That year summer

R lens can finally series applied to Contaxflex camera focal length, meet the needs of each user needs. So far Tessar lens family organization construction has been basically completed, since 50time up to now, there has been more improved by the application of Tessar lens photographer. At the same time,IP camera manufacturer other camera factory, have draw lessons from Tessar lens design and production of a series of Proteus species, which also includes Leitz early Elmar series lens. If anyone want to collect Tessar lens, then present in the world, there are at least more than 400 different species of Tessar options.

A large family of Tessar to show people, optical technology how to make1840a simple structure of the four mirror, become today still play a decisive role in the photographic field lens.

Basic component

Camera lens

The lens so that the scene like focusing on film. In order to make the different location of the object image is clear, with the exception of the lens itself needs correction

The camera as if poor, should make the object distance, image distance keeping conjugate relation. For this, should be able to move around the focusing lens, thus better cameras in general should have the focusing mechanism.

Viewfinder

In order to determine the scenery being shot range and is convenient for the picture composition, the camera should be equipped with a viewfinder. Modern camera viewfinder with distance,PC camera manufacturerdab4d59ck focusing function.

The shutter and aperture

Exposure control mechanism -- the shutter and aperture

In order to adapt to different brightness and subject, in order to obtain the correct amount of photosensitive film, must control the exposure time and intensity of light entering the lens. Then the camera shutter must be set to control exposure time, and set the aperture through the light hole size is regulated to control the amount of light.

Film transport counting mechanism

In order to prepare for the second time, after the exposure of the film needs away, the unexposed film to pull over, so the modern camera needs to have the film transport mechanism.HD webcam manufacturer The film has been shot to indicate the number of sheets, requires a counting mechanism.

Fuselage

It is the camera obscura, and each component of the combination of camera. Block diagram representation of available camera of the most basic components.

In fact, on camera to this basic function, whether early" Silver Edition camera", or have a height of electronic, automation, computerization of the camera, its basic principles are not much difference.
