How can SLR photos be taken more clearly?

If you shoot by hand, try to ensure that you shoot in bright light. If shooting in dark light, it is best to find a tripod or hard support, or use a large aperture to ensure the shutter speed. Generally, the safe shutter speed = the reciprocal of the focal length, that is, if you shoot with a 50mm lens, 1/50 seconds is the minimum shutter speed requirement. If the camera pixels are too high, you need to increase the shutter speed.

In addition, it is easier to shake and blur when shooting with telephoto, because telephoto requires higher shutter speed, so try to choose telephoto with anti-shake function, such as Canon's 70-200 F2.8 second-generation anti-shake lens (commonly known as White Rabbit).

Be careful not to shake the camera when shooting, and gently press the shutter to be steady.

If shooting on a tripod or with a stand, try to choose wired release or selfie, and count down to 10 second.

All of the above can make the shooting clear. If these reasons are ruled out, the final reason does not rule out that the camera is out of focus, and it needs to be fine-tuned in the camera or adjusted in the maintenance center.

Typing word for word, I hope I can help you, and I wish you a happy photography!
