The film 100% magnification shot by Canon 7D is all false, especially in the aperture range of F4-F8.0, which is almost blurred and the background is unclear. It was fast when it was filmed.

1. The shutter speed will always shake when shooting with a hand. 24- 105 camera has anti-shake function, which can improve the safety shutter coefficient and ensure the clear picture when shooting by hand. Try to hold your breath when you press the shutter. You can maximize control, reverse test, set the camera to delay shooting, put it on the table or set up a tripod, and stop the lens anti-shake function to shoot. If there is no blurring effect in the picture, it proves that you have a shaking scene when shooting. Please practice stabilizing the camera and pay attention to the posture of holding the camera!

2. The larger the aperture of the aperture, the shallower the depth of field and the larger the shooting space, which will produce different effects of the whole picture, but the focus is definitely clear, that is, the focal plane is absolutely clear, which can be calculated by the depth of field formula.

3. Focus mode Professional SLR cameras include automatic servo focus mode, single focus mode and continuous focus mode. If you move the camera, focus cheaply or use the autofocus point, it will cause unclear focus, because the focus on the face is more accurate or strictly speaking, it can be set to single focus, and you can shoot with the shutter AF locked. Detection method: focus on the wall (vertical plane) with obvious patterns for detection.

If the above methods are not enough to solve the problem, please give up the camera or photography, hehe, just kidding!
