How to choose a home DV camera

Lead: Generally, it is expressed by definition, that is, the number of TV lines that can be distinguished on the screen, which can be divided into horizontal definition and vertical definition. The index gives the clarity of the central part. Products must be inspected in place, especially when the purchase price is obviously lower than the normal market price. But usually there is one on the camera? Tear it up? Many engineers are worried about this label. We suggest you buy big brands and buy them from authorized regular dealers. In addition, it can be disassembled randomly in batches to check the brand and size of CCD.

How to choose home DV camera 1? Check the optical viewfinder and LCD screen, don't turn on the power first, first visually check whether they have scratches and abrasions, and see if there are many handprints, indicating that someone has used them before; Then turn it on and check it again to see if there are any bad spots on the LCD screen, whether the color is saturated and natural, and whether the image is clear.

2. Check the shell of the mini DV for hard scratches and paint peeling. If there are these phenomena, it may indicate that someone has used them before or bumped into them during transportation. You'd better find a dealer to change it.

3. Check the optical zoom lens and press the zoom switch several times alternately from T (telephoto, longest focal length) to W (wide angle, shortest focal length). At this time, you should hear subtle, subtle? There is continuous mechanical operation sound, and the monitoring picture on the LCD screen should change uniformly from large to small or from small to large. If the sound of mechanical operation is not delayed and the monitoring picture is not jumping or shaking, it indicates that the performance is good.

4. Check the focusing performance of the lens, aim the lens at something nearby, such as a pen on the desk, to see if it can focus quickly and smoothly, and then enlarge the optical zoom to see if it can focus quickly and smoothly. If the smooth focusing of close-range objects is slow and laborious, it is recommended that you do not buy such DV.

5. Check the basic video recording function, put the DV tape into the DV player, start the DV player, fast forward and fast backward to see if it can advance and retreat freely, then record the surrounding environment for a few minutes, then stop and play back the video just taken to see how the playback effect is. If you see the playback image as clear, delicate and bright as the shot image, and the picture is stable, it means that the recording and playback function of this DV is normal. We must pay attention to this. After all, the recording and playback effect is what we care most about!

6. Check the accessories of mini DV, and carefully count the random accessories indicated in the manual, so as not to find something missing when you buy it back, and you have to go back and ask for it, which will bring a lot of inconvenience.

7. Carefully verify whether the product serial number on DV is consistent with the serial number on the packaging box.

8. Buy other accessories

Battery: You need to buy a spare battery. You need to buy two more batteries to increase the shooting time as much as possible. In addition, you must carefully look at the capacity after buying a large-capacity battery.

DV tapes: I need to buy some DV tapes. How many boxes to buy according to your own needs, the price is not expensive. I suggest buying more boxes so as not to run out later and have to buy more.

IEEE 1394 acquisition card: You need to buy an IEEE 1394 acquisition card, otherwise you can't collect it in the computer. You don't need to buy a good one, just a normal one. 150 yuan will do it.

Memory card: The memory card that comes with it is generally only 8MB or 16MB. If you think the capacity is small, you might as well buy a larger memory card, such as 64MB, 128MB.

UV mirror and polarizer: It is best to buy UV mirror and polarizer, which add up to about 300 yuan. UV mirror can usually protect the lens, and polarizer can improve the shooting effect. It can darken the sky and highlight the clouds, which will be filmed for tourism? Add color? Quite a lot.

Tripod: If you need to buy a tripod, you should buy a sturdy tripod with a height of about 1.5 meters, because this height is convenient for the photographer not to look up.

Camera bag: You need to buy a camera bag. The principle is that you can put your mini DV, several DV tapes, power cords, spare batteries, UV mirrors and polarizers, and some other accessories. The lining of the camera bag is preferably sponge or flannel, because this can effectively reduce the impact caused by violent shaking, thus avoiding damaging the DV.
