An optical device that’s either built into older cameras or added as an attachment that is used to work out the subject distance by comparing two viewpoints. You see a double image and adjust the lenses until the images form one which gives a distance reading that can then be transferred to the focusing ring.
This is the eye of the camera and is used to capture the image it sees onto the camera's light sensitive film, or CCD in digital camera. The size of lens is measured and indicated as a focal length. Cameras come with either a fixed lens or zoom lens with a range of focal lengths (see lens range) and on some SLR and rangefinder cameras the lens detaches so others can be attached to increase versatility. With a detachable lens camera it's often possible to buy just the body with a lens of your choice.The amount of light passing through the lens is controlled by an aperture, which is often quoted with its maximum aperture setting.Buying adviceSLRs: If you intend buying a specific lens in the future make sure that it's available in the same mount as the camera you are considering or own. Also if you're upgrading cameras, buy one with the same lens fitting or one that can be adapted to save the cost of replacing all the lenses you own.Digital and compact cameras: A fixed lens camera can often be much smaller so could be selected if you need to travel light. It's also less expensive if your budget is tight. It's better, though, to choose a camera with a zoom if you can afford to, rather than using a digital zoom or cropping the picture later. Go for one with a wider angle zoom if most of your pictures will be landscapes, interiors or family group shots.Choose a version with a longer telephoto setting if you want to shoot long distance subjects, portraits and wildlife.
This is what you look through to help point the camera in the right direction when taking a photo. SLR cameras have accurate through the lens viewing so what you see is what the lens sees. Compact, rangefinder and digital cameras have a separate viewfinder that is often less accurate at close range. Some cameras have an adjustment to change the eyepiece to suit your vision. Some have an accessory slot where a small correction lens can be attached.
