Viewfinders often show lines to indicate the edge of the region which would be included in the photograph. The error varies with distance, being negligible for distant scenes, and very large for close-ups. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. A declining minority of point and shoot cameras use them. 1.2 Waist-level (reflecting) viewfindersīefore the development of microelectronics and electronic display devices, only optical viewfinders existed.ĭirect viewfinders are essentially miniature Galilean telescopes the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics.Prices of external viewfinders start just below the hundred Euros, electronic viewfinders from about two hundred Euros. Whether an external viewfinder is for you, will partly depend on how much it is worth to you and how often you want to use it. The electronic plug-in viewfinder of Panasonic (right) gives such a small picture, that you can no longer focus accurately manually. The optical LCD viewfinder (left) produces a larger image than an SLR or (in this case) a camera with built-in electronic viewfinder (center). Below is the relative magnification of a 3 viewfinders. The larger magnification you get with the help of a magnifier that you put on the screen works very nice. Because you can tilt an electronic viewfinder, it is sometimes possible to use an EVF as angle viewfinder. Using an additional viewfinder is useful when you need to work concentrated or when you are troubled by striking sunlight on your LCD screen. Unlike the micro-43 lenses, these electronic viewfinders can only be combined with its own brand of camera. Examples include the Olympus VF-2 or the Panasonic EVF 1 for micro-43 cameras. This type of viewfinder is only available for a limited number of cameras. An electronic viewfinder (EVF), which is placed in a special contact on top of your camera.In fact, this is also an optical viewfinder. A magnifier that you place over the LCD of your camera like a viewfinder.This type of viewfinder can basically be used on a variety of cameras used, provided the focal length of the lens on the camera matches that of the optical viewfinder. An optical viewfinder with a fixed focal length usually placed in the hot shoe on top of the camera.Three types of plug-in viewfinders are available: The combination of camera, lens and viewfinder is still much lighter than an SLR with lens. Using an LCD magnifier/viewfinder, the size of the camera substantially increases. Increase factor of 2x – 4x (dependent on brand).Characteristics of an external viewfinder The LCD viewfinder is also ideal for users of an SLR camera who make videos: because the mirror is flipped up during filming, you are dependent on the LCD screen to focus, like the users of a mirrorless camera. The LCD viewfinder is often used to take a picture (or view) with the LCD in bright sunlight. Using a plug-in viewfinder also improves the stability while focusing, because the camera is held closer to your body when focusing. Using an LCD viewfinder, you can, thanks to the built-in magnifier, focus the camera more accurately. But there are also systems with a different method of attachment. This external viewfinder is mounted on a metal magnetic strip that you first have to paste on your viewfinder. Is it something for you?Īn LCD viewfinder, as shown above, is a magnier clicked around the LCD screen of a camera. But with the advent of viewfinderless micro-system cameras and the introduction of Liveview on SLRs, there is a renewed need for external electronic and optical viewfinders on the market. Owners of SLR cameras do not need that additional viewfinder. If you still want to use a wide angle lens on a rangefinder camera, you buy an extra optical viewfinder for that, which you put on top of the camera. A built-in viewfinder is not optimal in this case. Due to parallax, you see something else through the viewfinder than on the picture when using a wide angle lens. LCD VF perfect viewfinder for a viewfinderless camera?Įarlier, they used a rangefinder camera (read: Leica M) only with a limited range of focal lengths.
