Masters can share the continuous shooting skills of SLR cameras, such as how many shutters are safe, and whether the focus is center focus or full-screen autofocus.

Safety shutter = 1/ focal length

That is, the focal length is 50MM, the safety shutter 1/50 seconds, the focal length is 200, and the safety shutter 1/200.

Now all lenses have anti-shake function, which can improve the shutter speed by 3-4 levels. For example, increasing the shutter speed of the third gear is 65,438+0/65,438+00 seconds, which means that you can take a photo with a focal length of 20 seconds without pasting. Generally, the safety shutter is determined according to the focal length. Anti-shake lens can reduce the shutter speed of 3rd gear.

Whether the focus is centered or automatic depends on the actual situation. When shooting people, the focus is on the eyes, ensuring that the focus of the eyes is correct, automatic or fixed, and ensuring that the eyes are focused.

Scenery, humanities, and autofocus are all acceptable. Wide angle generally requires a large aperture, above F 10, which is also not fixed. Sometimes it is common to need F22. It depends.
