What are the camera connection conversion accessories?

When it comes to cameras, everyone is familiar with them. It has become a necessary electronic product for everyone. Then the popularization of camera connection conversion products, such as data cable, charging cable, USB cable, camera lens adapter ring and so on. Here, the purpose, key points and precautions of several camera connection accessories are briefly introduced. Camera parts daquan

1, memory card

Usage: independent storage medium, used to store all the data in the camera and the necessary accessories in the camera.

Key points of purchase: There are many types of memory cards, so you should know the requirements of the models you buy before buying. In addition, merchants will recommend consumers to buy high-speed memory cards, because high-speed cards are expensive and the profits will be higher. In many cases, such performance is not required for general use.

Usage: put the memory card into the special card slot of the memory card in the camera to use.

Step 2: tripod

Usage: professional photographic equipment, used to stabilize the camera and achieve a certain photographic effect.

Key points of purchase: pay attention to the material of tripod, which can't be used for a long time in general. There are many kinds of tripods. In the process of purchasing, you should buy the corresponding tripod products according to your own needs.

Usage: spread the three legs of the tripod to keep it stable, open the plate buckle on the foot tube, adjust it to the height you need, and then buckle the plate buckle. Open the knob next to the handle, adjust the handle to a suitable position, and then fix the knob. Adjust the level, unscrew the knob below, and adjust the bubble on the level to the middle position.

3. Ultraviolet color filter

Uses: one is to protect lenses, and the other is to filter light.

Key points of purchase: pay attention to the logo of UV mirror. Different logos have different effects. When purchasing a UV mirror, it should be noted that the installation of the UV mirror can not produce a color cast effect on the photos taken in normal environment, and the wide-angle end, especially the telephoto end, can only be clearly focused after the camera is equipped with a filter. If UV mirror is not plated to enhance transparency, its transmittance is only 90%. Ordinary UV mirrors are double-sided and single-coated, and the light transmittance is about 96%. In addition, there is a multi-layer coated MCUV mirror, the transmittance of which is as high as 99.9%, which is much better than the ordinary UV mirror and can completely retain the characteristics of the original lens.

The way to identify the quality of UV should be to use a UV mirror as a mirror on a black background: what can't be illuminated is a good UV mirror; UV mirrors that can reflect their own shadows are all low-grade. The clearer the shadow, the worse the lens and coating. This is because the lens with high transmittance, the light is transmitted and not reflected at all, so nothing can be seen. If there is no black background when you buy it, the easiest way is to look at the lens as a mirror and then press uv. You can hardly see your face before installation. If your face appears clearly after uv, it is fake.

Usage: Install the filter on the camera lens for use.

4. Cable release device

Purpose: To control the remote control line of shutter, and take photos, exposure and continuous shooting remotely.

Key points of purchase: it is recommended to buy the original factory, and the cable release within 100 yuan should be carefully selected! Wires and plugs must be carefully selected! The inferior line will harden above zero and become a stick between you and the camera, which will interfere with your shooting stability! Inferior brands and businesses should stay away! Time-delayed shooting, no noise.

Usage: First, set up a tripod. If the wind is too strong when shooting, you can fix the tripod with heavy objects.

Take out the camera, put it on, and fix it. Next, take out the wireless receiver and the connecting cable and connect it to the camera: plug one end of the connecting cable into the wireless receiver and the other end into the camera shutter link port. After the wireless receiver is connected with the camera, it is hung on the camera with the hook on the wireless receiver to fix the wireless receiver. After connecting the wireless receiver with the camera, turn on the camera, adjust the camera to M, and adjust the ISO to manual. Take out the wireless transmitter and press the arrow keys to debug. Set the delayed shooting time to 3 seconds and the interval time to 3 seconds. Move the arrow keys to set the number of shots to 100, and then press the start/stop key. The camera will shoot according to the set program. In the process of shooting, if you want to stop shooting, just press the start/stop button for timing, and then press the shutter button to stop shooting.

5. Shutter remote control

Usage: You don't need to press the shutter button on the camera. After the link between a receiver and a transmitter and the hot boots on the top of the camera, you can realize the camera shutter function through the button on the transmitter.

