	Rangefinder camera -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-10-07)
		A rangefinder camera is one with a (A measuring instrument (acoustic or optical or electronic) for finding the distance of an object) rangefinder that allows the photographer to judge the focusing distance.
		Most recent designs are coupled rangefinders - that is, the focus is adjusted both in the rangefinder and in the lens by the same control, usually a ring on the lens.
		In older designs the rangefinder is separate from the (Optical device that helps a user to find the target of interest) viewfinder; in most newer ones it appears at the center of the viewfinder.

	Camera Anatomy - Rangefinder Cameras
		Rangefinder cameras fall into two separate sub catagories, those in which the rangefinder is coupled to the focussing mechanism of the camera (coupled rangefinder cameras) and those in which the rangefinder is used to determine the distance only - which is then transferred to the lens manually, clearly a less convenient, but cheaper, option.
		In use, the photographer peers through the rangefinder to observe a main image onto which is superimposed a secondary image (often tinted yellow covering a small circular part in the centre of the main image).
		The alternative is to have a central composition window and two independent rangefinder windows, this is a compromise in it's own right as the photographer now has to focus through the rangefinder and compose through the viewfinder.

	Leica - Wikipedia, the free encyclopedia
		Conceptually bridging the Rangefinder Leicas and the SLR Leicas was the Leica Visoflex System, a mirror reflex box which attached to the lens mount of Leica rangefinders (separate versions were made for the screwmount and M series bodies) and accepted lenses made especially for the Visoflex System.
		Camera rangefinders are inherently limited in their ability to accurately focus long focal-length lenses and the mirror reflex box permitted much longer length lenses.
		Furthermore, certain LTM and M rangefinder lenses featured removable optical groups which could be mounted via adapters on the Visoflex system, thus making them usable as rangefinder or SLR lenses for Visoflex-equipped Screwmount and M rangefinder cameras, as well as being usable on Leicaflex and R cameras.

	Olympus 35 Rangefinder Cameras
		Rangefinder cameras are what made 35mm a popular film medium and reached their high water mark amongst amateur photographers in the 1950's.
		That said, the XA's rangefinder is problematic indoors or in low light, since it's rangefinder patch isn't as large or bright as any of the full-featured fixed-lens rangefinder cameras from the 1970's.
		With the Rollei or any of the older rangefinder cameras from the 70's one will be able to soldier on, so long as if he or she can forego using the light meter and instead use the "Sunny 16 Rule" to set the exposure.

		In addition, your Bushnell Yardage Pro Laser Rangefinder ’s LCD incorporates illuminated indicators that advise you when the laser is active, what the precision tolerances of a specific measurement are and when the battery charge is low.
		Bushnell' Yardage Pro rangefinders from Optics Planet use an invisible, eye-safe Class 1 Laser beam (as classified by the FDA) which is "bounced" off distant objects with the press of a button.
		Because laser rangefinders "bounce" a laser beam off the target in order to take a measurement, their range is partially determined by the reflectivity of the target.

	Rangefinder FAQ
		A rangefinder uses a rangefinder mechanism to measure and set the lens to the correct distance to the subject.
		Rangefinders may be cheaper and simpler to fix, depending on their design, due to the fewer and lower cost parts used in their simpler design.
		Rangefinders may have shorter delays in taking the exposure, since they don't have to wait for a big mirror to swing or move out of the way before taking the exposure.

	M2/3/4 Rangefinder Restoration
		Restoring a rangefinder in a M camera requires complete dismantling of the optical system, splitting the prisms, cleaning with nitric acid, and placing a layer of aluminium onto the optic by vapour deposition in a vacuum chamber.
		The original M3 rangefinder was expensive to produce, the viewfinder assembly alone had 2 optics and 2 prisms cemented together, which makes re-silvering more difficult, as these 4 elements have to be aligned and re-cemented exactly after restoration.A lot of effort went into the production of the the M3 RF unit.
		The rangefinder in the first double stroke M3's went through several modifications before finally being discarded in favour of the M2 type, of which the basic design, is still used in the latest MP cameras and continued after M3 production ceased.

