Electronic viewfinder vs optical viewfinder manual#

Focus peaking to aid with manual focusing. Things like the histogram so you can achieve the optimum exposure. However, an EVF can display a much larger amount of information. At the bottom of the viewfinder they can display useful information regarding the exposure settings, battery life etc. Optical viewfinders often have a few overlays, for example to show the autofocus points and grid lines to help composing. They are also subject to parallax error if you are photographing something near the camera. Similar to a rangefinder viewfinder, these often show frame lines to indicate a focal length and let you view what is going on outside of the frame.Ġ80418_viewfinder by all martn on flickr (licensed CC-BY-ND)īut accessory optical viewfinders are not linked to the lens, so don't show focus, nor can you preview depth of field. Like accessory EVFs, these will normally be mounted in the camera's hot-shoe. However, you can purchase accessory optical viewfinders. Through the lens optical viewfinders are not generally interchangeable. It also doesn't make a lot of sense to use an older EVF with a new camera model as EVF technology will have improved as well and a new EVF would give a better experience.

However, technology moves fast and there are sometimes changes that mean old EVFs don't work with new camera models and new EVFs don't work with old models.

Similarly, you should be able to upgrade to a new accessory EVF, and use it on your current camera. In theory, this should also mean that you can buy an accessory EVF once, and then continue using it on your next camera when you upgrade. This allows you to have a smaller body with no viewfinder (use the LCD screen on the back), or you can add the EVF when you need it. Some cameras come with EVFs built in, but other models allow you to purchase an EVF as an accessory. This article will mainly focus on the differences between through the lens (TTL) optical viewfinders and electronic viewfinders, as these are what the large majority of cameras use. They have the disadvantage that they don't show the view through the lens, but the advantage is that you can see what is going on outside of the frame and plan your shot accordingly. These tend to be used on rangefinder cameras. There are also other types of optical viewfinder that use a separate viewfinder window, instead of showing the view through the lens.
