Advantages of SLR lens:

1, advantages of image sensor

For digital cameras, the photosensitive element is one of the most important core components, and its size is directly related to the shooting effect. The most effective way to get good shooting results is not only to increase the number of pixels, but also to increase the size of CCD or CMOS.

2. Rich lens selection

As a comprehensive product of optics, mechanics and electricity, the performance of optical imaging system is also very important to the final imaging effect. Having an excellent lens is no less than choosing an image sensor.

3. Fast response speed

One of the biggest problems of ordinary digital cameras is the lag of shutter time. If you don't grasp it well, you will often miss the best moment. Response speed is the advantage of digital SLR camera. Because the focusing system is independent of the imaging equipment, it can basically achieve the same response speed as the traditional SLR camera, which brings great convenience to users in news and sports photography.

4. Excellent manual control ability
