Selection skills of professional SLR cameras

Nowadays, photography is no longer an amateur activity that only a few people can enjoy. SLR cameras are penetrating into everyone's life at an extremely fast speed. So how do you choose a professional SLR camera? Don't worry, let's take a look at the purchasing skills of professional SLR cameras.

Selection skills of professional SLR cameras

1, buy a SLR camera to determine the acceptable price, which is more purposeful.

Low-end entry-level digital SLR package (D60,4400D, K 100D, etc. ) less than 5000 yuan.

5000-8000 yuan low-end entry-level or advanced digital SLR body (450D, D80, etc. )+Another popular shot.

8000- 10000 yuan low-end digital SLR body+another large aperture zoom lens.

10000- 15000 yuan mid-range digital SLR body+with large aperture zoom lens.

15000 yuan or more, this range is very wide, so I won't discuss it in detail.

Step 2 look at the brand

In fact, many novices have no so-called brand preference, and they actually don't know which brand is better. However, some buyers have used some brands of digital cameras themselves, and feel that the brands they are used to will be better. Although this idea can narrow your choice a lot, it may also miss the excellent models of other brands. When choosing, you should abandon brand preference, accept other brands and choose the car that suits you best.

3. Watch metering and exposure

In this regard, although there are some "selling points" differences in technical details, it can be considered that there is no difference in essence and there is no need to delve into it.

4. Look at the focusing speed, shutter lag and continuous shooting speed.

These indicators are very important for news photography, sports photography, wildlife photography and snapshot photography. For digital SLR cameras, the improvement of performance is accompanied by a sharp increase in price.

5, look at the shutter life

The shutter life of general SLR cameras is 50,000 times, the life of high-end SLR cameras can reach 8-65438+ 10,000 times, and the longest life of professional SLR cameras can reach more than10.5 million times. In practical use, if the high-speed continuous shooting function is often used, the shutter life will be reduced.

6. Look at the reliability of the fuselage

Advanced cameras are dustproof and waterproof, and can resist impact. Because of the metal body and special materials, the price of such a camera will be high.

7. Look at the color space

In addition to sRGB as the standard color space for Windows and inkjet printers, you can also choose to use more widely AdobeRGB. You can choose the best color space according to the purpose of photography.

8. Look at the flash system

For professional photographers, flash metering and exposure system is very important. Each manufacturer has its own unique skills in the automation of flash system, and there is no best or worst, only the most suitable.

9. Look at the camera

The advantage of a digital SLR camera is that the lens can be changed. Whether the original lens series support and the products of independent lens manufacturers are rich enough to meet your needs is a problem worthy of attention.

10 to see if it supports W/A read-write acceleration technology.

All digital SLR cameras released after the fall of 2003 will support W/A reading and writing acceleration technology. With this technology, the reading and writing speed of TF card can reach more than 40 times (25MB/S).

1 1, see the transmission interface.

Digital SLR cameras released after the fall of 2003 should have both USB2.0 and 1394 firewire terminals. Some cameras should also support wireless network transmission such as 802. 1 1b/g and Bluetooth.

12, look at the shutter

The highest shutter speed and the slowest shutter speed (B door) are two key indexes of digital SLR camera shutter. The reliability and accuracy of the shutter also need attention. The highest flash synchronization speed is also a sign to measure whether a digital SLR camera is advanced or not.

13, handle, shape, weight

Whether the fuselage design is suitable or not is often the most important place to decide to buy a SLR camera. Regardless of the price, the size and weight of professional digital SLR cameras are not acceptable to everyone. Small and lightweight amateur digital SLR cameras are more suitable for ordinary people.

14, is it simple and convenient to see the dust?

It is also a headache for digital SLR users. Because the digital SLR can change the lens, it also causes dust to easily enter the interior of the fuselage, which will have a certain impact on imaging when it falls on the photosensitive element. Be sure to pay attention.