Key points of purchase: whether the wireless remote control camera is sensitive, and also check whether the fixed lock can be clamped. Pay attention to the material and workmanship of the products. Different materials will directly affect the quality of products.

Usage: First, we connect the base of the receiver with the hot shoe seat, then insert one end of the connecting cable that conforms to the model of the camera to be connected into the receiver, (wireless shutter controller can skip this step) insert the other end into the transmitter, turn on the switch between the receiver and the transmitter, and then press the shutter button of the transmitter to realize the camera shutter function.

Step 6 deal with

Usage: camera accessories installed at the bottom of the camera, built-in vertical shutter button and other operation buttons, improve the grip performance. Some handles are also equipped with multifunctional battery boxes to support charging the camera at any time.

Key points of purchase: choose a well-known and reputable agent manufacturer. Choose manufacturers with more after-sales service outlets. Choose your own brand and model of special camera handle, so that the performance will be more stable. Compare several manufacturers to find the best cost performance, and the best products have been evaluated by professional institutions. Don't look for low prices. Those with low prices may have quality problems.

Common problems and solutions of digital camera connection

1. How to charge the camera with the power cord?

(1) Find out where to put the battery. SLR cameras have many slots, such as memory card slots and batteries. Each SLR camera model may be different, but basically the battery is placed at the bottom of the camera (there will also be graphic labels in the general manual).

(2) Open the cover, take out the battery and find the slot. Of course you need to take it out. First of all, according to the schematic diagram of the cover, push the switch of the cover, open the cover, and then pull the white thing, the battery will pop up naturally, and we can get it.

(3) Put it into a matching charger. After you take it out, it is charged, which is very similar to the battery of a mobile phone. Generally, everyone buys a camera, and there is a charger in the package, so it must be matched. Otherwise, you can't put it in for charging. When inserting, pay attention to the electric sheet. They should completely overlap.

(4) Pay attention to the identification of charging. When you start charging, most SLR chargers will have a reminder light, which will flash fast and slow (with different frequencies), and then you can see how much charge is charged. Just like a cell phone battery, it will turn green.

(5) It is recommended to have a spare battery. Everyone went out to take pictures, sometimes they had a good time, took a lot of pictures, and then the power went out. It may be in the wild, where there is no charging, so it is best to have a spare battery, 2 or 3. Then basically, it will be fine one day.

(6) Reduce the screen brightness. However, there are many artificial ways to save the power of the camera. For example, the brightness of our LCD screen can be darker and we can watch less. Many people delete it after filming, and the LCD screen is always on, which consumes a lot of power.

(7) Pay attention to the remaining battery power at any time. When shooting, we can always see how many batteries (left) have shoulder screens, just look directly. If not, open the LCD screen, find the menu to view the battery information, and it will be displayed.

2. How to connect a computer with a camera USB cable?

(1) The SLR camera is connected to the computer. Of course, there is also a data cable, which is provided when buying a camera. There is a special socket on the camera for the data cable to be inserted, and you can link any usb interface on the computer at will. Generally speaking, the camera should be set to the on button so that the computer can recognize it.

(2) Don't forget to unplug the data cable after the computer is connected to the camera, and don't suddenly stand up and cause the data cable to be violently pulled. This situation is not uncommon. In many cases, the data cable will not be broken, but it will lead to the oblique damage of the data connector.

(3) Camera lens adapter ring

When taking pictures, you can use the adapter ring to add various filters to protect the lens or increase the artistic effect, or you can add extra lenses to extend the focal length and increase the wide angle.

3. Precautions:

(1) Because the old lens often has no contact, the camera doesn't even know there is a lens. Even if some adapter rings have contacts, no one can guarantee that the lens data can be accurately transmitted to the camera. Therefore, when using the old lens, the photometric value is only reference data, so you don't need to believe it. If the automatic exposure is not accurate, you may wish to use manual exposure.

(2) When choosing the adapter ring, don't be greedy for cheap. Some knockoffs have poor compatibility and stability. After connecting the camera, the camera may have an information error and crash. In addition, some inferior electronic adapter rings may have problems such as scratching the fuselage, incorrect contact position, chip bending and lens sticking, and the consequences are very serious.
