They were sold as personal collections and not collected from xx. These tests are carried out before shipment. New and unused items made several decades ago do not amount to new and unused items now being produced and are carefully purchased by those who seek perfection. Questions, if any, should be answered in detail before the purchase (preferably by letter). The items are sent out without change and have no energy or time to return。
Please take a good look and make the order. Thank you。
The early mechanical self-censorship is more tender, and it is recommended not to be used frequently! When the door is stringed, the string wrench is to be taken to the bottom and the key card avoided. There's a light power switch。
Background information:
In 1959, the development of our 135-symmetric camera began to bear fruit, with the testing of the morning camera at the tianjin camera plant, the testing of the purple mountain camera at the nanjing camera plant and the testing of the ceiling camera at the jilin chang chun optical institute. For technical reasons, the failure rate is high, it is difficult to use properly and cannot be scaled。
The early 1960s were a turning point in our 135-single anti-cam industry. – the successful development of the df135 single-photo camera in shanghai, which has laid the foundation for our 135 single-photo camera industry, with a total output of over 200。
In 1964, the shanghai camera plant exported its products and registered its trademark seagull, after which all products produced by the plant were branded seagull。
Following the successful development of the shanghai df135 single-photographic reflector camera at the shanghai camera plant, in 1966 it was modelled on the successful development and production of the df135 single-photographic reflector camera for seagulls, b, 1-1/1000 seconds. The roof of the machine, as well as the oxen pellets, designed the sky-sliding icon for the sun background sea, with mechanical self-censorship and retroscopy pre-upgrading features, with single and 10,000 flash-light holes on the right side of the body, and a lens of six four sets of double-higher film 58 mm f2, class vii。
Seagull df135 single-photo camera was exported by china light industries import and export company at a price of £50。
In 1969, the shanghai camera headquarters improved the seagull df single camera, and developed the df-1 single camera:
1. The viewer is replaced by a fennel lens with lightweed to facilitate manual focus。
2. The cold boots on the roof are replaced with hot boots to facilitate the use of off-board flashlights。
3. The bottom opening button is replaced by a spin-in-the-barrel plug lock, which is easy to operate。
4. The film track increases the steering wheel and avoids the tilting of the film。
5. The lens focus rings are converted to rubber-crushed casts with comfortable hands。
The lens cap has been changed to a button card mouth and is easy to use。
7. Change the view window to rectangular, easy to view, large, beautiful。
8. The fast-gate velocity adjustment instruction was changed to a 45-degree mark, which is easy to observe。
In november 1971, the machine was placed on the market, and its early name was type 102, so it had 102 words in its body number。
In 1981, the shanghai master camera plant improved the df-1 single camera for seagulls and developed the df-2 single camera for seagulls。
In 1985, the shanghai camera headquarters improved the df-1 single camera for seagulls and the df-102a single camera for seagulls and developed the df-102b single camera for seagulls。
From df to df-1etm, the gulls have been walking for 20 years. In the 1980s, when the world's cameras were rising, and we were still in the era of seagull df and its various imitations, the jiangxi optical instrumentation plant was the first to break the situation, and the development of jg303m began in late 1970, producing only a few prototypes because of the high technical standards, but the national production camera entered the era of ttl measurements, and the seagull df-1etm single camera was born against this historical background. The early version of the single-photo camera of the seagull df-1etm was interesting, with the lens pole being self-contained, and the link to the body was located at four o'clock at the front。
As a result of a strong consumer response, the "editor's note" of the practical df-1etm report published in the sixth issue of popular photography in 1988 published a letter from the deputy director of the shanghai camera general: the introduction of the special card is a technical problem, the factory is closing, and the df300 card will be changed to an etm card after absorbing the technology of minoltax300 and fully introducing df300
However, instead of introducing the df-300 of the etm pass, the shanghai camera headquarters introduced the later version of the df-1etm, which is fully compatible with the minoltamc/md card pass, and increased the optical power source switch。
It's not because they're good at their performance, but because they're looking for the distant memories and the joys of the memory。