	Epson R-D1 Digital Rangefinder Camera: Digital Photography Review
		Epson felt that if the companies were to use the rangefinder camera platform—a platform that is being left in the wake of progress toward the digital age—and if they were to merge Epson's digital image processing technology with Cosina's advanced optics technology, they might be able to discover some completely new creative photographic possibilities.
		In other words, the R-D1 is simultaneously a state-of-the-art digital camera that offers outstanding performance and image quality, and a throwback that offers camera buffs the look and feel of a vintage film camera, as well as the joy of skillfully using their camera as a tool.
		A rangefinder is a type of camera that has a built-in device for measuring distance based on the principles of triangulation.

	Olympus 35-SP Rangefinder Camera
		With regard to its light meter, the 35SP is the only fixed-lens rangefinder of the period to come with a dual mode light meter, one that is center-weighted in its normal mode and with a push of a button the meter switches over to its highly regarded spot-metering mode.
		Since the light cell is not located on the lens barrel as in other fixed-lens rangefinders, filter compensation in the AE mode is done manually by by setting the ASA speed to 1/2, 1/4 or 1/8 of the actual film speed - depending on the type of filter in use.
		This is a precision rangefinder camera that deserves to be used instead of posing behind a collector's glass case.

		The distance to be measured is displayed within the magnified monocular providing the hunter and golfer with a true view of the field and path.
		Rangefinder emits invisible, eye safe, infrared energy pulses.
		A high speed clock and a complex circuitry are used to calculate distances immediately, by measuring the time taken for each pulse to travel from the rangefinder, to the target, and back.

	Photoethnography Equipment
		With the demise of TLRs as contemporary cameras and only large format photographers using ground glass, single lens reflex and rangefinders remain as the major current manual focusing options for curmudgeonly photographers who refuse to go auto-focus (or who like myself, use AF for their professional photography, and manual focus for their fine art photos).
		Coupled rangefinders connect the rangefinder distance gauge directly to the camera lens, so that when the rangefinder is in focus so is the camera.
		Rangefinders are a bit lighter than most pro SLRs, but no rangefinder is as light as the 365 gram Canon Kiss 5 (Rebel Ti to Americans).

	Matt's Classic Cameras: Rangefinders & Compacts
		Compact rangefinder by Chinon for GAF, a near-clone of the Konica C35.
		Rangefinders' popularity waned with the rise of SLRs in the Seventies and Eighties, SLRs being versatile and easy-to-use and having their own increasingly sophisticated electronics (grid focusing, what?).
		But rangefinders seem to be currently enjoying a secret renaissance, coming now as a sophisticated alternative to point-and-shoot cameras with some of their ease of use, but without the bulk of an SLR system.

	Konica C35 Series
		When you consider that the vast majority of compact 35mm rangefinder cameras had a close focus limit of 3 feet, you can probably easily understand why I truly wish that Olympus and Canon had followed the Konica lead on this one.
		The rangefinder is crisp, with the dual image lining up smartly, while the viewfinder is bright and the bright frame lines inside are easily seen.
		Interestingly, while the camera lacks a rangefinder, the bottom left corner of the viewfinder (as viewed from the front of the camera, lens on) has a small, triangular window within the viewfinder mask.

	Adjusting the Kalart Rangefinder
		Your rangefinder is probably already adjusted properly for the normal lens with which the camera was shipped.
		That is, focus the camera on a target that is in front of the lens and adjust the rangefinder for a target on the same plane directly in front of the rangefinder.
		In use, the camera is pointed at the object being focused on first through the rangefinder and the lateral coincidence will make you point the rangefinder straight, the camera is focused and then aimed using the optical or wire finders.

	Kodak 35 Rangefinder (Site not responding. Last check: 2007-10-07)
		The Kodak 35 was introduced to compete with the Argus A. Unfortunately, in 1938 Argus introduced the C-series with a coupled rangefinder.
		To compete with the Argus C-series, the Kodak 35 rangefinder model was introduced in 1940.
		The hastily-designed rangefinder is gear-coupled to the front lens element through a cumbersome external linkage.

	Lenses For Nikon RF Mount
		The rangefinder lenses for the S-type Nikons are decent performers, but clearly most cannot compete with today's most advanced designs.
		In common with most rangefinder lenses, it is quite small and difficult to operate by today's standards due to the inconvenient size of the lens in conjunction with the obscure placement of the aperture control within the lens barrel.
		It attaches to the camera through the external, wide bayonet mount, and can be focused either directly by the lens collar, or from the camera using the focusing thumbwheel.

