3) Electronic Viewfinder (EVF)

When it comes to camera viewfinders, the electronic viewfinder (EVF) has gained significant popularity due to its technological advancements. An EVF works by using a digital display to replay the output from the camera’s image sensor.

This allows photographers to see a real-time preview of the image before it is captured. Let’s delve deeper into how an EVF works and explore its advantages and disadvantages.

3.1 How an Electronic Viewfinder Works

Unlike optical viewfinders that rely on a series of mirrors and prisms, an EVF operates by digitally reconstructing the image from the camera’s sensor. When you look through the viewfinder, the EVF displays a digital version of the scene, allowing you to see exactly what the image sensor sees.

The process begins with the camera’s image sensor capturing incoming light and converting it into a digital signal. This signal is then processed by the camera’s image processor, which converts it into a visual representation.

The processed image is then displayed on the digital screen within the viewfinder for the photographer to see. One of the key advantages of an EVF is that it provides a “What You See Is What You Get” (WYSIWYG) representation of the final image.

This means that any adjustments made to camera settings such as exposure, white balance, or ISO are immediately reflected in the viewfinder. As a result, photographers can accurately assess the final image before pressing the shutter, eliminating technical mistakes and improving the overall image quality.

3.2 Advantages of an Electronic Viewfinder

Using an electronic viewfinder comes with several advantages that can greatly enhance the photography experience. Firstly, the WYSIWYG representation provided by an EVF allows photographers to see the final image in real-time.
