Overview of Electronic Viewfinders
Photography has evolved rapidly in recent years, and a crucial part of this evolution has been the conception of electronic viewfinders. So, what are they all about? Let’s get into it.
Definition of electronic viewfinder
An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is projected electronically onto a miniature display. The viewfinder is the eyepiece on a camera that you look through to frame your shot. Up until the advent of the EVF, most cameras used optical viewfinders.
Basic functioning of electronic viewfinder
The EVF works by capturing the same image that hits the image sensor of the camera. It then digitally projects this image onto a small electronic screen which you see when you look into the viewfinder. In essence, it is like looking at a small television screen.
Types of electronic viewfinders
There are two basic types of electronic viewfinders: LCD and OLED. The LCD (Liquid Crystal Display) viewfinders are the more common type and quite similar to the displays used on the back of most digital cameras. OLED (Organic Light-Emitting Diode) viewfinders, are newer and provide better color accuracy, contrast, and energy efficiency.
Difference Between Electronic and Optical Viewfinders
Understanding the difference between the different types of viewfinders can greatly enhance your understanding of photography gear and help you choose the right camera that suits your needs.
Overview of optical viewfinders
Optical viewfinders have been a mainstay of photography for decades. They function using a system of mirrors and prisms that reflect the image captured by the lens straight to your eye. This means that when you look through an optical viewfinder, you are seeing a truly “live” view of your subject with no digital processing.
Comparing resolution
When comparing the resolution between electronic and optical viewfinders, electronic viewfinders do lag behind. Although high-resolution EVFs are growing more common, they still can’t match the crystal-clear image provided by an optical viewfinder.
Comparing light performance
In low-light situations, electronic viewfinders have an advantage. They digitally enhance the view, making it easier to see your subject. On the other hand, optical viewfinders can only display what the lens gathers, making them less effective in low-light conditions.
Assessing accuracy
In terms of accuracy, an electronic viewfinder gives you a preview of exactly what the camera sensor sees. This is supremely helpful when it comes to adjusting settings and framing, allowing you to see changes in real-time. An optical viewfinder shows you what the lens sees, which can sometimes be different from the final image due to lens distortion and parallax issues.
The Role of Electronic Viewfinders in Modern Photography
Electronic viewfinders have made a significant impact on modern photography and introduced a host of new features.
Critical for mirrorless cameras
Since mirrorless cameras lack the mirror mechanism that directs light to the viewfinder in DSLRs, they inherently require electronic viewfinders. The EVF in a mirrorless camera provides an accurate preview of what the image sensor sees.
Usefulness in low-light conditions
One of the biggest challenges in photography is shooting in low-light conditions. Electronic viewfinders excel in these situations as they digitally boost the image, making the subject easier to see compared to optical viewfinders.
Use in video recording
Because of their digital nature, electronic viewfinders excel in the field of video recording, showing a real-time readout of your capture and even allowing for playback within the viewfinder itself.
Enhanced creative control
Electronic viewfinders offer several tools not available with optical viewfinders, like interactive histograms, focus peaking, highlighting overexposed areas, and real-time exposure adjustments; all of which give photographers an enhanced level of creative control.
Benefits of Electronic Viewfinders
Ever since their inception, electronic viewfinders have constantly expanded their repertoire of benefits that cater to photographers at all levels.
Real-time exposure preview
Electronic viewfinders revolutionized photography by providing a real-time exposure preview, allowing you to see how adjustments in settings will impact the photo before you take it.
Electronic zoom assist
Electronic viewfinders offer zoom capabilities not present in optical viewfinders. This feature is especially useful for manual focus, whereby you can zoom in on your subject to make sure your focus is spot-on.
Facilitating manual focus
EVFs make manual focusing easier. Features such as focus peaking, which highlights the area of the image that is in sharp focus, are invaluable for nailing manual focus.
Histogram display
Many electronic viewfinders will display a real-time histogram, allowing you to better judge exposure levels and adjust accordingly.
Zebra patterning for exposure enhancements
Another helpful EVF feature is ‘zebra patterning’, which alerts you to areas of your frame that are seriously overexposed by overlaying a striped pattern onto those regions.

Limitations of Electronic Viewfinders
While EVFs pack numerous features, they also come with certain downsides that are worth considering.
Battery consumption
The biggest downside to electronic viewfinders is that they consume a lot more battery power than optical viewfinders. This can be problematic if you’re shooting for extended periods away from a power source.
Display lag
Certain electronic viewfinders cause a slight delay between what happens in reality and when it appears in the viewfinder. This lag can cause issues, especially when shooting fast-moving subjects.
Lower resolution compared to optical viewfinders
Despite improvements, EVFs still can’t match the resolution offered by optical viewfinders, making the viewing experience less sharp and clear.
How Electronic Viewfinders Influence Photography Techniques
Electronic viewfinders have introduced new photography techniques and redefined some of the existing ones.
Influencing composition
The ‘what you see is what you get’ nature of EVFs can have a positive influence on composition, allowing you to accurately frame your shot in real-time as you adjust camera settings.
Shallow depth of field
The ability to zoom in and nail focus with an electronic viewfinder, allows for precise control over depth of field, meaning you can create stunning bokeh backgrounds with greater ease.
Silent shooting, “What you see is what you get” principle
Electronic viewfinders embed the ‘what you see is what you get’ principle into your workflow, where the live preview accurately represents the final image. This, combined with the ability for silent shooting in some mirrorless cameras, makes for discreet photography, particularly useful in situations like wildlife photography.

Electronic Viewfinders in Different Types of Cameras
While electronic viewfinders have found a sure-footed place in mirrorless cameras, they have made their way into various other types of cameras too.
Compact digital cameras
In compact digital cameras, an EVF can help save battery life as you don’t always have to use the larger rear screen.
Bridge cameras
Bridge cameras, which straddle the line between point-and-shoots and DSLRs, will also often feature an electronic viewfinder. EVFs in these cameras give users a more ‘DSLR-like’ experience.
Mirrorless cameras
The EVF is a critical component of mirrorless cameras as there’s no optical path from the lens to the viewfinder. Here, the EVF provides a live display of the image on the sensor.
Digital single-lens reflex cameras
While most DSLRs use optical viewfinders, some models feature a hybrid system incorporating aspects of both optical and electronic viewfinders, enhancing capabilities such as live-view and video recording.
