2. Check the number: Next, let's take a look at whether the body model on the digital camera shell belongs to the product model sold in Chinese mainland market. For the specific product models sold in Chinese mainland market, you can consult at the local digital camera special maintenance center or directly call the service hotline of the digital camera manufacturer. Take Canon (HK) as an example: Are people afraid to buy parallel goods (mostly Hong Kong goods) when buying Canon cameras? There is a way to tell them at once. Enter the serial number of the camera at the following website. If "Sorry, please correct this serial number" appears, then what you bought should be licensed.
3. Physical examination: Let's check the body of the digital camera carefully. For example, first check whether there are scratches or other damages on the surface of the fuselage, and then open various covers as much as possible to check whether there are old traces or scars inside the camera.
4. Physical examination: After the appearance inspection is completed, the digital camera can only work with a battery, so that the lens, screen, reflector and other optical equipment and imaging equipment of the digital camera can be inspected. For example, take off the fuselage cover, look at the light through the observation window to see if there is obvious dust on the focusing screen, and carefully look at whether the reflector is in good condition.
5, looking at the mirror: carefully check the lens. As the lens is the most important part of the digital camera, its quality is directly related to the overall performance of the digital camera, so the inspection of the lens is a very important link to identify parallel cameras. When checking, you should first remove the front cover and back cover of the camera, and turn the aperture to the maximum to see if there is any abnormality and excessive dust behind the lens. Then look at the surface of the lens from an oblique direction under the light to see if there are scratches or other things that should not appear. Operate the focus ring and aperture ring again to see if there is any abnormal looseness. Finally, take a closer look at the screws on the mirror. If there are obvious scratches on the screw, it is very likely that the lens has been removed.
