There are different types of viewfinders, each with its own advantages and disadvantages. In this blog post, we will explore the main types of viewfinders and how to use them effectively.
Optical viewfinder (OVF)
An optical viewfinder is a simple and direct way of seeing what the camera lens sees. It uses a system of mirrors and prisms to reflect the light from the lens to the eye. Optical viewfinders are common in DSLR cameras and some compact cameras.
The main advantage of an optical viewfinder is that it shows a bright and clear image, without any lag or delay. It also does not consume any battery power, unlike electronic viewfinders or LCD screens. Optical viewfinders are useful for shooting in low-light conditions, fast-moving subjects, or when you need to conserve battery life.
The main disadvantage of an optical viewfinder is that it does not show the exact image that will be captured by the sensor. It may have a different magnification, coverage, or aspect ratio than the sensor. It also does not show any information about the exposure, white balance, or other settings that affect the final image. Optical viewfinders are limited by the physical size and shape of the camera body, and may not be compatible with some lenses or accessories.
Electronic viewfinder (EVF)
An electronic viewfinder is a device that uses a small LCD screen to display what the camera sensor sees. It simulates the image that will be captured by the sensor, and can show various information and settings on the screen. Electronic viewfinders are common in mirrorless cameras and some compact cameras.
The main advantage of an electronic viewfinder is that it shows an accurate and realistic image, with no parallax error or cropping. It also allows you to preview the effects of exposure, white balance, filters, or other settings on the image. Electronic viewfinders are useful for shooting in bright conditions, where the LCD screen may be hard to see or use. They also offer more flexibility and customization than optical viewfinders.
The main disadvantage of an electronic viewfinder is that it consumes battery power, and may have a lower resolution, contrast, or color accuracy than the sensor. It also may have some lag or delay, especially in low-light conditions or when panning or zooming. Electronic viewfinders are dependent on the quality and size of the LCD screen, and may not be as comfortable or natural as optical viewfinders.
LCD screen
An LCD screen is a device that uses a large LCD panel to display what the camera sensor sees. It can also show various information and settings on the screen. LCD screens are common in most digital cameras, especially point-and-shoot cameras and smartphones.
The main advantage of an LCD screen is that it shows a large and detailed image, with no parallax error or cropping. It also allows you to preview the effects of exposure, white balance, filters, or other settings on the image. LCD screens are useful for shooting from different angles or perspectives, where a viewfinder may be hard to use or access. They also offer more interactivity and functionality than viewfinders.
The main disadvantage of an LCD screen is that it consumes battery power, and may have a lower resolution, contrast, or color accuracy than the sensor. It also may have some lag or delay, especially in low-light conditions or when panning or zooming. LCD screens are hard to see or use in bright conditions, where they may reflect glare or sunlight. They also may not be as stable or ergonomic as viewfinders.
How to choose and use a viewfinder
Choosing a viewfinder depends on your personal preference, shooting style, and camera type. Some cameras may have more than one type of viewfinder available, while others may have none at all. Here are some tips on how to choose and use a viewfinder effectively:
- Consider your subject matter and lighting conditions. If you are shooting fast-moving subjects or in low-light situations, you may prefer an optical viewfinder for its speed and clarity. If you are shooting in bright conditions or need to preview your settings, you may prefer an electronic viewfinder or an LCD screen for their accuracy and realism.
- Consider your camera size and weight. If you are using a large and heavy camera, you may prefer an optical viewfinder for its stability and comfort. If you are using a small and light camera, you may prefer an electronic viewfinder or an LCD screen for their flexibility and convenience.
- Consider your shooting angle and position. If you are shooting from eye level or close to your body, you may prefer a viewfinder for its natural and immersive feel. If you are shooting from a high or low angle, or at arm's length, you may prefer an LCD screen for its versatility and ease of use.
- Consider your creative vision and style. If you are shooting for a realistic and accurate image, you may prefer an electronic viewfinder or an LCD screen for their preview and feedback. If you are shooting for a creative and artistic image, you may prefer an optical viewfinder for its simplicity and spontaneity.
A viewfinder is a powerful tool that can help you capture better photos. By understanding the different types of viewfinders and how to use them effectively, you can enhance your photography skills and enjoy the process more. Happy shooting!
