Answer 1

I don't quite understand the specific meaning of the expression "Japanese DSLR Chinese". If you want to explain the content related to Japanese DSLR cameras in Chinese, the following is some common knowledge of Japanese DSLR cameras:

Japanese single-lens reflex cameras played an important role in the field of photographic equipment. For example, Pentax's single-lens reflex camera, Pentax ME, was a 35mm full-frame SLR camera with unique specifications and operation methods. It used aperture priority automatic exposure, an electronic focal plane shutter, and a Pentax K lens mount. There were many options for standard lenses, such as SmC50/1.2, SmC-M50/1.4, etc. The shutter was made by Seiko. It was a vertical metal focal plane shutter. The electronic automatic control speed was 8 - 1/1000 seconds, and the manual mechanical control speed was 1/100 seconds. There was a B door, and it also had the shutter lock and winding indication function. In terms of viewfinder, it was a silver-plated pentaprism viewfinder with split-image and micro-prism focusing screen.

In terms of lens manufacturing, taking the manufacturing process of a certain lens in Japan as an example, it included many processes. For example, in the early stage of lens polishing, the lens was manually placed into a precision polishing machine. After polishing, the stains were wiped off, and then the transmission, focus, roundness, and other optical instruments were precisely tested. Then, in the dark light inspection workshop, the lens was manually ensured to be dust-free and assembled with an external fixing frame. Then, the lenses of different size were glued, sealed, and cleaned of impurities before being formally assembled into the lens frame. Finally, the assembled lens module was installed into the lens, and then installed on the camera for final image correction and camera inspection.
