One is the Olympus OM-4T film camera, which has a remarkably generous and direct viewfinder for such a small camera. They're from different eras, so maybe I can be excused for mentioning them both. If some company was going to build your perfect camera, at your direction, what kind of viewfinder would you tell them to make?Īs I think about this question, two cameras come to mind. The one seems as broad as the Grand Canyon, the other like peering down a tunnel or through a keyhole. Larger cameras tend to have larger VFs-comparing the view through a medium-format DSLR to the one through a consumer APS-C with a mirror-box is instructive. The Leica SL's feature a super-high-quality screen, which nicely echoes the original Leitz SL's, some of which had microprisms over their entire field. How does the camera show the operator what it's about to take a picture of? It's a technical problem, of course, but it's also integral to how the photographer interacts with the visual world, and and how she relates to the camera as a tool.ĭo you like an OVF or EVF? TTL or not? Looking down, sideways, or remotely? Several Fujis can be switched at will from optical to EVF, an exotic but useful feature. A history of camera viewfinders would be astonishingly varied. "Finding the view" is one of the basic functions of a camera as a device, and has been since the beginning. Now that you know how things works internally, you will make a more informed decision when buying your next camera.Of all the viewfinders in all the cameras you've ever used, which would you say is your favorite? Besides, on a DSLR, the battery lasts longer thanks also to the optical viewfinder not consuming power. But on the other side, DSLR cameras benefit from a real live view with no time delay. Access to these settings while looking through the viewfinder makes shooting easier.įor this reason, mirrorless cameras have made DSLRs look old in this regard. It’s useful to see info such as the histogram, focus peaking, and image playback. Holding the camera up to the eye has certain advantages. Thanks to the brightness of the electronic viewfinder, you can see even in dark conditions. When looking through an EVF, you’ll see much more information. The EVF is in mirrorless cameras and consumes battery power, unlike optical viewfinders.īoth optical and electronic viewfinders have their sets of advantages and downsides. Before hitting the sensor, it’s processed and displayed on the viewfinder LCD as a digital image. In the Electronic or Digital Viewfinder ( EVF), the light passes through the lens.The picture you see through this viewfinder tends to be sharp and bright since it’s the same image seen by the lens. The light passes through the lens (TTL), hits a mirror that reflects it into the viewfinder via a pentaprism. The Optical Viewfinder (OVF) is built-in in DSLR cameras.They have optical or electronic viewfinders. The downside was that it created a parallax effect with subjects too close to the camera. In old rangefinder cameras, the viewfinder and the lens were separate from each other. Older systems could have the image turned the other way around or flipped. They are less bright than pentaprisms.Ĭuriosity: pentaprisms are probably the reason why single lens reflex (SLR) cameras have been a success. The pentamirror as the name suggests uses a mirror to reflect the light to the viewfinder. Full-frame and professional DSLRs feature a pentaprism, while APS-C cameras have a pentamirror. When the light passes through the lens a mirror bounces it to a prism that directs it to the viewfinder. You can watch this video if you want to learn how to adjust the diopter. It shows focus points, the light meter, exposure information, shutter speed, aperture, and ISO, among other settings.ĭiopter: shooters using correction glasses can use the diopter to adjust the focus and getting a sharp image on the small screen. The viewfinder displays significant camera settings. With fast-moving subjects, it helps the photographer frame images accurately. It’s a useful tool, mainly when shooting action photography. The viewfinder is a tiny rectangular screen built into almost all modern DSLR and mirrorless cameras.
