How do you buy a Canon SLR camera to see if it is a new machine that has just appeared Not a prototy

The shutter count speaks for itself, and of course, there are unscrupulous merchants who modify the data, but the difference between a new machine taken out of the box and a prototype that can be manipulated casually in the mall is still very obvious.

For example, whether there are wear marks on the metal of the lens mount, whether there are fingerprint marks on the back screen, whether there is dust on the surface of the machine, whether the time and date should be adjusted when the machine is turned on (the first time the new machine is turned on must be adjusted), it is best to call a knowledgeable friend to accompany you to buy, and choose a good reputation and reputation when choosing a business.

The number of shutters... Or open it to see if you want to adjust the time, and the new machine has to adjust the time.

If you want to buy it, just ask the salesperson to bring you the unopened machine.

In order to prevent the average person from just looking at it and not buying.

Usually, I will show you a prototype first.

Premise: If you're going to buy it.

It's best to take a new machine unopened.

To put it simply, it can be summed up in 4 words: "careful observation":

1. Observe the tamper-evident seal of the outer packaging, if it has been torn, it is definitely not a new unpacked;

2. The wear and tear of each interface part of the camera, such as the contacts of the lens and the battery, the new machine should have almost no or very few traces of quality inspection;

3. Whether there are fingerprint traces on the lens;

4. The appearance of the whole camera, the new and the sample are actually quite different, even if the whole machine is cleaned and refurbished, there are still some parts of the dust that are not easy to remove, such as the inside of the strap hole, etc.;

5. The shutter number can also be used as a reference, of course, the brother above said that now you can use the software to brush;

6. It is best not to buy a camera that is about to be withdrawn or has been on the market for a long time, because the probability of this machine being repaired and refurbished will be much greater, and there are fewer problems in this regard for new models.

Confirm the Canon SLR you just bought.

Isn't it brand new and the method is as follows:

1. Visual identification of anti-counterfeiting labels.

The six characters of the new label "China Licensed" are laser positioning, hot stamping with a white effect, so that the hands are aligned. And use the glide letter laser to type out real English words, and observe the rainbow effect from different angles.

2. Anti-counterfeiting label *** scanning query.

3. Visual identification of RFID anti-counterfeiting labels.

You can tell by the hologram color change in the bottom right corner of the entire label. When viewed from the front, it appears red, and when you change the angle, it turns green. If there is no change in the color of Yan Fangchang, it will be replaced by Non-Canon (China)**.

4. Visual recognition of old 16-digit coded anti-counterfeiting labels.

The four-digit security** on the surface of the anti-counterfeiting label of the purchased product can be directly compared to the four-digit security** on the adhesive layer. If consistent, it's normal. If not, it's not Canon (China).

5. Security label communication and inquiry.

You can sell products by comparing labels by calling customer service directly (checking the 16-digit security code only after the four-digit color, product category, and initial inquiry time).

It can be judged by the color change of the hologram in the bottom right corner of the entire tab. When viewed from the front, it appears red, and when you change the angle, it turns green. If the color does not change, it will be sold by non-Canon (China).

In my experience, I won't copy it. Hope it helps.

First of all, check the manual to see if all the accessories are complete.

Then check the serial number of the body to see if it is licensed.

Check the body for scratches and the battery for scratches.

Take down the lens and look inside the fuselage to see if there is any dust or scratches on the image sensor.

Take a picture of the all-black ** and see if there are any dead pixels in the CCD or CMOS.

By the way, see if your machine's shutter count is 0.

If none of the above is a problem. I don't think there's any major problem with your machine.

When you get a new machine, you need to use it a lot and operate it a lot.

Duo Burn let read the manual, it is your best teacher.

Familiarize yourself with each function and use each function key for the roll key.

Use more to confirm whether this machine is good or not. Hehe.
