Answer 1

Here's an excellent article that explains how rangefinder cameras work (vs. SLR):

Answer 2

Rangefinder type cameras have a mechanical link between the lens, and a prism, or split image in the viewfinder. Rotating the lens moves the prism, or split image back and forth. when the image in the viewfinder is a single image its in focus in the camera. Not too popular today, but common in the past.

Answer 3

I have an old Leica 35mm from 1937. This is a range finder model, in fact it has two viewfinders, one for focusing and one for composition. Seems cumbersome but actually works well enough. When focusing, you see two images in the viewfinder, you have to rotate the lens until the two images become one, then you know you're in focus. Still works like a dream but only suitable for B/W because no lens coatings but the mechanics are pristine and the sound of the shutter blind moving across is like music.

Answer 4

Where with a single lens reflex camera, (SLR) you look through the actual lens, on a viewfinder type, you are looking through a separate type lens. (SLR is the best way.)
