What is the reason why the photographic image of D51 camera is weak?

weakness, many people also call it paste. I can only analyze several possible reasons.

1. wrong focus selection, such as not setting the focus state to auto focus and not performing accurate manual focus;

2. The focus mode is wrong. The focus modes of Nikon camera are: AF-A, AF-S and AF-C. When shooting static objects, try to set the mode to AF-S, that is, single focus, and the camera will ensure that the shutter can be released only when the focus is accurate.

3. When the light is insufficient, the shutter speed is too slow, and the blur is caused by jitter. Increasing the sensitivity or turning on the flash can solve this problem;

4. The subject moves at a high speed, while the shutter speed of the camera is slow;

5. When the camera is placed on a tripod to shoot a still life, use a slow shutter, and the lens anti-shake VR system is not turned off;

6. The camera is broken;

7. The lens is broken;

8. I spent my eyes
