By , they were already giving way to a newer option, the SLR, which is all known as a single-lens-reflex camera. For the most part, SLR camera are not at all pocketable. Leica is still in business. The photo below shows the rangefinder focusing apparatus of a modern digital Leica, which isn't much different than its forbearer, the Leica M3 of the late 'ies. If it is coupled to the lens, a rangefinder apparatus is what allows the photographer to focus quickly and with surprising precision.
A typical rangefinder camera of the post era is recognizable by having a large viewfinder window built into the front of the top cover, plus a second smaller front facing window off to the opposite side and frosted window in between the two. A rangefinder camera incorporates a separate optic system from the main imaging lens in order to assist the photographer when focusing the camera. When the photographer adjusts the lens focus ring on the imaging lens on camera with a coupled-rangefinder, the small secondary image projected from the the RF window will appear to shift sideways.
Once the RF image coincides with the main VF image to form a single image, the camera lens is in proper focus. What not to do while focusing: If the photographer puts a finger over the RF window at the front of the camera - the rangefinder patch will magically dissappear from the viewfinder. The main weakness of the typical rangefinder camera's design is the optics for its viewfinder usually has a fixed magnification and field of view.
In other words, the viewfinder's optical path is not through-the main imagining lensR. Unlike an SLR camera, whenever the photographer mounts a lens of a different focal length to an RF camera - the image magnification that one sees in the viewfinder does not change one bit. Consequently, early rangefinder cameras required the use one or more accessory viewfinders to provide the proper framing necessary for any lens other than a 50mm focal length on a 35mm camera.
An honorable mention : Canon rangefinders from the early to mid s used a viewfinder with variable optics. An adjustment lever located beside the viewfinder changed position of the viewfinder optics to three specific magnifications, suitable for a 50mm, mm or a mm lens. For whatever reason, the downside was the optics used by Canon were not of the highest quality and therefore, not very sharp at the highest magnification.
Plus, the 28, 35 and 85mm lenses still required the use of an accessory viewfinder. The image below shows an example of a photographer using an accessory viewfinder with a wide-angle lens.
He is using an add-on viewfinder with the wide-angle lens, because the lens exceeds the field of view of the camera's built-in viewfinder. The accessory viewfinders slide into the top mounted accessory shoe - which is today has evolved into the flash shoe. This type of accessory shoe is sometimes referred to as a "cold shoe" by photographers. The best accessory viewfinders provide a magnification. In other words, the photographer has his or her normal vision, but with a set frame lines superimposed into center of his or her field view.
This proves to be quite useful for photographing street action. On the other hand - this can be very disconcerting to someone who has only used a single lens reflex camera. Someone could write an entire web page on accessory finders for an RF camera. After - the high-end solution to reduce the need for accessory finders was to to add two or three sets of frameline masks that could be independently superimposed to the rangefinder camera's above-the-lens viewfinder. The other solution was to have a complete set of reflected frame line at all times towards the viewfinder eye piece.
Each set of frame lines for a higher focal length lens occupies only a cropped portion of the full viewfinder.. Bottom line - when using a 90mm or mm lens, the photographer - the framelines occupy a small area within center of the viewfinder. In the above photo, the 90mm frame lines on my Leica M2 have been enhanced in Photoshop, but one gets the idea of what they look like in the viewfinder.
In real life the frame lines are the same color as the rangefinder patch. More importantly, notice how the 90mm lens protrudes into field of view, which is slightly wider than what is required for the use of a 35mm focal length lens.
More than any other on image on this web page, the above photo shows what I mean by the phrase, "above-the-lens viewfinder". Also, the projected frame lines move automatically as the photographer focuses the lens to prevent parallax errors.
Owner's of rangefinder cameras designed before need to be aware of parallax errors as one focuses on objects that are very close to the camera. When mounting either a 50mm, 90mm or mm Leica M-mount lens the proper set of frame lines would automatically appear in the viewfinder.
The Leica M3 camera was introduce just before and to put it mildly, it set a new standard for above-the-lens viewfinders. Yet another honorable mention but this time for the Nikon SP, which was introduced in with a viewfinder magnification and four selectable sets of frame lines in its main viewfinder. I mention a main viewfinder - because to raise the bar against the Leica M3 and by this time the less expensive Leica M2, - Nikon SP added a second viewfinder off to the side for composing with either 28mm or 35mm focal length lens.
The main view finder of the SP features frame lines for either a 50mm, 85mm, mm or mm lenses. As a result of the improvements to the SLR which were in place by - the popularity of rangefinder cameras began a precipitous decline. Auto focus and auto exposure were in long way in the future - but within a couple of years, the addition of a through-the-lens light meter further hastened the popularity of the SLR especially amongst well to do amateurs.
So much so, that both Canon and Nikon would cease producing interchangeable lens rangefinder cameras, before the end of the decade. By , with the exception of Leica, the sales of rangefinder cameras were for the most part relegated to consumer grade 35mm cameras with fixed-lenses. Fixed-lens 35mm rangefinder had been a staple product in the camera market since Fixed lens rangefinders were the affordable option amongst 35mm camera offerings.
The bad news is a fixed-lens rangefinder offers only the single focal length lens that is built onto the camera. The good news is that the lenses fitted to the cameras were usually very well spec'd for the times.
More often than not the fixed-lens rangefinder camera's image quality not only equalled of a prime lens on an SLR - but would almost alway surpass images taken with a consumer zoom lens that became popular in the following years. This allowed them to take photos in low light - without having to install a flash unit. Canon, Konica, Minolta, Olympus and Yashica pretty much dominated the fixed-lens market during the s. In addition to the usual fast prime lens, all of the 35mm fixed-lens rangefinders from the s had an automatic exposure mode - which prior to wasn't a common feature to most SLR systems.
Prior to , if you bought a 35mm camera from a reputable manufacturer, it was built on a metal chassis and its outer shell was made of pressed brass or a stamped steel. On top of that, the lens sits closer to the film plane in a rangefinder, often resulting in sharper images. A mirror-less body also means no shutter shake. Viewfinder Rangefinders have a larger viewfinder that is separate from the lens which allows a greater field of vision and, in turn, enhances your ability to see your subject enter the frame, helping anticipate your shot.
Rangefinders are also harder to focus in low light. Online Film Developing. Professional film developing and scanning for 35mm, medium, large format, and disposable cameras for over 45 years.
Mirror Since SLRs contain a series of mirrors, you see, compose, and focus through the lens. This allows you to preview your depth of field which makes SLRs great for portraits and action photography. With their straightforward split image focusing, what you see is what you get. Additionally, SLRs commonly have faster shutter speeds than most rangefinders, which gives you the ability to stop down and shoot at faster apertures in daylight. And they will be manual focus…yeah manual focus. This gives you the chance to zone focus and to develop your skills at measuring distance.
If this sounds terrifying, it is not, once you get the hang of it you will constantly be aware of the distances of the things around you. With the advent of digital technology we have seen a resurgence in the use of rangefinders, especially with the release of the M9 from Leica. This introduced a great deal of people to RF photography, who in some cases had never been into photography before. And as an offshoot there has also been a rise in the amount of people who shoot film rangefinders.
But what cameras are they looking at? There are lots of different options available out there. There are a lot of fixed lens rangefinders that are cheap, easy to find and work very very well. This is a difficult question, as it covers so many variables and it is an essay in its own right. Ultimately the best camera for you is the camera that most suits your style, feels right in your hands and that you get joy from using.
That could be a disposable camera or the lastest Leica Monochrom. As with any camera you have to think about how much money you want to spend and what you want to use it for. Take your time, and do your research. Rangefinder cameras — What are your options.
