You've been working as an equipment editor for years, and you're still being sold? This time the old driver turned over。
Do you have any idea how much trouble and problems there are in the actual interior of a well-looking card m6? Let's tell you about this time the director general's maintenance of the "screech" memory。
Teacher chen is our department director and his dream has been to have a card m since he was interested in photography. This year, mr. Chen finally fulfilled his dream of acquiring his own card m6。
Of course, now that the card m6 is out of production, the camera is purchased through the second-hand platform of a certain treasure. The silver m6, which is so beautiful, has become the love of mr. Chen。
Mr. Chen xiao, who owns his own m6, also started his own film. However, the scenery was not long, and the problem was discovered after a period of time: some of the photographs after the sweep would be dark. After excluding the rinsing of the film, the body hardware problem seems to be the only reasonable answer。
And as a camera editor for years, it's basically certain that the camera problem is on the fast door. Naturally, camera maintenance is required. As a result, maintenance tests were conducted with the maintenance master, but a number of problems were identified. The old chauffeur is flipping over。
After testing, it turns out that there are a lot of problems on m6:
1 body skins: replaced, non-original factory skins
Quick door problem: gate b is not operational, speed is not fast
3. Focus: the yellow spots are not accurate enough to achieve precise focus
Photometric problems: photometric components were forcibly repaired by the previous repairer, resulting in the inability to repair the light white spot area
5 . Line frame problem: missing screws, unable to switch the corresponding focus frame
Count it down. Don't look like this card m6 looks good. It's really sick inside. It's not an exaggeration to say that there's nothing wrong with a coke billboard, but there's a little hairy everywhere. In order for his m6 to be able to stabilize his work in the future, the maintenance is going to be complete and complete。
The big bug system will have to be repaired wrongly
After testing, the problem is solved one by one. The biggest problem with this card m6 is light detection, which is the only electronic structure that has a major problem。
And this starts with the light principle and structure of the card m6. Unlike the light system of a modern digital camera, the light of a card m6 is based on the white dot on the fast door curtain (or, to be precise, the front dome), which calculates the light by reflecting the white dot。
The biggest bug in the m6 is the white spot of light which was painted as silver by the former master of hand maintenance. The reflection rate of this light area is actually different from the magnitude of the original white spot. This means that the system is calculating with an erroneous brightness value. Naturally, the light results are problematic。
The electronic system of ↑↑↑徕calm6 is only for light detection, and the fast door components are fully mechanical
As the white dots cannot be repaired, the solution today is simply to make mistakes, and all light calculations are based on the current silver dots. Fortunately, more or less this way to keep the light system going. In terms of precision, stability may not be achieved at the original white dot。
The rest of the card m6 is a yellow spot and fast door problem, as it is purely mechanical, and it is significantly less difficult to repair. Essentially screws, spring processing, replacement of lubricating oil in necessary areas. The restoration of normal precision is generally assured by the necessary conservation treatment。
In short, after this chase deal, there's no major problem with this well-looking card m6. We can continue to use it later。
There's a hole in the old equipment you can't imagine
Second-hand equipment was selected, and is actually a very large market for camera equipment. Not only are modern digital cameras, but the market for medieval film is also quite hot。
But don't look at all the digital camera players who are familiar with contemporary camera devices, but it's time to pick up the old ones. There'll still be all kinds of pits where old drivers turn over。
The problems with the used equipment of the sino-culture can be said to have been demonstrated on this small teacher chen's card m6. Mechanical problems, electronic problems, can occur over time。
Second-hand cameras, especially in the 1980s, may be the largest period of the pit. The age of machines plus the instability of electronic structures can be said to be the most trouble-prone machine period。
And this card m8 was officially born in the 1980s. Fortunately, this card m6 has its advantages. Because the camera's electronic system and mechanical structure are completely separate。
Electronic systems are used only for aerophysical photometry, while camera fast-door systems, focus modules, are purely mechanical and optical. And the greatest benefit of that is that it's broken and it's fixed. Let's split up and deal with one thing。
The fateful card m6
A lot of used camera equipment that looks very new, and the actual situation may not be as ideal as what you see. The repair of the appearance is not difficult for the camera. Rather, the condition of the inner parts of the body is a much more complex and difficult issue。
And second-hand film cameras are actually more difficult. Unlike digital cameras, the body condition can be confirmed by real-time filming. Without a few rolls, the scan is complete and it may not be known whether there is a problem (or whether it is serious) with its own machine。
So it's really more difficult to judge whether a film camera is functioning well than a digital camera. There is no limited use experience or corresponding knowledge reserves. The problem of stepping on a mine does arise。
Many of the camera players are now turning their eyes towards the medium-old film cameras. And the reheating of the film does make more people interested in film production. Just because most of the film cameras are now out of production。
Most of the cameras you buy are used equipment. We can't really just think about digital cameras. The choice for film cameras is no longer to take a picture, or to look at the fuselage as simple as that. We really need to know more about the equipment itself and how it works。
Therefore, if you really want to choose a film camera that suits you, it might be best to consult a real old player。
Especially now digital camera players, simple digital camera shopping logic may not help you in film camera selection. More caution is needed to prevent yourself from being trapped in the choice of equipment。
