Also it’s just a pain to be pressing a button whenever you want to see a depth of field preview. DSLRs do have a “depth of field” preview button which will close down the aperture to whatever you have it set to – the problem is that if you’re shooting at smaller apertures the depth of field preview button will make things look unrealistically dark through the viewfinder (since the small aperture will greatly reduce the amount of light going through to the optical viewfinder. With most optical viewfinders you’re looking through the optical viewfinder with the lens aperture set wide open – which doesn’t give you an idea of what the actual depth of field will be in the image when you press the shutter release. Just like with exposure you can get a preview of what your depth of field will be with an EVF.
Having a realtime exposure preview will help you to dial in the exact exposure you want without constant chimping (like you might do with a DSLR with an optical viewfinder). With an electronic viewfinder you get a realtime preview of what your exposure will be – meaning the brightness of your photo will look like what you see through the EVF. Here are 7 things you need to know about electronic viewfinders: It’s really neat actually!īut with an electronic viewfinder (EVF), you’re actually just looking at a tiny screen (usually LCD or OLED). This may not seem like a significant difference, but having a camera with an EVF can make it a lot easier for you to learn photography. When you look through an optical viewfinder you’re actually looking through the lens of the camera (the light is bouncing off a mirror and flipped through a prism).
Most DSLR cameras have what are known as optical viewfinders. A viewfinder is a part of the camera that you look through in order to frame your photo.
