When did the first domestic film SLR camera come into being?

(The picture cannot be uploaded) The 58-I camera in the 1950s was produced by/kloc-0, a newly established Shanghai camera factory in June, 1958. It is an imitation of Leica Ⅲ B camera 1938 made in Germany. it

Type 58-I

Its production marks the beginning of China's camera industry, so it has the epoch-making significance of "zero breakthrough". Main production year: 58-59, with a total production of 65,438+065,438+098. Main functions: 4 lenses and 3 groups of antenna insertion, f = 1:3.5f = 50mm, horizontal curtain shutter, speed divided into T gate and B gate, 1-65438+. Automatic ranging, automatic film stop and automatic counting; M39* 1 threaded interface price: 12000 yuan. Type II This machine is an improved version of Type 58-I .. 1959 officially put into production. The biggest improvement is to combine the ranging window and viewfinder into one, and add the X-flash synchronization structure. Main production year: 59-62, total output 1 1888. Price: 1000 yuan. Type 203 from the 1960s. This is the last 120 folding camera named after "Shanghai". It is an upgraded product of model 202 camera. It was one of the best-selling camera products at that time.

Type 205

Main production year: 1964- 1977, total output 3 1 1446, first export 1965. The' 70s? Machine lens F= 1:2.8, f=50mm, central shutter between mirrors, speed divided into b doors, 1- 1/300 seconds, X-ray synchronization and self-timer mechanism, double-shadow overlapping ranging, optical viewfinder with extinction device, winding shutter linkage, automatic counting, aluminum alloy die-casting of fuselage. /kloc-0 put into production in 1965, and/kloc-0 completed production in 1969. A total of 1809 aircraft were manufactured. 65,438+0,969 March, supporting the mainland to be handed over to Jiangxi Optical Instrument Factory for production. In 1970s, Dongfeng camera 1969 was designed and manufactured on the basis of 65438+500c SLR camera of Hasselblad, Switzerland. At that time, it was named 6920 (meaning the 20th anniversary of the National Day).

Dongfeng camera

Later, it was changed to Dongfeng camera. Dongfeng camera consists of lens (including shutter), body and back (cassette). Dongfeng has three kinds of lenses: standard lens (f80mm/F2.8), wide-angle lens (f50mm/F4) and medium-focus lens (f 150mm/F4), and the imaging quality is comparable to Hasselblad lens. The lens is equipped with Kangpan mechanical inter-mirror shutter, the speed is B-door,1-1000 seconds, with self-timer and XM flash synchronization, and there is also a depth of field prediction rod on the whole lens, which directly indicates the depth of field distance. EV value data indicator ring, etc. In addition to a set of film winder, viewfinder and ranging device, the fuselage also contains two auxiliary shutters and mirrors, which can be opened and locked at any time. The cassette can be detached from the fuselage at any time and can be loaded with black-and-white and pink films with different sensitivities. Each film box can automatically count and stop films. The main production date was 70 -73, and 97 pieces were produced. Due to the value for money, the production quantity is very small, and it has become the "darling" of world-class collectors. At the auction of China antique cameras held in Singapore, the final transaction price of a Dongfeng camera was 1 10000 yuan. Red Flag Camera This camera was the first German Lycra M3 head-up camera produced in China in 1973, and was named "Red Flag 20". The matching lens of the camera has a standard lens.

Hongqi camera

(f50mm/F 1.4), wide-angle lens (f35mm/F 1.4) and medium-focus lens (f90mm/F2) are all top-quality lenses. A camera baseline double-image overlapping rangefinder is designed by using a high-power bright frame viewfinder. The film winding adopts a fast film loading mechanism, and the highest shutter speed is11000 seconds. On the cover, Mao Zedong wrote "Red Flag" in calligraphy. The main production date was 73 -79, and the total output was 2,765,438+0, which gradually became the object of camera collectors all over the world. According to the Blue Book of Camera Collection Price Guide published annually in the United States, the price of a set of "Red Flag 20" cameras has jumped to 10000 USD. In the 1980s, KJ cameras used a manual mechanical program shutter behind the mirror. When shooting, adjust the EV value adjusting ring by hand according to the specific light conditions. There are 7 adjustable gears on the camera, from EV9 to.

