The one shown here is a 50mm Jupiter-8 lens. Many FEDs come with Industar lenses. On this lens, the aperture is set on the front and focusing is done with a focusing ring. The rangefinder is coupled to the lens. The field of view in the viewfinder is that of a 5 cm lens.
Early in World War II, the range to the target was measured by optical rangefinders. Though some night operations were conducted using searchlights and star shells, in general optical rangefinders were limited to daytime operation. [10] During the latter part of World War II, radar was used to determine the range to the target.
Eyepiece image of a naval rangefinder, showing the displaced image when not yet adjusted for range. The coincidence rangefinder uses a single eyepiece. Light from the target enters the rangefinder through two windows located at either end of the instrument. At either side the incident beam is reflected to the center of the optical bar by a ...
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
A stereoscopic rangefinder or stereoscopic telemeter [1] is an optical device that measures distance from the observer to a target, using the observer's capability of binocular vision. It looks similar to a coincidence rangefinder , which uses different principles and has only one eyepiece.
The Canon Canonet G-III QL17 is a coupled-rangefinder, leaf-shuttered, fixed-focal-length 35 mm camera first manufactured by Canon between 1972 and 1982. It features fully shutter-priority automatic exposure and fully manual shooting modes. The Canonet G-III is the third generation of Canonet, following the original Canonet and the New Canonet.
Rangefinder Camera Mechanism. Some cameras do not have a beam splitter; these cameras instead have a separate viewfinder.The first rangefinders, sometimes called "telemeters", appeared in the twentieth century; the first rangefinder camera to be marketed was the 3A Kodak Autographic Special of 1916; the rangefinder was coupled.
The Zorki 10 is a modern-style 35mm rangefinder camera with a selenium light meter and shutter priority automatic exposure introduced in 1964. The Zorki 11 is a cheaper model without the rangefinder, and the Zorki 12 is a variant using Agfa's Rapid film [de; ru] cartridges. All three variants have fixed (non-interchangeable) lenses.
