What Is a Digital Camera Viewfinder?

You may have heard of diopter, but it really isn’t.

You may have heard of a camera viewfinder called a diopter, but that’s not the case. A digital camera viewfinder is a viewing mechanism on the back of a DSLR (single-lens digital reflex) camera that allows the photographer to see the image to be captured. But there’s so much more to a camera viewfinder. There are different types and different mechanisms. Here’s what you need to know about the different sights.

What is the viewfinder?

The digital camera viewfinder is the part of the camera used to frame and adjust a photo. It is usually located on the back of the camera and can be an optical viewfinder or a digital or electronic viewfinder (EVF).

  • Optical viewfinder: The optical viewfinder is usually found in DSLR cameras. You will know it as the eyepiece behind the camera, usually upwards. It is an imaging mechanism that uses a method of reflection to show the photographer an image of the scene through the camera lens. Optical viewfinders can also display digital information in the viewing area about camera settings or shooting information about the scene the lens is focusing on. And the optical sights perform well in bright and low-light conditions.
  • Digital viewfinder: These may also be called electronic viewfinders (EVF) because the digital viewfinder displays an enhanced digital image of the image passing through the camera lens. This means that the image you see through the digital viewfinder may not be exactly the image captured by the lens. Still, digital viewfinders have some advantages. For example, a digital viewfinder can display a more accurate representation of the lighting conditions of the scene in focus.

Although usually included in the category of digital viewfinders, there is another type of viewfinder: the screen viewfinder. This is the screen on the back of most DSLR cameras where photographers can change settings, scroll through captured images, and in some cases make minor image edits or corrections. . Usually around two to two and a half square inches, this screen can also be used to frame a scene and focus the camera.

And in some cases, the viewfinder screen is a better option than the optical or digital viewfinder built into the camera body. For example, if you’re shooting in a place where it’s hard to hold the camera to your face, the viewfinder screen can help you focus better, especially if it’s an articulating screen that can move from left to right as well as up and down.

How the viewfinder works

How a sight works is determined by the type of sight you are using. The optical viewfinder uses a pentaprism or pentamirror to project the image moving from the camera lens to the viewfinder. If the optical viewfinder uses a pentaprism, the image is projected through the prism. This is how high-end DSLR camera viewfinders usually work.

Low-end and entry-level DSLR cameras typically use the pentamirror viewfinder system, in which the image passing through the lens is projected onto the viewfinder using a series of mirrors. These mirrors are usually plastic and can be heard moving when the camera’s shutter button is pressed. This is because pentamirror systems have a mirror located directly in front of the image sensor and must be turned up and out to capture the image.

Both types of optical viewfinders work great for capturing sharp images, as long as the diopter, the lens on the front of the viewfinder, is adjusted to match the photographer’s sight.

Electronic viewfinders work the same way, but the image reflected in the viewfinder is not the image passing through the camera lens. Instead, it’s a digital representation of that image.

The disadvantage of electronic viewfinders is that they consume battery power, which shortens the shooting time, and if the resolution of the digital viewfinder does not match the resolution of the camera, you risk not to see a precise image. the scene you are trying to photograph.

As mirrorless cameras become more popular, digital viewfinders are becoming more common, since mirrorless cameras do not have optical viewfinders.

What is the best optical or digital viewfinder?

It’s common for a beginning photographer to wonder whether it’s better to use an optical or digital viewfinder. The problem is that everyone is better in certain situations.

For example, an optical viewfinder is always better in very bright situations because it helps reduce the amount of glare your eye sees so you can better see the image passing through your lens.

However, if you are shooting in low light conditions, the digital viewfinder can better accurately represent the amount of light passing through your lens.

In general, most professional photographers prefer the optical viewfinder because in most cases it provides the most accurate representation of the image passing through the lens. The optical viewfinder also provides a way to prop up the camera while shooting, as it needs to be brought in front of your face for you to look through the viewfinder. This, combined with keeping your elbows close to your body, can help stabilize the camera and reduce the amount of jerking that can occur when trying to hold the camera away from your body.

Optical Viewfinder: An optical viewfinder is most often found on DSLR cameras. You’ll know it as the eye piece on the back of the camera, usually toward the top. This is a viewing mechanism that uses a method of reflection to show the photographer a view of the scene through the lens of the camera. Optical viewfinders may also show some digital information in the viewing field about the the camera settings or shooting information about the scene the lens is focused on. And optical viewfiders work well in both bright and low light conditions.
Digital Viewfinder: These may also be called electronic viewfinders (EVFs) because a digital viewfinder shows an enhanced digital image of the image traveling through the camera lens. This means the image you see through a digital viewfinder may not be exactly the view that the lens is capturing. Digital viewfinders do have some advantages, though. For example, a digital viewfinder may show a more accurate representation of the lighting conditions for the scene that is in focus.

There’s also another type of viewfinder, though it is often lumped into the digital viewfinder category: the viewfinder screen. This is the screen on the back of most DSLR cameras where photographers can change settings, scroll through captured images, and in some cases, make some minor changes or corrections to the image. This screen, which is usually about two to two and a half inches square, can also be used to frame a scene and focus the camera.

And, in some cases, the viewfinder screen is a better option than the optical or digital viewfinder located on the body of the camera. For example, if you’re shooting in a place where it’s awkward to hold the camera to your face, the viewfinder screen may help you focus better, especially if it’s an articulating screen that can move left and right as well as up and down.

Both types of optical viewfinders work very well for capturing accurate images as long as the diopter, which is the lens in front of viewfinder, is adjusted properly for the photographer’s vision.

Electronic viewfinders work in a similar fashion, except the image that is reflected into the viewfinder is not the image that travels through the camera lens. Instead, it is a digital representation of that image.

The downfall of electronic viewfinders is that they consume battery power, which shortens the amount of time that you can shoot, and if the resolution of the digital viewfinder doesn’t match the resolution of the camera, you might not be seeing an accurate image of the scene you are trying to photograph.
