What are the development stages of Japanese photography?

1977, KONIKA C35AF head-up framing camera, the first autofocus (AF) camera, produced by KONI Sixth Company.

198 1 year, Sony Corporation of Japan produced a still camera-MAVICA camera, which recorded optical signals as analog electrical signals and stored them on floppy disks, laying a foundation for the realization of digital imaging system.

1982, Nikon's FM2 fully manual mechanical camera has a maximum shutter speed of 1/4000 seconds and a flash synchronous shutter speed of 1/200 seconds. This model has become the first choice for many professional photographers because of its excellent performance.

1983, Nikon company produced 135 single-lens reflex camera-Nikon FA camera, which has the function of zoning evaluation and photometry, greatly improving the photometry accuracy.

At present, electronic technology is widely used in the field of cameras, making automatic metering, automatic focusing and automatic exposure a reality. The popularization of optical transfer function theory, the development of new optical materials and the improvement of optical processing technology have improved the quality of lenses. Aspheric lenses have appeared, and lenses are developing in series. Japanese cameras came from behind and began to take advantage of automation and output.

stage Ⅱ

1985 In February and September, the 135 single-lens reflective autofocus camera produced by Minolta Company of Japan was introduced, which marked that the camera production had entered a stage dominated by electronic technology and gradually intelligent.

1In April, 1986, Nikon F50 1 single-lens reflex camera with single autofocus mode and continuous autofocus mode, which can be used with non-autofocus lens, allows users to reduce losses when updating the camera.

1988 in may, minolta introduced the intelligent Dynax7000I 135 single-lens reflective autofocus camera. The camera can focus on the shooting position in advance according to the speed of the moving object.

1988 12, Nikon introduced Nikon F4 135 single-lens reflex camera. Nikon F4 integrated almost all the functions of the then 135 single-lens reflex camera. It has the functions of auto-focus prediction, L/8000 second high-speed shutter, automatic surround exposure, highlight/shadow control, trapping focus and so on. So it was equipped by NASA on the space shuttle Discovery.

1995 Kodak Company introduced a 6.23 million pixel (2036×3060) Kodak DCS 460 digital camera, which converted the image signal of CCD into a digital signal and recorded it on the disk. The camera adopts the body and lens of Nikon F90 camera. The birth of digital camera indicates that computer technology has entered the camera field in an all-round way.

1996, Nikon introduced a Nikon F5 camera with 1005 pixel CCD as the photometric element, which can evaluate the brightness of each part of the scene, and can connect 8 frames per second under the condition of tracking AF.

1996 in may, Kodak, Nikon, canon, minolta and fuji jointly launched APS (advanced photographic system) film, camera and magnifier. APS film is 24mm wide, small in size, quick to install and does not damage the film. The magnetic coating on the film can record the shooting and expanding information.

At this stage, due to the continuous adoption of the latest electronic scientific and technological achievements, the camera is becoming more and more intelligent and convenient to operate. Digital image technology has developed rapidly. Although digital image is not as good as silver salt image in resolution, latitude and sensitivity, it has been widely used in news, advertising, military, scientific research and other fields because of its fast transmission speed and convenient processing.
