The concept of mirrorless technology explained

Mirrorless technology is a relatively new innovation that has revolutionized the world of digital photography. To understand how mirrorless cameras work, let’s first delve into the concept of traditional DSLR cameras.

A DSLR (Digital Single-Lens Reflex) camera uses a mirror and a prism system to reflect light from the lens to the optical viewfinder. This mirror reflects the light entering the lens upward into the prism, which then redirects the light to the viewfinder, allowing the photographer to see the scene. When the shutter button is pressed, the mirror flips up, and the image sensor is exposed to capture the photo.

Mirrorless cameras, on the other hand, do not have a mirror mechanism. Instead, they utilize an electronic viewfinder (EVF) or the camera’s rear LCD screen to display the image captured by the image sensor. So how do mirrorless cameras achieve this?

Inside a mirrorless camera, light passes directly through the lens and onto the image sensor. The image sensor then records the light information to create the digital image. Since there is no mirror to flip up and redirect the light, the image sensor is always exposed to light, allowing the photographer to see a real-time preview of the final image through the EVF or LCD screen.

This direct light path in mirrorless cameras brings several advantages. Firstly, it allows for a more compact and lightweight camera body since the absence of a mirror mechanism eliminates the need for extra space. Mirrorless cameras are therefore more portable, making them ideal for travel and on-the-go photography.

Another advantage of mirrorless technology is the ability to provide a live preview of the final image. The electronic viewfinder (EVF) or LCD display can show real-time adjustments of exposure, white balance, and other settings, helping photographers see the exact result they will capture before taking the shot. This can be particularly useful for beginners who are learning about different camera settings.

It is important to note that the technology behind mirrorless cameras is rapidly evolving. Manufacturers are continuously improving autofocus performance, image stabilization, and other features to compete with DSLRs. The gap between the two types of cameras is narrowing, with mirrorless cameras now offering comparable image quality and performance.
