5 minutes to teach you to avoid pits. Used cameras are super dry
1. Who is selling used cameras?
personal use: generally, there is only one camera on the homepage because I want to change the camera or idle it, and the others are idle items I have used. Personal use will be more reliable.
camera vendor: there are many cameras on the personal homepage that may be collected from various places. The account dedicated to mai second-hand cameras may be slightly lower than the price of individual users, but camera vendors will renovate cameras to make them look newer, so sometimes they are not credible. If you want to start, you'd better choose a camera that you have used. They can provide detailed camera usage, which is more reliable.
2. What number is not credible?
support counter inspection: counters are mai cameras, and inspection cannot be given. this sentence sounds more credible, but there is no such service.
Inconsistent receipt: One thing to note is that a certain fish has a guarantee time, which is usually 11 days. After 11 days, it will be automatically sent to the other party.
the price of the camera is the same: here, Canon 211D II and Canon m51 II are both 2511, 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 11 days since you received the camera again, and the money was given to the other party, and what you received may not be the camera you took.
3. what camera can't be accessed?
Title Party: The camera description says that it is for the girl's own use/from her ex-boyfriend, generally just to get attention.
The picture of the camera doesn't match: for example, the photo of Canon 851D camera written in the copy is 651D, so the photo is not the real shooting circle of the camera, but found from other places. It is doubtful whether there is a camera with a model machine on it.
Low-priced cameras: Some electronic products such as mobile phones and cameras sold at a very low price because of the dissolution of the crew/the closure of the studio/the switch to clearance, etc. are not credible, and they are likely to be liars.
4. What camera is reliable?
There are only a few cameras: there are only one or two cameras on the homepage, and the others are idle items, so personal use will be more reliable.
Credit level: Look at the credit level and whether there is excellent sesame credit and real-name authentication.
know the camera: if you ask before you start, the other person says that you don't know much about the target and the camera, then if there is something wrong with the camera function after you start, you will also use the ignorance to prevaricate, so it will be more reliable to know the camera.
5. Is the price reasonable?
if you want to know whether the price is reasonable, you can go to multiple platforms to compare > > > Take the second generation of Canon 211D as an example. official website: 4699, JD:￥4398, and a fish: 3511. The brand-new price of Canon 211D is basically above 4111, and the second-hand price is around 3511. If there is fluctuation in 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, side bottom, etc., to see if there are any scratches on the camera, which is probably new.
Accessories: camera accessories generally include shoulder straps, batteries, charging cables, lens covers, etc. Some of them also include memory cards, UV mirrors and camera bags. Please pay attention to the warranty cards, instructions and so on.
shutter times: the shutter has a service life, just like the mileage of a car. The shutter times of a general camera are in the tens of thousands and hundreds of thousands.
camera function: you can chat with the seller through video and ask more about the use of the camera to ensure that all the functions of the camera are normal.
7. how to check the machine?
Video recording of machine inspection process: After receiving the camera, you can record it when unpacking, and if there is any problem, it is also convenient to solve it.
check whether the camera models are consistent: check whether the screws have been disassembled and repaired, check whether there are any big defects in the lower body, and check whether the accessories are consistent with the seller's promise.
video recording of function test process: after confirming that there is nothing wrong 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, check whether the focus and continuous shooting of the camera are normal, cover the lens cover, and turn the brightness to the lowest to take pictures to see if there are white spots; Turn on the camera, turn up the security and see if there are any black spots.
