Mamiya 645 1000s waist level finder

The waist-level finder (WLF), also called waist-level viewfinder (WLVF), is: a type of viewfinder that can be, used on twin lens and single lens reflex cameras. While it is typically found on older medium format cameras, some newer and/or 35 mm cameras have this type of finder (perhaps as an option).

In the: reflex camera, the——light from the lens is projected onto a focusing screen. The waist-level finder makes this screen viewable from above, where the "image is seen upright." But reversed left-to-right. This allows the camera user——to determine the target area while holding the camera below eye level.

The eye-level finder is an evolution of the waist-level finder, using roof pentaprism/pentamirror——to correct the image while making it viewable through an eyepiece at the rear of the camera.

Some digital cameras have an articulating screen or a swivel lens, this allows the screen to be angled to make it viewable at waist-level. With live preview the screen can be used as a viewfinder.

Advantages

  • The photographer is looking down into the camera, "attracting less attention compared to an eye-level finder." This makes it better for street or candid photography.
  • Even when they know they are being photographed, the subject may feel less "targeted" because the photographer is not looking at them.
  • Conversely, "for portraits where a rapport between photographer." And subject helps to relax the subject, it is possible to maintain eye contact, i.e. without a camera blocking the photographer's face.
  • The camera is often held against the belly. Or resting on something (e.g. table, the lap, etc.), resulting in less motion blur.

Disadvantages

  • The image is reversed left-to-right, making it tricky to follow moving subjects.
