What kind of camera is a rangefinder? What are the advantages?

A rangefinder camera, as the name suggests, is the image seen in the viewfinder that is different from the last image that is refracted through the lens onto the film. Because the framing system is independent, there is a certain parallax, and it takes some time for the user to get used to it! In the more than 100 years of camera history, the rangefinder has undoubtedly been a very important component.

It has a wide variety of types, different structures, and its own profound cultural characteristics and photographic characteristics! Therefore, it is necessary for everyone to get to know this familiar stranger!

a) The background of the generation of the rangefinder camera.

It's too early to say, but in the early stage of the formation of a camera industry, hand-based camera products were mainly influenced by the painting camera obscura, and products with coaxial framing methods of wool screen occupied an important position.

But this framing method is too inconvenient. First, in the early stage of the development of photosensitive materials, sufficient light environment is required when taking pictures; Second, the framing of the wool screen is easily disturbed by external stray light. This limitation inspired a revolution in the viewfinder, and the sidefinder was a revolutionary product born in response to the times!

There are several early forms of rangefinder framing. The simplest one is called the frame viewfinder, which can be mounted on any coaxial viewfinder camera as an additional viewfinder). It is widely used because it is easy to make and can be used for framing accuracy when shooting scenes from a certain distance!

For example, the Chambre Automatique produced in France in 1860...

Compared to the SLR, the benefits of the rangefinder are:

1.The rangeshaft is generally lightweight and portable.

2.The quality of the lenses is relatively good, such as Laika, Contex, Konica, and even Volenda.

3.There is no depth of field, which is advantageous in low light, but it requires a certain amount of experience and adaptability.

4.No framing through the lens, no need to lift the reflector, and the relative vibration is less than that of the SLR.

5.Due to the different ways of framing, the rangefinder has an inherent advantage in wide angles.

Of course, the sideshaft still has many shortcomings, and it belongs to the previous generation of SLR products.

For example, it is inconvenient to use filters, most of the rangefinders are not spotted, the telephoto end is very limited, and so on.

Let's look at this link, for more details, I just bought the sideshaft of the Whitt 2, less than a week ago, and I've been paying attention to this issue lately.

I don't know what you're asking for, but I'll give you some personal advice.

The rangefinder is a product of the DSLR camera, which is the early professional camera, although now in the digital age, but the reliability of mechanical cameras is still unquestionable, and the rangefinder mechanical camera can be used as the basis for the introduction to photography, if used well, other cameras are like toys.

The 60-year-old Shanghai brand 58-II rangefinder camera has been included in the collection field.

1. First of all, it is more convenient to carry, because there is no reflector and pentaprism module. The fuselage can be designed to be slightly thinner and lighter. In particular, a small automatic rangefinder camera with a telescopic lens.

The second is that the body vibration of the rangefinder camera is small when taking pictures, and the noise is small, because there is no reflector, when shooting, the mirror is avoided from taking off. Vibrations and more pronounced sound are also more conducive to hand-held capture of clear images at low shutter speeds.

3. Then there is the small body, and the rangefinder camera does not give people a sense of oppression like professional SLR cameras. The compact body of the rangefinder camera is not a little aggressive, and it can get a more natural shooting effect. Shooting with a rangefinder camera is a great tool for humanities subjects such as street photography.

4. Finally, the composition changes more freely when the camera is framed, and the lens is not the same field of view. Instead, the field of view corresponding to the lens is captured through different frame lines. Therefore, when we compose a picture, we can not only see the actual scene in the frame, but also the surrounding scenery, so that we can quickly adjust the composition.

Due to the focus baseline and the lack of a mirror, the general wide-angle lens can be made very close to the bottom of the mirror, and the structure and imaging are better than that of the SLR. Therefore, the short, standard focal length is its strong point, and the telephoto is almost a virtual banquet. The advantage of the SLR is that the focal length covers a wide range, and it has an incomparable advantage in the telephoto and macro axis.

A wide-angle lens is a photographic lens with a shorter focal length than a standard lens, a larger angle of view than a standard lens, a focal length longer than a fisheye lens, and a smaller angle of view than a fisheye lens. Wide-angle lenses are divided into two types: ordinary wide-angle lenses and ultra-wide-angle Bu Xiangbi lenses. The focal length of an ordinary wide-angle lens is generally 38 24 mm, and the angle of view is 60 84 degrees; The ultra-wide-angle lens has a focal length of 20 13 mm and a viewing angle of 94-118 degrees.

Due to the short focal length and large angle of view of the wide-angle lens, it is possible to capture a large area of scenery in a short shooting distance. The lens of a wide-angle digital camera has a short focal length, a wide angle of view, and a deep depth of field, which is more suitable for shooting larger scenes, such as architecture, landscapes and other subjects.
