Range Finder
Some cameras allow the user to look directly through the lens of the camera to see the image being photographed. Other cameras have a window with a small lens through which the users views the scene.
Range finder: A camera focusing system that determines the distance between camera and subject.
Reciprocity law: It states that the exposure equals intensity multiplied by duration. This rule fails with very low or high intensities of light.
Range finder camera
A camera that uses a system of prisms and mirrors to bring an image into focus, even though the viewfinder (unlike an SLR) is separate from the lens. Also sometimes known as a lens-shutter or "point and shoot" camera.

RF - Range Finder - a type of camera viewfinder that uses one lens to frame your subject and another lens to capture the image. See "SLR" for the other type.
Electronic range finder can not be used with shifting or tilting.

I love to shoot with two fixed focal length lenses on two quiet range finder Leicas hanging around my neck, partially concealed under a vest or jacket.
Parallax problems-This occurs mainly with range finder and twin lens reflex cameras. The distance between the center of the lens and the viewfinder causes parallax. The closer the lens is focused to the subject, the more evident the parallax.
Two optical prisms capture the light rays coming from the opposite sides of the lens and divert it to the AF sensor, creating a simple range finder with a base identical to the lens' diameter.
(Single-lens Reflex) A camera that has one lens that is used for both composing the frame and capturing the image to memory, as opposed to Range Finder. The same as TTL.

method to set the f-stop to obtain the sharpest possible picture.
Mechanical method based on object space: estimate distances on the subject and use a DOF table. I feel this method is the less precise of the three unless you use laser range finders.
