2. 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.
3. fuselage life. If the high-speed continuous shooting function is often used, the shutter life will be reduced. The service life of LCD screen is about 1000 hours. Reflective framing system is a component that affects the life of digital SLR cameras. Frequent and high-load use can easily lead to the failure of reflective frame system.
4. 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.
5. Color space. In addition to sRGB as the standard color space for Windows and inkjet printers, you can also choose to use more widely Adobe RGB. You can choose the best color space according to the purpose of photography.
