2, manual focusing camera

Features: manual focusing, low degree of electronicization, mostly with the basic functions of cameras, mostly with mechanical shutters, without batteries. Manual focusing SLR cameras still have a place in SLR cameras. But there are fewer models. Many manufacturers have stopped producing manual focusing SLR cameras.

the models currently available in the market are:

high-end: Nikon F3, Canon F-1, Contax RTS-III, Leica R8,R7,R6.2.

middle-end: Nikon FM2, Minolta X-7

low-end: Nikon FM1／FE1, Minolta X-3. It has the characteristics of 35mm and large-format camera, convenient operation and large film area. Manual focusing is the main function, with less functions. In recent years, Pentax, mamie Ya, etc. have also introduced auto-focusing mid-range cameras. Because of the large area of the film, it can obtain better image quality and is convenient to use, which is chosen by more portrait and landscape photographers.

high-end: Hasselblad series (51c,53cw,), Lulai series (68,66,61)

middle-end: mamie Ya series (RB67,645), Pentax series (67Ⅱ,645N), Bilang House series

low-end. Using film, there are 4*5, 8*1 and other specifications. The camera is bulky and complicated to operate, but the perspective and depth of field can be adjusted by adjusting the back of the camera. Polaroid film can be used for pre-shooting. It is chosen by many photographers in advertising, architecture and scenery.

the famous brands are: sinar, jinbao, Lin Hafu, etc.

The above pictures are pictures using film. Today, there are many cameras using special film-Polaroid cameras, and cameras without film-digital cameras:

Polaroid cameras: also called once-through imaging cameras. Directly exposed to special photographic paper, you can see photos in one minute, suitable for taking pictures, etc.

digital camera: one of the challenges of traditional photography comes from digital cameras, which use CCD as photosensitive element instead of traditional film. It has the characteristics of convenient use, convenient transmission and convenient storage. However, at present, digital cameras are expensive, and the imaging quality can not be compared with traditional film. If the requirements for pictures are not high, mainly used in computers, digital cameras are a good choice. At present, digital cameras are also widely used in the fields of news and advertising, but the price of the equipment used is very imaginable.
