How many sizes and models are there in arri film cameras? 6 types.

A movie camera refers to an optical machine that can continuously capture images of a subject.

The imaging principle is the same as that of a general camera.

It mainly includes photographic lenses, exposure devices, film transport mechanisms and cassettes.

Types of film cameras: 1. By model.

Movie cameras can be divided into three types: large, medium and small.

2. Press the film width.

It can be divided into 70mm, 50mm, 35mm, 16mm, 8.75mm and 8mm.

3. According to usage.

It can also be divided into stunt cameras, high-speed cameras, subtitle cameras, time-lapse cameras, micro cameras, underwater cameras and aerial cameras.

In recent years, movie cameras have mainly developed in the direction of portability, miniaturization, low noise, and automation.

Most of the filming of educational films uses 16mm cameras.

FX3 (model name: ILME-FX3), which is currently Sony’s most compact and compact movie camera, is priced at 32,000 yuan.

What types of camera viewfinders are there? Viewfinder types 1. Optical viewfinder The optical viewfinder is installed directly next to or above the camera.

The viewfinder itself has an objective lens and should be placed as close as possible to the camera lens.

This kind of viewfinder allows the photographer to directly view the image on the ground glass (or film), select the shooting range, and correct the image clarity. Its disadvantage is that the image seen is not very bright.

2. The optical reflection viewfinder reflects part of the light incident through the main lens of the camera into the viewfinder, allowing the camera operator to see the image of the scene at any time.

3. The electronic surveillance viewfinder uses the fluorescent screen of the television camera tube to replace the observation screen of the reflective viewfinder.

It generally consists of a small flat tube that can form a clear and bright image on a screen with a diagonal length of 130 mm or 180 mm.

It not only displays the entire image shot outside the film gate, but also displays a bright frame line generated by the signal processing device, so the composition can be designed accurately.

In addition to the devices introduced above, movie cameras also have focusing devices, exposure control devices for adjusting aperture, zoom selection and adjustment devices, foot (or meter) meters, tachometers and other devices.

Although there are many models of movie cameras, in terms of their basic structure, they are nothing more than the ones introduced above. You can make analogies based on your own actual situation, so I won’t go into details here.

Although digital photography has gradually replaced film, film's ability to control color and depict picture details is still better than any digital camera developed so far. If the budget allows, it is still best to use film as a pre-production shooting

best choice.

For example, when shooting on film, an ARRI535 camera is used, which uses Kodakvision2 series film and Carl Zeiss lenses.

Film shooting and production must rely on sophisticated film cameras, but the camera is only one factor that controls the quality of the picture.

The quality of the picture is also closely related to the photographer's creative skills, the characteristics of the film, the quality of the lens, the level of post-production, etc.

Nowadays, the mainstream movie cameras mainly include Panavidin from the United States and Aliflex from Germany. (Atong from France and Movicon from Switzerland are also very good machines but are not common now).

Hollywood mainly uses Panavidin, while photographers in Europe and Asia are accustomed to using Ariflex cameras.

The main manufacturers of 35mm movie cameras used in the world's film industry include the American Panavision Company, the German ARRI Group and the French AATON Company.

Among these three companies, Atong's 35mm camera 35III is mostly used for documentaries, feature films, and promotional films. Most American films use Panavision cameras. The latest and most advanced model in its series is the Millennium model.

Panavision cameras use Panna lenses designed and assembled by the company in-house, and their quality is excellent.

The anamorphic lenses, in particular, are of excellent quality.

Among the cameras currently produced by the German Allais Group, the latest and most advanced model is the ARRICAMST model (see the attached picture below).

Alai Group does not produce lenses itself, but it cooperates with Zeiss to produce UP series lenses with PL mount, which have excellent image quality.

Most of the films used in making movies and TV commercials are film films from the American Kodak Eastman Company, with sensitivities ranging from ISO50-800.

The film specifications used in 35mm movies are the same as 135 film used in photography.

At that time, Oskar Barnack, the inventor of the Leica camera, directly borrowed 35mm film film.

However, although the current 35mm film film is the same as the 135 film for photography in terms of specifications and basic structure, it is very different in terms of processing technology and specific performance indicators.
