Agreed but in some picture taking there are near subjects and far subects.Person 4or 5 feet away being potographed in front of his monument to himself.
The
Mavic 2 Pro has a 1” sensor and about a 9mm lens so we can calculate a lot from this.
Best depth of field for the
M2P is at f/5.6. Anything higher than that will actually suffer so badly from defraction that the lens will no longer be able to achieve “acceptable focus” (industry standard definition of 11 micron circle of confusion for 1” sensor).
See smaller sensors actually make the lens work harder because the lens must focus the light onto a smaller area. This is why defraction sets in earlier for smaller sensors. Ironically full frame and medium format lenses don’t have to be as perfect to achieve the same results. It’s ironic because those are almost always the best made and expensive lenses.
We can also calculate that the hyper focal distance of the
M2P is 5’ 11” at f/5.6 which would put everything from 2’ 11” to infinity in focus. The minimum focus distance of the
M2P is 2.1” so unless you have something of interest between 2’ 1” and 2’ 11” you don’t have to worry about depth of field.
In other words your as long as you focus the camera to about 6 feet everything will be in acceptable focus. Larger f-numbers are available to induce longer shutter times, to create sun stars (a direct result of defraction), or other creative uses. You wouldn’t want to use an f-number larger than f/5.6 to gain more depth of field because 1) it’s not needed and 2) everything will be soft.
