People often ask, who makes rangefinder lens?
Let’s find out!
Who Makes Rangefinder Lens?
Rangefinder lenses are made by many different manufacturers. Some of them have a very good reputation, while others are not so well known.
Rangefinder Camera
Rangefinders allow photographers to set their shutter speeds and apertures without guessing at the right combination. They’re useful for taking pictures when there isn’t enough light.
Digital Rangefinder
The digital image technology was applied to rangefinders for the first time in 2003 when Epson introduced the Epson R-1, which used a Leica M-mount lens. Later models included the R-2, R-3, R-4, R-5, R-6, R-7, R-8, R-9, R-10, R-11, R-12, R-13, R-14, R-15, R-16, R-17, R-18, R-19, R-20, R-21, R-22, R-23, R-24, R-25, R
Leica M
Leica has been making cameras for over 100 years. Its first digital rangefinders were introduced in 2006. It lacks some of the most popular functions found on today’s digital cameras, including autofocus, live view, movie mode, and face recognition. It doesn’t offer any telephotos past 135mm.
Later, Leica released two new models, the Leica M (Typ 246), which adds a live preview, a video recorder, and focus assist, and the Leica M Edition 70, which is similar to Typ 246 but omits a rear viewfinder as a homage to classic Leica rangefinders. The M Edition 70 also comes with an improved version of the original Leica lens mount that allows it to use lenses from other manufacturers.
The Leica M series was discontinued in 2011 when the company launched its latest model, the Leica T.

Pros and Cons
Viewfinder Parallax
A rangefinder’s viewfinders are offset from their lenses so that the image seen through them isn’t exactly what will be captured by the camera. At larger distances, this parallax effect is negligible, but when shooting extremely close up, the rangefinders become awkward to use because the viewfinders don’t point directly at the subjects anymore.
A rangefinder’s viewfinder projects a bright lighted grid that moves as the camera focuses, helping correct parallactic errors. Some rangefinders also automatically adjust their field of view depending on the distance between them and the subject.
A camera obscura is a device used to create images by capturing light onto a piece of paper or another medium. The process was discovered in the late 17th century by the German scientist Johann Heinrich Schulze who called his invention Camera Obscura (Latin for dark chamber).
He noticed that objects cast shadows on a wall inside a darkened room. By placing a sheet of white paper against the inner surface of the window he could see the shadowed areas of the object cast upon the paper.
Large Lenses Block Viewfinder
Lenses larger than 35mm (35 mm film) tend to block a substantial part of the view seen through their viewfinders. As a result, lens designers are forced to design smaller lenses.
Hoods designed for rangefinders often have holes cut into them to increase the visible field of view. This is not possible with large lenses because they would obstruct too much of the viewfinder image.
The viewfinder in the Leica M6 has an optical pentaprism which allows it to be used as a rangefinder or a viewfinder. The viewfinder can also be removed and replaced by a separate hood.
Difficulty Integrating Zoom Lenses
The range finder is not readily adaptable to zoom lens usage, which has a continuously varying field of view. The single true zoom lens for rangefinders is the Contax G 2 Carl Zeiss 35– 70mm Vario Sonnar T* Lens with an integrated zoom viewfinder.
Very few zoom lenses allow the user to choose between two or three focal length settings. The range finder can become misaligned, causing inaccurate focusing. A zoom lens that allows the user to select one of several fixed focal lengths is more useful than a zoom lens that does not have this capability.
Zoom lenses are usually designed to be used at their widest setting and then stopped down to achieve the desired aperture. This means that the maximum magnification available is limited by the minimum f-stop (the smallest opening in the iris) required to stop down to the chosen focal length.
Absence of Mirror
The absence of a rear projection screen makes it possible to make much thinner and lighter wide-angles than would otherwise be possible. A wide-angled lens can be used without any problems if the camera does not have a built-in optical finder.
In such cases, the photographer must rely on an external optical finder, such as a prism attachment or a reflex viewing device. Rangefinder cameras were especially popular among photojournalists because they could fit easily into small bags and pockets.
Since there is no moving mirror, as used in SLRs, there is no momentary blackout of the subject being photographed.
Field of View
A rangefinder camera usually has a wider angle of view than the actual focal plane of the optical system. This allows the photographer a wider area to compose his picture without having to move closer to the subject.
With a wide angle of view, the photographer can also get a good idea of what he is about to capture before taking the shot. However, with a wider angle of view comes a narrower depth of field.
This is because the distance between the closest object and the furthest object that appears acceptably sharp becomes shorter. For example, if the focal plane is set at 10mm, then objects at distances of 20mm and 30mm will appear blurred.
To compensate for this, the photographer may choose to increase the aperture setting, thereby increasing the amount of light entering the camera. Alternatively, the photographer could reduce the shutter speed, thus reducing the exposure time.
Either method will allow the photographer to blur out the background so that only the foreground remains sharply focused.
