Canon 5d2 lens 24- 105 is used to shoot large landscapes, with aperture priority. What's the difference between f8, f 1 1 and f 16? What should I choose?

There is a difference between sunny and cloudy days. Generally speaking, there is no difference when F8, F 1 1 and F 16 are used in sunny days with good light conditions (except for the sharp change in image quality that is invisible to the naked eye, the change under these three apertures is not great, and the change is more obvious when the focal length is 105mm, compared with the wide-angle end of 24mm).

When it is cloudy, the influence of shutter on jitter should be considered when the aperture adopts these three gears. Because of underexposure, the camera is prone to shake after lowering the shutter, which is a big trouble for landscape photos that require sharpness and transparency, so if you must shoot on cloudy days, you can consider enlarging the aperture appropriately; If you don't want to reduce the sharpness by increasing the aperture, there is only one way-tripod, and all serious photography creation can't be separated from tripod.

(Improving sensitivity is not recommended. Although invincible rabbit's noise control ability is first-class, it is not recommended to consider it later ~)
