Maintenance method of SLR camera

Many photographers now have their own SLR cameras, but sometimes SLR cameras break down. Do you know what the maintenance method of SLR cameras is? The following is what the maintenance method of SLR camera is for you, I hope it will be useful to you!

Maintenance method of SLR camera

1, light maintenance: (It can be completed within one hour) For example, replace the LCD screen, replace the screen cable, repair the card slot of 1394 interface, and replace and clean the CCD. Non-startup problem (non-water power supply problem), preliminary judgment and quotation of machine failure, some simple lens failure, replacement of shell parts.

2. General maintenance: lens replacement (completed within two hours), lens mechanical fault maintenance, non-startup fault maintenance, camera replacement.

3. Complex maintenance: serious water inflow and damage, difficult fault maintenance, camera maintenance with warehouse, and broadcast camera maintenance. Replacement parts need to be ordered.

Maintenance method of SLR camera

Maintenance and cleaning of lens

The lens is the most critical and fragile part of the camera, so when using the camera at ordinary times, we should pay great attention to the protection of the camera lens, and don't get contaminated with dust easily, and don't let the lens be "dirty" by dirty hands. Only when it is absolutely necessary should we clean the lens. When cleaning, it is best to blow off the dust with a balloon or gently brush it off with a soft brush. If you encounter stubborn dust, you must gently wipe it with special lens cloth or lens paper. Remember not to use soft-looking paper such as paper towels to clean the lens, because these papers contain wood pulp that is easy to scratch the coating, which will seriously damage the key coating on the camera lens.

Protection of LCD screen

Color LCD screen is easily scratched by hard objects, especially the color LCD screen without protective film is more fragile. Any scratch will leave a permanent mark, so you can consider sticking a protective film on your PDA or mobile phone when using it, which has a very good effect on protecting the color LCD screen. In addition to preventing scratches, special attention should be paid to avoid the damage of high temperature to color LCD screen. As the temperature rises, the color LCD screen will turn black. After reaching a certain temperature, even if the temperature drops to a normal state, the color LCD screen cannot be restored, causing irreparable losses.

Use and maintenance of batteries

Digital cameras are different from traditional cameras. Digital cameras have a great demand for electricity, so SLR cameras generally use nickel-hydrogen batteries or lithium batteries as power sources. Ni-MH battery will produce memory effect, reducing the total capacity and service life of the battery. As time goes on, the stored charge will be less and less. Therefore, try to use up the power before charging. The memory effect of special lithium battery is almost negligible, so special attention is not needed.

In addition, attention should be paid to maintaining the integrity of the battery insulation. Once the damage is found, stick it with transparent tape. Always check whether the electrode of the battery is oxidized, and wipe it clean if it is slightly oxidized. When serious oxidation or falling off is found, the battery should be replaced immediately to avoid damage to the single-lens reflex camera caused by battery leakage and other faults. In addition, when the digital camera is not used for a long time, the battery must be removed from the digital camera or charger, completely discharged, and then stored in a dry and cool environment.

Travel protection

Protect the lens with the lens cover, put small equipment and accessories in the bag and hand, and separate them with certain soft objects to ensure that they will not collide with each other. Especially the easily damaged equipment, it should be wrapped with a layer of soft things. When flying, the damage degree of metal detector is slightly less than that of baggage detector. If necessary, manual inspection can be required to minimize X-ray damage.

Long-term preservation of digital cameras

When the digital camera is not used for a long time, we should pay attention to the maintenance of other parts and accessories besides the important parts such as the body and lens. The camera and holster should be placed separately to prevent the moldy holster from affecting the camera. Parts such as shutter and self-timer that have been tightened in the camera should be loosened to avoid damage caused by fatigue of these parts for a long time. The lens aperture should be set at the maximum gear and the focusing distance should be set at infinity. If it is a camera with a dual focal length lens or a zoom lens, the extended lens should be retracted to its original position and then put into a storage container that can be kept dry.

Disadvantages of SLR cameras

1, which is bulky and inconvenient to carry.

Because the mirror and pentaprism of SLR camera are essential, the body can't be smaller. In order to ensure the firmness, materials can not be saved, which determines that it can not be more ideal in weight and volume. A huge camera that is too conspicuous will even affect the mood of the subject when shooting humanistic subjects, which is too easy to give people a sense of depression. Carrying is also a problem.

2. Mechanical vibration and noise

When the reflector works and the shutter curtain is opened and closed, most SLR cameras are noisy and cannot be used in some quiet environments. Especially the vibration of reflector, even if there is no external force, its own vibration will affect the image quality. If you want to avoid vibration when shooting night scenes, you should open the reflector for pre-lifting, so as to avoid the picture shaking when the machine vibrates.

3. What you see is what you get.

Because framing is through the lens, although what you see is what you get, framing is also restricted by the lens, and the brightness of the field of vision is greatly affected by the lens. When using a lens with a relatively large maximum aperture, the viewfinder may be brighter, but when using a lens with a relatively small aperture, the field of view will be darker.

4, the operation is complicated

There are too many functional parameters for professional cameras to set by themselves. Although the entry-level SLR has added a lot of fool modes, which has solved the threshold problem of using SLR well, it is obviously a waste for SLR cameras to use only fool modes.

5. A large amount of capital investment in the later period.

Some friends have macro function when using small digital cameras, and usually shoot flowers and plants, but after using SLR, they have to buy a macro lens to realize those. Some manufacturers' SLR bodies are not anti-shake, and anti-shake needs to be realized on the lens. Buying a lens with anti-shake function increases the cost.

6, need to pay special attention to cleaning and maintenance.

It is good to replace the lens, but if you are not careful, there will be dust in the fuselage, which is likely to fall on the photosensitive element. If you forget to clean it, the photos you take will have a lot of dirty spots. Related necessities are also expensive. With a SLR, of course, you need a sturdy tripod, and a set of sturdy domestic tripods costs about 1000 yuan. A good lens should be matched with a good UV mirror. According to the shooting subject and shooting conditions, it is also necessary to equip accessories such as polarizers and reducers. Backpacks should be stronger, too. Good quality backpacks are more expensive.

To sum up the above points, it can be concluded that it is more reasonable to use a small digital camera if the lighting environment is not harsh, if you don't require extremely high image quality, or if you are afraid of affecting the conditions of the subject. As an ordinary photographer, the choice of image quality and portability determines the direction of choosing a camera. In fact, the best camera is the one that suits you best.

Therefore, some foreign journalists picked up cameras with head-up framing and double-image overlapping focusing. They think this camera is small and light, with bright view, quick focus and easy to capture.
