How many meters do Nikon 70s and 70s need? What should I pay attention to when buying? What accessories does the original have?

According to my personal experience, it is not reliable to buy second-hand cameras in some photographic equipment markets. Although it feels more practical to pay with one hand and deliver with one hand, the dealer will also provide you with a three-day replacement service. However, since we have decided to buy second-hand, we should minimize intermediate links. You know, these second-hand dealers are far smarter than you. They open the door to make money. Under normal circumstances, a profit of 5% must be guaranteed. What worries me most is that the fuselage has been repaired. Such examples are common. Although there are many tutorials on the Internet that teach you how to identify whether it has been dismantled by details such as screws, for some experts, they can leave no trace, and some nearly scrapped fuselage will temporarily resume normal use after simple treatment. However, consumers often fall into the same old habits after buying them home for a few weeks. At that time, they really shouldn't do this every day, they will regret it!

Where can I buy a used SLR? I suggest you go to some professional photography websites and second-hand forums. At present, hummingbird nets and color shadows are mainly recommended in China. These two second-hand forums are very popular at present. Although there are many people posting and replying posts every day, the simple operation interface and powerful search function also bring great convenience to the selection of machines. At the same time, buyers can also compare prices. In contrast, the Hummingbird second-hand forum has more low-end digital SLR models and lenses, and more consumer-grade digital cameras, while the second-hand forum has more high-end digital SLR models and lenses, and the colors and shadows are unscrupulous, and the seller's credibility is high and the transaction rate is relatively high. In addition, because there are many people who know the goods, generally a good fuselage metropolis with good quality and low price will complete the transaction within half an hour after the release.

In addition, there will definitely be netizens reminding you that you can also go to Taobao to buy second-hand goods. Indeed, using the intelligent search system, we can quickly find a large number of second-hand bodies at the right price. However, because Taobao's management of the content department is not standardized, and digital SLR cameras are valuables, many netizens have insufficient experience in buying for the first time, so I don't recommend buying on this non-professional website (professional website, some netizens' posts are very valuable information).

Trading places has confirmed, and the next step is to choose the plane. At present, the choice of digital SLR is relatively large. The best-selling airframes on the market are mainly Nikon D70 and D70s, Canon 350D and 20D and Fuji S3 Pro. Among them, Nikon D70s and Fuji S3 Pro can still buy new products in the market, while other models are outdated products. In terms of price, Nikon D70 has been on the market for a long time, the shutter times are around 1000, and the normal price is around 2800-3000 yuan. The normal price of Nikon D70s is about 3500-3700 yuan, and this machine has a high cost performance, especially when Nikon D50 stops production and the price of D80 remains high.

How to choose second-hand models?

The current price of Canon 300D is only 2500 yuan or even 2200 yuan, but I personally don't recommend buying it. On the one hand, many Canon 300ds currently on the market are second-hand; on the other hand, the shutter has been used more than 30,000 times. Even if you buy it, 700 yuan will be used to change the shutter after sale, and other parts will not be used for long. At present, 90% of the new price of Canon 350D is basically around 3,200 yuan, which is basically the final transaction price, and the cost performance ratio is obviously not as high as that of Nikon D70s. It is said that Canon 20D is the hottest. 20D, as the most comprehensive and technically mature vehicle in the middle and high-end market at present, is not low in positioning but not high in price. 90% of the transaction price in the second-hand market is around 5350-5750 yuan.

For the choice of second-hand models, my opinion is not to start too low and not to pursue too cheap. Since we decided to sell it, we should try our best to move closer to the middle-class digital SLR model and take a long-term view. If the funds are abundant, the first choice is Canon's 20D, followed by Nikon's D70s. In terms of price, don't be too cheap. There is a saying in China: Cheap goods are not good, especially electronic products. It is best to search in the forum for the transaction price of the fuselage with similar model and color in the past month, so as to know fairly well, so that bargaining with the seller will have a bottom.

