeable lens mount that put optical alignment and mechanical stability ahead of modularity.

Key Features

Coupled Selenium Light Meter: One of the first SLRs with a built-in, TTL-coupled selenium meter, eliminating external metering needs.
Leaf Shutter Design: Compur-Rapid shutter located in the lens allows flash sync at all speeds (up to 1/500 sec).
Fixed High-Quality Tessar Lens: 45mm f/2.8 Zeiss-Opton Tessar provides sharp, contrast-rich images with minimal aberration.
Compact and Rugged Build: Die-cast body with folding finder enables portability without sacrificing durability.
Manual Precision Controls: Direct aperture and shutter speed dials offer tactile, intuitive operation favored by experienced photographers.

Historical Context

The Contaflex II launched when 35mm SLRs were moving from niche technical tools to mainstream creative instruments. Its main competition was early Japanese SLRs like the Asahiflex and the Miranda T, plus the more advanced but larger Exakta VX. The Contaflex II set itself apart with German optical engineering and its metering. The selenium meter is prone to degradation over decades, but in 1954 it was a cutting-edge feature and put Zeiss Ikon at the forefront of exposure automation.

Despite its advanced features, the Contaflex II had a conservative design. Unlike the Exakta or later Praktica models, it did not support interchangeable lenses, which limited its appeal to purists who valued optical integrity over versatility. Its metering system and leaf shutter still gave real advantages in studio and flash photography, where consistent sync and accurate exposure were paramount. European professionals received it well. Its high price and lack of a prism finder limited broader adoption, especially in the U.S. market.

Collectibility & Value

Today the Contaflex II is a sought-after collector’s item, particularly among enthusiasts of vintage German optics and early metered cameras. Units in excellent working condition with a responsive meter typically fetch between $400 and $700 on the secondary market, and a fully functional selenium cell is a key determinant of value. Rarity is moderate. It is not exceptionally scarce, but many units suffer from degraded meter cells or stiff shutters from age and lack of use.

When buying a Contaflex II, inspect the selenium cell for flaking or darkening, test shutter speeds with a timer, and check for smooth film advance and accurate frame spacing. Common issues include sticky aperture blades, worn shutter curtains, and cloudy viewfinder screens. The lens is fixed, so optical fogging or internal scratches can significantly reduce value. Servicing is hard because the lens, shutter and meter are one integrated assembly. It takes technicians familiar with vintage leaf shutters and selenium meter systems.

Konica IIA (1956) – A high-end rangefinder with metering, though not an SLR, sharing the Contaflex II’s focus on compact design and precision.
Exakta VX (1950) – German SLR with interchangeable lenses and focal-plane shutter; more versatile but bulkier and without built-in metering.
Asahiflex IIb (1957) – Early Japanese SLR with interchangeable lenses; lacked metering but offered greater system flexibility.
Praktina FX (1952) – Modular 35mm SLR system with interchangeable lenses and focal-plane shutter, favored by press photographers.
Alpa-Reflex (1949–1953) – Swiss-made precision SLR with modular design and high-grade optics, comparable in quality but significantly more expensive.

Repair & Maintenance

The Contaflex II needs no batteries, since its selenium meter operates passively. Selenium cells degrade over time, often losing sensitivity or failing entirely. Replacement is not feasible, though some technicians retrofit modern CdS cells with external circuits. The Compur-Rapid shutter is serviceable but delicate - common issues include slow speeds, second-curtain drag, and misfires at high speeds. Lubrication of the film transport and aperture linkage is essential after long dormancy. Because the lens is fixed, disassembly for shutter or meter repair involves complex recalibration. Professional servicing is recommended, particularly for meter alignment and shutter timing.
