Single Lens Reflex Camera

When Was the Single Lens Reflex Camera Invented?

The Single Lens Reflex camera, commonly known as SLR, revolutionized photography by allowing photographers to see exactly what they were capturing. Prior to the invention of SLR, photographers had to use view cameras or twin lens reflex cameras. In this article, we will take a closer look at the history of SLR cameras and how they evolved over time.

The First Concepts of Camera Obscura

The concept of camera obscura was first developed in ancient times, but it was not until 1021 that an ancient Chinese philosopher named Mozi recorded the first concept of camera obscura. The camera obscura was essentially a dark box or room with a small hole in one of the walls that would allow light to pass through and create an image of the outside world on the opposite wall. However, this was not a practical method for capturing images.

The Invention of Camera and Its Evolution

The first true camera was invented by Joseph Nicephore Niepce in 1816. His camera used a metal plate coated with bitumen that could capture images when exposed to light. Louis Daguerre later improved on Niepce's invention and introduced the daguerreotype in 1839, which was the first commercial camera. In the following years, many inventors like George Eastman added new features to the camera, such as roll film and self-contained darkrooms.

The Development of SLR Technology

The first Single Lens Reflex camera was invented by Thomas Sutton in 1861. His camera used a mirror to reflect the image through a ground-glass plate in the back, allowing photographers to see exactly what they were capturing. However, Sutton's camera was never commercially produced. It was not until the 1930s that the first commercially successful SLR camera was introduced by Ihagee Kamerawerk Steenbergen & Co in Germany.

After the initial success of the Ihagee Exakta, many companies like Canon, Nikon, and Pentax introduced their own SLR cameras with different features and advancements. In the 1950s, the first SLR camera with the ability to change lenses was introduced by Pentax. In the following years, SLR cameras became more advanced with features like auto-focus, motorized film advance, and built-in light meters.

Today, SLR cameras have largely been replaced by digital cameras, but they remain popular among professional photographers and enthusiasts. Many digital cameras still use SLR technology, but instead of using film, they use digital sensors to capture images.


The invention of the Single Lens Reflex camera revolutionized photography by allowing photographers to see exactly what they were capturing.

With the ability to detach lenses, photographers can adapt to different shooting situations and experiment with different focal lengths and angles. SLRs allow for a greater amount of creative control over the final image, which is highly desirable for professional photographers and photography enthusiasts. It also offers the opportunity to change lenses during a shoot to capture different perspectives of the same scene. This flexibility makes SLRs suitable for a wide range of photography subjects such as landscapes, portraits, and sports photography.

In addition, SLRs have manual control over aperture, shutter speed and ISO, which offers the photographer greater creative control over the final image. The manual settings are ideal for photographers who desire complete control over their images and prefer to experiment with different settings.

High Speed and Low Light Performance

The high-speed performance of SLRs is another one of their major advantages. They are capable of capturing images with better accuracy, even in fast-moving situations. This is due to their rapidly autofocus and continuous shooting modes. SLRs are particularly useful for capturing action shots such as sports events, wildlife, and dance performances. Moreover, the high-speed performance ensures that the photographer does not miss a crucial moment.

SLRs are also capable of delivering high-quality images in low light conditions. Their wide aperture lenses and high-performance image stabilization system produce sharper images with less noise and blur, even in the absence of a flash. This is particularly useful when shooting at night, in dimly lit spaces, or when capturing fast-moving subjects.

In conclusion, the advantages of the single lens reflex camera include high-quality images, flexibility, and high-speed and low light performance. The ability to detach lenses and manually control the camera settings, makes SLRs highly desirable for professional photographers and photography enthusiasts alike.
