	Single-lens reflex camera
		The major advantage of single lens reflex cameras is the ability to determine what parts of the image are in focus by looking through the taking lens itself.
		The single-lens reflex camera, more commonly known by the abbreviation SLR, uses a mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen.
		The SLR cameras also offer the ability for the photographer to quickly and simply change the lens, thus making them versatile.

	Digital single-lens reflex camera - Wikipedia, the free encyclopedia
		A digital single-lens reflex camera (Digital SLR or DSLR) is a digital camera that operates on the same optical and mechanical principles as a modern electronic autofocus 35mm film single-lens reflex camera.
		The principal advantage of the SLR film camera over non-SLR film cameras is the ability to see the image exactly as it would appear on film, whatever the lens used, and without parallax errors due to a viewfinder offset from the lens.
		In the digital era zoom lens design is sufficiently advanced to almost eliminate the market for non-SLR cameras with interchangeable lenses, so lens interchangability is, in practice, restricted to the digital SLR.

	Photometric apparatus for single lens reflex camera - Patent 4064517
		In a conventional single lens reflex camera, the light which is transmitted through a photographic optical system is made to be directly incident on a photoelectric transducer element which is interposed on a light path at a position nearer an object being photographed than a film.
		Specifically, a single lens reflex camera 202 having a movable reflecting mirror 201 includes a film 203 in its rear part which is urged against and retained by a pressure plate 204.
		When the camera is directed to an object being photographed, the second transducer element 410 receives light from an object being photographed as reflected by the reflecting mirror 405, thereby deflecting the pointer 409a of the galvanometer depending upon the brightness of the object being photographed.

		A lens hood should always be used on all lenses and cameras because it reduces flare and distortion and results in sharper, crisper photographs.
		A 50-mm lens is usually the lens sold with the camera.
		A normal lens for a 35-mm camera is 50mm in focal length.

		There are single lens reflex digital cameras very similar to SLR film cameras where you see an optical image through the same lens that will take the picture.
		A common type of camera is a 35mm single lens reflex camera.
		To focus a SLR camera you turn a ring on the lens until the subject is clear.

	Biography Johan Steenbergen - The Exakta single-lens mirror-reflex camera
		film in a single-lens reflex camera was at first received with suspicion; it was believed to be a technical impossibility.
		The Kine-Exakta, as the first miniature ('35 mm.') single-lens reflex, was a milestone in photography technology.
		All post-war single-lens cameras were developed from this design.

	Graflex RB Series B 2.25x3.25 SLR Camera
		The viewing hood and mirror (hence, single lens reflex) design provided a convenient right side up image of the subject (reversed left for right).
		As with many cameras that aren't rare enough to be really collectible, but too old to be good users, you can often pick one of these up for your display collection for only $100 and up.
		I'm sorry to say that this info does not match the camera in the photos, which is quite obviously an RB Series B 2-1/4" X 3-1/4" Graflex, made from 1923-1951, and common as dirt (well, nearly).

	The Single-Lens Reflex Camera
		The “Reflex” part means that the camera is equipped to let you see the same image that will be recorded on the film when the shutter opens -- the optical system that lets you do that makes the camera seem more optically complicated than it really is.
		The one shown is a sophisticated compound achromatic lens, designed to produce a very flat focal plane at the film, but you can think of it as just a thin converging lens with a focal length of about two inches.
		An adjustment lets you move the lens closer or further from the film-- basically to adjust the image distance to match the object distance for the subject you want to photograph.

	PSA Journal: Nikon N6006 - autofocus single lens reflex camera - Evaluation
		With a body of high impact plastic, the lens mount retains the traditional Nikon F stainless steel bayonet lens mount that enables use of almost all Nikon lenses in addition to the present autofocus (AF) lenses.
		Also, it uses an expensive lithium battery, which is unsatisfactory for anyone using the camera on a regular basis (lithiums are great for casual users, as they have a long storage life, and can sit in the camera for extended periods of time, keeping their charge).
		Nikon N6006: (Illustration 1) Nikon continues its practice of designating autofocus cameras in the "N" series, and as the "6006" indicates, this camera is mid-range between the N4004s/n5005 and the N8008s.

	What is a SLR (Single Lens Reflex) Camera?
		Single lens reflex cameras allow the photographer to see the precise focus, color, framing, and brightness that will be recorded on film, because the viewfinder looks through the lens.
		SLR cameras eliminate parallax error that is inevitable with cameras that have different paths for the lens and the viewfinder.
		A prism, flip-up mirror, and interchangeable lens makes an SLR camera extremely accurate.

	'+alt+'
		Sometimes manufacturers omit the camera lens altogether by bringing the normally parallel rays emerging from the photo eyepiece to convergence in the camera’s image plane by lifting the eyepiece out of its sleeve by a certain distance and sometimes that distance is already added to the eyepiece’s shoulder which then should be called a projective.
		If the eyepiece were of 10x and the camera lens of 0.32x power, the product of the two, 3.2 would be the magnification of the intermediate image in the plane of the chip.
		To capture the same field with a DSLR as with a 35mm SLR, either the magnification of the photo eyepiece or the focal length of the camera lens must be smaller by a factor of 1.6x.

		The camera elevation control is used to center the camera lens vertically in front of the pupil.
		The camera must be held on the same horizontal level as the center of the face because undesired psychological effects and skewed facial geometry may result if the camera is directed at the patient from either a superior or an inferior position.
		By laterally sliding the camera so that its point of view moves from one side of the corneal apex to the other, the same point in the fundus may be observed from 2 points of view.

	Howstuffworks "How Cameras Work"
		A still film camera is made of three basic elements: an optical element (the lens), a chemical element (the film) and a mechanical element (the camera body itself).
		This is a camera where the photographer sees exactly the same image that is exposed to the film and can adjust everything by turning dials and clicking buttons.

		This means that you have a reflex model camera but you cannot remove the lens that comes with the camera.
		Eventually, amateur cameras popped up that used 35mm film, but lenses were still inexpensive and viewfinders were only an approximation of what would be captured on the film.
		Hence, even the cheapest digital point-and-shoot model shows you the view through the camera's lens.

	Early History of Single Lens Reflex (SLR) camera
		After World-War-II these Single Lens Reflex cameras- SLR- were smiled by estabilshed photographs because they are quite ugly, odd, heavy and slowly.compared to fast LEICA or CONTAX with their elegant rangefinders.
		The West-German answer to the Japanese focal plane shutter cameras is the CONTAREX - 1958 showed at Photokina - excellently finished, but hevyweight (910g without lens) and far too expensive and complicated.
		Ugly selenium meter (bulls-eye) coupled both to shutter speed and aperture dial (which is part of the camera, not the lens).