The price of second-hand SLR is directly linked to the quality of the camera. The so-called 990% new means that the appearance is almost brand new, unused, the packaging is original, there is no damage, and there is no shortage of accessories and invoices. Although there are many such machines on second-hand forums, the prices are generally very strange. Usually, 95% of the products are new, but there is no trace of use. The shutter has been used less than 500 times, and there are many packages, accessories and invoices, and it must be guaranteed within the warranty period. This is very important. 90% of the time is usually around June-1February, the shutter times are less than 3000 times, and there are slight scratches on the appearance, but there must be no paint peeling and damage. You must have a warranty card and an invoice to guarantee the warranty. Externally, 85% new paint is usually defined as slight paint loss. Just after the warranty period, the shutter frequency is about 8000 times, and the accessories are complete. If it is 80% new, the shell has obvious traces of use, the shutter is used about 15000 times, and the camera must be maintained for 2 years. 70% new, usually the camera has a maintenance history, the function is normal, the shell is complete, and the imaging is no problem. As for the imaging problem, or the key has been seriously out of order, there is no purchase value. Some cameras have used their shutters more than 30,000 times. I don't recommend buying this kind of machine, especially the low-end digital SLR camera, because it is close to the design life of the camera itself.

Second-hand camera transaction process:

Because online transactions can't be like offline transactions, you can only judge the quality of the camera by pictures and sellers' descriptions. This usually requires the seller to take a group of photos of the front, back and top of the fuselage, with a larger resolution, preferably 1024X768, so as to enlarge. In addition, the seller also needs to cover the lens with the lens in his hand, adjust the aperture to the maximum, adjust the shutter speed to the slowest, take a black photo at the maximum ISO sensitivity setting and send it to you, and test the CCD bad point with DEADPIXEL software. Finally, let him take a white photo and some life photos to roughly judge the imaging situation of the camera. In this way, the part that can be detected online is completed. Finally, confirm with the seller whether the accessories are complete and whether the battery is original. If not, the price can be further discounted. In addition, it is best to have a telephone conversation with the seller after the transaction is confirmed.

The next step is to make a deal. There are three common trading modes in green camp Wuji and Hummingbird.com. The first is Alipay, which is also the safest payment method at present, and it guarantees the interests of buyers and sellers. I won't talk about the specific process here. Just look at the picture below:

Second-hand camera transaction process

However, because there are some older photographers among the people who play photography, they don't often surf the Internet or are uneasy about using bank cards online, so they will adopt the intermediary model. From the transaction process, the intermediary model is very similar to Alipay, but it has two shortcomings. First of all, the transaction cycle is relatively long, which is inevitable, because many processes are manual operations. Secondly, there is a certain handling fee. Of course, this fee is not charged by the website, but by bank transfer (Alipay may charge a fee for off-site transactions after February 2007). In addition, some users will choose to pay before receiving the goods, which is based on trust. One is to look at the registration time of the other party's ID, the other is to look at the other party's previous comments in the forum, and the third is to look at the seller's previous transaction records. I don't recommend this trading mode for beginners.

About the choice of courier company:

If it is a long-distance transaction, special attention should be paid to the choice of courier companies. Although there are many choices in the domestic freight market at present, well-known companies such as Datong, Tong Yuan, Shentong and SF have certain advantages in terms of price and speed, but for valuables like digital cameras, I suggest using postal EMS (asking the other party to quote). Because the insurance company in the postal company will bear the compensation according to the insured amount, which is what we often call the quotation, most social express delivery companies are vague about the quotation and the terms are too overbearing. Once the goods are lost or damaged, it is difficult to get compensation, and even some reputable express delivery companies have an upper limit of only 5,000 yuan. So EMS is a little expensive, but safety, safety first! As for the postage, you can ask the seller for the postage when you make a counter-offer, usually around 40 yuan. After receiving the goods, be sure to check whether the package is in good condition in front of the EMS deliveryman, and try to unpack it before signing for confirmation of receipt.

At this point, the online transaction is basically over, and our buyers can test the performance of the camera with their own lenses and check the details of the camera. Generally, they can delay one day and use the functions of the camera all over. If it is basically similar to the seller's description (usually the seller exaggerates), you can inform Alipay or the website intermediary to pay the other party. However, if the camera color is found to be quite different from the seller's description, you can go through the return formalities. Generally speaking, you will lose 30-50 yuan's courier fee.