KJ camera

EV 15. lens F = 1: 2.8, f=38mm, sensitivity ASA50 50,100,200. This camera is a camera with small volume, light weight, wide lens angle, reliable structure and simple and convenient use. Production date: 82 -87 KE camera 1983. Based on KJ camera, this machine uses cadmium sulfide photosensitive element to control exposure. It is the first generation photosensitive element in China.

KE camera to control the shutter time. From EV5 to EV 17, due to the stability of electronic components, a total of 16 1 was produced. Edit the description of the reflective camera in this paragraph: Seagull 4A was a famous professional camera in that year, and it still has great practical value. It is more suitable for beginners and movie lovers, and can be used as an entry machine for 120. Component lens: focal length: 75mm；; Finder lens: F2.8 photographic lens: F3.5 (three films, three groups, coated) viewfinder: frosted glass viewfinder; Manual focusing; Parallax adjustment; Shutters from one meter to infinity: domestic inter-mirror shutter 1- 1/300 seconds plus b shutter; There is a mechanical self-timer delay of 8- 12 seconds. Aperture: F3.5-F22 counting: the winding of the rocking shaft is linked with counting; Auto stop, auto count, auto zero frame: take 12 photos with 6X6 frames. Description: there are two kinds of black faces and white faces in the middle period, among which there are more white faces; Advantages of rubber sleeve on focus button 1 Although Seagull looks old, it is more suitable for people who have a fever and love to show off. When you mention 4A, you will have a feeling of vicissitudes. 2. The operation of seagull 4A is very simple for an old hand. 120 film is different from 135 film. The original 120 film is not coincident, so it is easier to rewind the tape like 135 after shooting. 3. Seagull 4A is a 6x6 composition, which seems to be a new field like Hasselblad. This is two styles compared with the digital ratio of 4: 3; In addition, people who take digital photos generally like to shoot wildly, and finally go home and choose a few good ones; 4A You can only take 12 photos, and you should choose each one. 4. Seagull 4A doesn't measure light, so it can only measure light by numbers. Fortunately, the color negative used is more tolerant. 5. Seagull 4A has an intuitive overhead viewfinder. This is more interesting than the paraxial: the viewfinder is dark in a dark place, and the machine has to shoot in a bright direction in a dark place, which is still relatively bright at this time. Compared with Seagull 4A and Seagull 4B cameras, Seagull 4B- 1 camera has the most obvious advantage that the focusing screen is changed to split image. The biggest headache when using the domestic old dual-reflex camera is the "darkness" of the viewfinder, which is not only difficult to focus but also quite eye-consuming, especially for the elderly. In order to take a good photo, besides good lens, good light and good technology, it is also important to focus very carefully. If you want to adjust it, you must look at it first. If you want to look good, you must have a good viewfinder and focusing system. The focusing screen of Seagull 4B- 1 camera is much brighter than that of other dual-reflex cameras, and it will be much more convenient to focus with split images. 6.4A and 4B only have sockets for connecting flashing lights. Seagull 4B- 1 adds flashing lights sockets, which is much more convenient to use. In contrast, 4A only has a socket with a flash cord, so when using the flash, you will feel that your hands and feet are not enough. 7. The image seen by Seagull 4A in the viewfinder is upside down. Taking pictures is very tiring, but you will get used to it later. 8. The images seen in the viewfinder of Seagull 4A are all beautiful, which often makes people want to measure light by half pressing the shutter, thus causing misoperation. Disadvantages of poor edge imaging 9. 120 camera is not obvious. 10.4A has many advantages, such as shaking the handle to pass the film quickly and accurately; In addition, shooting and shutter winding are carried out at the same time, so it is not easy to make mistakes. Most of the time, it is set to F5.61125 and F81125, which can cope with 80% of the cases.
