Zenit is a Soviet camera brand manufactured by KMZ in the town of Krasnogorsk near Moscow since 1952 and by BelOMO in Belarus since the 1970s. The Zenit trademark is associated with 35mm SLR cameras. The early Zorki-based models were labelled Zenith in a handwritten style of script. The Zenit-E, produced between 1967 and 1969, is one of the most famous Zenits, with over 12 million produced. The Zenit-D is one of the rarest Zenit cameras, with only 63 cameras produced. While I could not find explicit information on whether Zenit ET cameras are mostly plastic, the Zenit 11, which is the successor of the Zenit ET, is described as having a light full metal body.

What You'll Learn
Zenit ET's plastic body
The Zenit ET is a 35mm SLR camera manufactured by KMZ in the town of Krasnogorsk, near Moscow, Russia. It is an evolution of the Zenit E, which was produced between 1967 and 1969, and the predecessor of the Zenit 11, which was produced from 1981 to 1990. The Zenit ET was produced between 1982 and 1993, with a total quantity of 3 million.
The Zenit ET has a simple, brick-like design with strong angles. It is not particularly attractive, but its workhorse design is functional and effective. The camera has a built-in selenium light meter, which is integrated into the camera in a way that makes it seem futuristic. The back of the camera has a big circular opening, which is inviting and allows for the use of many M42 lenses. The viewfinder is quite big, although it loses some light. The screen on the Zenit ET is a good size for nailing the focus on an SLR.
The Zenit ET has a manual shutter mode and a licensed 'Copal Square' shutter. Shutter speeds range from 1/2000 to 1 second, and up to 16 seconds in Auto mode. The camera also includes a semi-manual exposure counter with the shutter release button in the middle. The frame counter is not fully automatic and must be manually reset to the 0 position after loading a new film.
The Zenit ET is made of metal. While I cannot confirm whether any plastic components are used, it is described as having a "light" full metal body.

Plastic lens mount
The Zenit is a Soviet camera brand manufactured by KMZ in the town of Krasnogorsk near Moscow since 1952 and by BelOMO in Belarus since the 1970s. The Zenit-E, produced between 1967 and 1993, is one of the most popular Zenit cameras. It is a 35mm single-lens reflex (SLR) camera with a brick-like design and a selenium light meter. It features a built-in light meter, a large viewfinder, and a frame counter. The Zenit-E has an M42 screw mount, which allows for the mounting of various M42 lenses.
Despite the advantages of high-grade plastics, some photographers express concerns about the durability of plastic lens mounts, especially when compared to metal mounts. There are reports of plastic lens mounts breaking after cameras are dropped, even from a low height. Additionally, issues with auto-focus and IS motors failing have been attributed to plastic lens mounts, making repairs uneconomical.
While plastic lens mounts may be more susceptible to damage, they are not inherently inferior. The choice between a plastic or metal lens mount depends on various factors, including the intended use, the camera's expected lifespan, and the user's budget. For those seeking a long-lasting camera, a metal mount may be preferable due to its perceived durability. On the other hand, plastic lens mounts can offer cost savings and are suitable for those who plan to upgrade their camera equipment every few years.

Plastic viewfinder
The Zenit ET is a 35mm film SLR camera manufactured by Vileiskiy Zavod Zenit, a factory near Minsk in the former USSR. It was produced between 1982 and 1993, with 3 million units made. The Zenit ET is part of the long-running series of Zenit cameras, which were first manufactured in 1952 by KMZ in the town of Krasnogorsk, near Moscow.
Zenit cameras are known for their simple and effective design, with the Zenit-E being one of the most popular models. The Zenit ET's viewfinder is quite big, though smaller than what its large opening might suggest. It provides a clear view, although it does reduce the incoming light. The viewfinder includes a Fresnel glass screen, which some photographers prefer over other focusing assists. The back of the camera has a large circular opening, which invites users to view the world through the many M42 lenses that can be used with the Zenit ET.
The Zenit ET's plastic construction extends beyond its external parts, with many internal gears, levers, and pulleys also made from plastic. Despite this extensive use of plastic, the camera operates smoothly and quietly. The Zenit ET also features the first multi-coated lens in mass production.
Overall, the Zenit ET's plastic viewfinder and construction contribute to its functionality and popularity as a simple and effective camera.

Plastic shutter
One of the benefits of plastic shutters is their durability. Vinyl shutters are known for their ability to withstand harsh weather conditions and are often used as an exterior design element. They are also low-maintenance, requiring little to no upkeep, which makes them a convenient choice for homeowners. Additionally, vinyl shutters can be customised to fit any window size and shape, making them a versatile option for those looking for a quick and easy way to improve their home's curb appeal.
While plastic shutters offer a range of benefits, it is important to consider the environmental impact of vinyl or PVC (polyvinyl chloride). Vinyl is a type of plastic that is derived from petroleum and natural gas, both non-renewable resources. The production and disposal of vinyl can have negative environmental consequences, including the release of toxic chemicals and the contribution to greenhouse gas emissions. As a result, some individuals may prefer to explore alternative materials for their shutters, such as wood or aluminium.
When compared to other materials, plastic shutters may not offer the same level of insulation as their wooden or aluminium counterparts. This is an important consideration, especially for those living in extreme climates. However, advancements in technology have led to the development of vinyl shutters with improved insulation properties, providing an energy-efficient option for homeowners.
Overall, plastic shutters present a versatile and affordable option for those looking to enhance the exterior of their homes. With a range of styles and colours available, vinyl shutters can be customised to match any home's unique character. While environmental concerns surrounding vinyl cannot be overlooked, the popularity of plastic shutters among homeowners remains evident due to their durability, low maintenance, and aesthetic appeal.

Plastic production
Plastic is derived from natural, organic materials such as cellulose, coal, natural gas, salt, and crude oil. The production of plastics begins with the distillation of crude oil in an oil refinery, separating the heavy crude oil into lighter components called fractions. One of these fractions, naphtha, is crucial for plastic production. The two main processes used to produce plastics are polymerisation and polycondensation, both of which require specific catalysts. In a polymerisation reactor, monomers such as ethylene and propylene are linked to form long polymer chains.
The world's first fully synthetic plastic was Bakelite, invented in 1907 by Leo Baekeland, who coined the term "plastics". Plastic, derived from the Ancient Greek πλαστικός (plastikos), means "capable of being shaped or moulded". Plastics are classified by their chemical structure, chemical synthesis processes, physical properties, and resistance to various substances. Important groups include acrylics, polyesters, silicones, polyurethanes, and halogenated plastics.
The success of plastics since the early 20th century has had significant benefits, from medical devices to construction materials. However, plastic is also the basis of widespread environmental concerns due to its slow decomposition rate. Between 1950 and 2017, an estimated 9.2 billion metric tons of plastic were produced, with more than half made since 2004. In 2023, over 400 million metric tons of plastic were produced worldwide, and the annual global production is projected to exceed 1.3 billion tons by 2060 if trends continue.
While Zenit ET cameras are not made of plastic, they are relevant to the topic of plastic production as they are a product of the former USSR, a major global oil producer and exporter. The cameras were manufactured by Vileiskiy Zavod Zenit (Vileiskiy factory Zenit) of BelOMO (Belorussian Optical and Mechanical Association) near Minsk, and by KMZ in the town of Krasnogorsk, Russia. Zenit cameras were exported to 74 countries in the 1960s and 1970s, contributing to a global market that drives plastic production.