	Matt's Cameras: Kodak 35 Rangefinder
		This is an early Kodak rangefinder from the 1940s, pictured here with a Series VI filter adapter (mine came with one, now I have two!).
		The viewfinder and rangefinder windows, which are tiny, aren't functionally smaller than on the Argus C3, which I like as well, so there you go.
		Split-screen rangefinder is in a separate window from the composing viewfinder, as on the Argus C3, so you go back and forth a lot.

		However, many of the budget rangefinders costing under $100 US cited here may well be easier to use, have more features like auto-exposure and built-in metering, and even offer extended flash synch speeds.
		While these rangefinders are similar in size and weight to many compact and larger SLRs, they offer leaf shutter flash synch at any speed (up to 1/500th second) and more accurate focusing in poor light conditions (thanks to long baseline rangefinder designs).
		The Canonet QL series rangefinders are often recommended as budget entry level rangefinders for those who can live with the single non-interchangeable lens design.

	Leica Rangefinder issues (Site not responding. Last check: 2007-10-07)
		The rangefinder in theory measures a point in space at only one exact distance, which is not feasible in real life.
		So as a bottom line for rangefinder accuracy we must state that the distance of the focusing error is at least equal or less than the DOF distance.
		As the rangefinder is based on triangulation, we do not use in our equations lp/mm but angular resolution.

	Chronology and specifications of Yashica rangefinders
		The camera needs to be handled with care [as any camera should be anyway] due to the light meter which has a moving needle indicator [galvanometer] as found in many popular exposure meters.
		Be sure to drape the cable from the strobe gun to the PC socket on the left side of the front of the camera, so that it does not go over the fresnel lens light sensor.
		An extremely useful feature dropped in subsequent Yashicas, is a small barely noticeable stubby lever on the focussing ring, that greatly simplifies bringing the split image finder into sharp focus pronto, without fingers blocking the viewfinder or light sensor.

	Leica FAQ - DIY rangefinder adjustment
		The rangefinder distance calibration is done by the eccentric pivot of the rangefinder arm and the eccentric mounting screw of the rangefinder arm roller.
		The roller position determines the starting point of the rangefinder arm travel (infinity) and the eccentric pivot adjusts the ratio of rangefinder movement to lens cam movement by varying the length of the arm.
		A shorter arm gives you a larger movement of the rangefinder pivot for a specific amount of lens cam movement; and, a longer arm gives you less movement of the rangefinder pivot for a specific amount of lens cam movement.

	Photokina 2004: rangefinder scene (Site not responding. Last check: 2007-10-07)
		The finder windows have an anti-reflection coating that diminishes clearly the flare of the rangefinder patch that occurs in some situations when strong lightsources are shining obliquely into the finder.
		As the rangefinder market was already under attack from the slr camera, the competitors (Zeiss, Canon, Nikon) decided to jump on the slr bandwagon.
		There were many revolutionary changes in the M5, including the famous two flat retainers for the shoulder strap, the metering though the lens with a moveable metering cell in front of the film plane, and a shutter that could function till 30 seconds.

	Contrast of M6 rangefinder
		I think the strength of the M6 rangefinder, especially compared to cheaper rangefinder cameras, is the (usually) higher magnification and image size and the greater baseline of the rangefinder.
		The rangefinder is hard to see, of low contrast, flares out at the slightest provocation, and in general does not inspire confidence for critical focussing.
		I personally find the rangefinder of the Cosina Bessas to have better contrast and to be much easier to focus with (despite the shorter rf baseline).

	Kiev 4 35mm camera
		With the widest of rangefinder bases and clearly engraved depth-of-field scales, the Kiev offers pin-point focus of a single object or the accurate spread of sharpness between two objects at differing distances in a way that is unrivalled by the generalised, imprecise near-accuracy of a modern autofocus camera.
		It was more than a little influential in the design of Nippon Kogaku's rangefinder cameras, the Nikon S series (though they couldn't manage to duplicate the brass shutter blinds), which eventually, with the addition of a pentaprism, became the Nikon F and the foundation of the Nikon empire.
		It doesn't couple with the rangefinder and has to be focused by use of its distance scale, but since f6 is its maximum aperture, an estimated distance is sufficient.
