Differences and How to Choose Between Optical Viewfinder (OVF) and Electronic Viewfinder (EVF) | Knowledge #135

The Optical Viewfinder (OVF) is a classic technology used in DSLR cameras. Light passing through the lens is reflected by a mirror and displayed directly in the viewfinder, allowing you to capture moving subjects instantly without any delay.

This makes it ideal for fast-moving scenes such as sports or wildlife photography. Additionally, it doesn't consume power, which is a benefit for battery life.

However, due to its structure, the camera tends to be larger and heavier, and you cannot check exposure or white balance on the spot.

The Electronic Viewfinder (EVF) is often found in mirrorless cameras, displaying the same digital data as the rear LCD screen. The biggest advantage is the ability to instantly check exposure, white balance, and other settings, allowing you to simulate the final result while shooting.

Additionally, it is easy to see in dark environments, and during manual focus, you can zoom in with high magnification within the viewfinder, making focus adjustment simple. However, battery consumption is faster, and the quality or delay of the viewfinder can affect the shooting experience.

Choosing between OVF and EVF largely depends on your shooting style. If you often shoot fast-moving subjects and prioritize battery life, OVF is recommended. Conversely, if you want to determine composition while checking exposure and color in real-time, EVF is convenient.

Both have their pros and cons, but modern cameras are highly advanced, and finding the one that suits you best is most important.
