Five minutes to teach you to avoid the pit. Used cameras are super dry goods.

1. Who is selling second-hand cameras?

Personal use: there is generally only one camera on the homepage because I want to change the camera or leave it idle, and the others are all idle items I have used. Personal use will be more reliable.

Camera manufacturer: There are many cameras on the personal homepage that may be collected from various places. The account specializing in second-hand cameras may be slightly lower than the price of individual users, but camera manufacturers will renovate the cameras to make them look newer, so sometimes it is not credible. If you want to start, you'd better choose a camera you've used. They can provide detailed camera usage, which is more reliable.

2. What figures are not credible?

Support counter inspection: The counter is a mai camera, so it is impossible to inspect the goods. This sentence sounds credible, but there is no such service.

Inconsistent receipt: It should be noted that a certain fish has a shelf life, which is generally 10 days. 10 days later, it will be automatically sent to the other party.

The price of the camera is the same: the second generation of Canon 200D and the second generation of Canon m50 are both 2500, which is not credible.

So if the camera you took is not the same model as the camera you received, and the other party asks you to return it and reissue it, it may have been 10 days since you received the camera again, and the money was given to the other party, but you may not have received the camera you took.

3. What camera can't get in?

Title Party: In the camera introduction, it is written that girls are for their own use/from ex-boyfriends, generally just to attract attention.

The camera pictures don't match: for example, the photo of Canon 850D camera written in the copy is 650D, so the photo is not the real shooting circle of the camera, but found from other places. It is doubtful whether there is a model machine on this camera.

Low-priced cameras: some electronic products such as mobile phones and cameras sold at very low prices because of the dissolution of the crew/the closure of the studio/the change of occupation. , are not credible, and a high probability is a liar.

4. What camera is reliable?

There are only a few cameras: there are only one or two cameras on the home page, and the others are idle items, so personal use will be more reliable.

Integrity level: look at the credit level, sesame credit is excellent.

Know the camera: If you ask before the start, the other party says that you don't know much about the object, then if there is something wrong with the camera function after the start, you will also use the ignorance to prevaricate, so that knowing the camera will be more reliable.

5. Is the price reasonable?

If you want to know whether the price is reasonable, you can compare it on multiple platforms >>& gt Take Canon II 200D as an example. Official website: 4699, JD:￥4398, and a fish: 3500. The brand-new price of Canon 200D is basically above 4000, and the second-hand price is around 3500. If there is fluctuation within this range, it is basically normal. If it is much lower, it is not credible.

6. What do you need to know about cameras?

Body color: Look at the photos of the camera, including the front, back and side bottom. See if the camera has scratches, it is likely to be new.

Accessories: Camera accessories generally include shoulder straps, batteries, charging cables and lens covers. Some also include memory cards, UV mirrors and camera bags. Pay attention to warranty cards, instructions and the like.

Number of blinds: blinds have a service life, just like the mileage of a car. Generally, the shutter times of cameras are in the tens of thousands to hundreds of thousands.

Camera function: You can chat with the seller through video and ask how to use the camera to ensure the normal functions of the camera.

7. How to check the machine?

Video recording of inspection process: after receiving the camera, you can record it when unpacking. If there is any problem, it is also convenient to solve it.

Check whether the camera model is consistent: check whether the screws have been disassembled for maintenance, check whether there are any major defects in the fuselage, and check whether the accessories are consistent with the seller's promise.

Video recording of function test process: after confirming that there is no problem with the accessories of the camera model, you can test whether the buttons of the camera are normal. Check whether the lens is installed smoothly, whether the focus ring and zoom ring rotate smoothly, whether the turntable, dial wheel and button of the camera are used normally, whether the focus and continuous shooting of the camera are normal, cover the lens cover, and adjust the brightness to the lowest level to take pictures to see if there are white spots; Turn on the camera, turn on the security guard and see if there are any black spots.
