Canon SLR photography primer

1, invincible rabbit is the most powerful professional-grade SLR in the same price, and it is irreplaceable. However, in the near future, he is faced with the replacement of manufacturers, that is, Canon may launch a brand-new machine to replace invincible rabbit within half a year, and invincible rabbit is facing production suspension. If you want to buy the next generation of Canon products, you can wait.

Although few people play the whole machine renovation in modern times, it is better to be careful when buying tens of thousands of dollars in specialty stores or large computer cities in big shopping malls. Even if there is a problem, it is convenient to defend rights. Online shop, there are good and bad, thousands of miles away, I don't understand!

As for the price, Canon controls it very well. But shopping around without losing money is the last word. As time goes on, prices will vary from place to place. It is suggested to check the well-known digital websites such as bubble net and Pacific Network, which generally have local prices. In fact, I ran a few more stores, and the difference was not bad.

4. the money to buy a SLR camera should be prepared: a. lens. We need a lens to test the SLR camera. Through the test, we can know some basic performance of the second-hand camera (invincible rabbit, please bring a full-size lens). B, memory card and card reader need to take some test photos when buying a camera, so these two are indispensable. C, if possible, bring a notebook computer with DeadPixelText software installed, and test the bad points of photosensitive elements, focusing accuracy and shutter times (if you are lazy, you can use a light and shadow magician), or you can use a merchant's computer. D, the most important thing is money!

5. To get a SLR, we must first look at the overall appearance and color of the camera. See if the camera body is fresh enough, whether the paint has fallen off, whether there is any bump and scratch, and whether the skin has fallen off. If you feel old-fashioned at first sight, then I advise you to change your home.

6. Next, carefully check every screw hole of the camera for signs of screwing. If there are obvious traces of screwing, and there are many kinks, it basically means that the machine has been dismantled and repaired, or even maliciously refurbished. If you encounter the above situation, personally, you don't think it is necessary to continue buying. After all, what is inside the fuselage of a disassembly machine is estimated to be clear only to merchants.

7. Then, you need to check the looseness and usage of each button on the machine. If the buttons are obviously loose or the words printed on them are blurred, it means that this camera has been running with its former owner for a long time, and even used the broken buttons to reinstall a new one. Everyone must pay attention to this when buying, because this is really an easy-to-forget inspection item.

8. Battery compartment, hot boots and all interfaces are places that need to be checked. Let's see if there are any traces of oxidation and overuse above. For a simple example, if the battery compartment is seriously corroded, the battery will consume electricity quite quickly when we use it, which will directly cause short circuit damage to the machine.

9. It is particularly important to check the aging degree of the built-in flash. You know, every time you use it, the flash will age. It is not easy to accurately check whether the flashing lights are aging. You can look at the effective distance of the flash indicated in the manual, then take pictures within this range to see if the brightness is enough and there is no color cast, and then infer the state of the flash.

10, the next and most important point is to check the bad points of the photosensitive element and LCD screen. The specific method is: set ISO to the lowest, cover the lens, and take an all-black photo with the highest resolution and quality (if possible, you can take another photo with the same parameters of red, green, blue and white). Then first look through the camera LCD screen to see if there are any bad points that are not displayed. Then import the picture into the computer, and check whether there is any bad spot on the photosensitive element with Dea PixeTest software. If there are no problems in the above inspections, then basically this SLR has passed the test.
