Minimum Focusing Distance
The invisible boundary that decides how close your lens can get before everything blurs
3 hours ago
0
How does the minimum focusing distance of a lens influence the type of photography you can do?
It limits how close you can get to a subject while keeping it in sharp focus, affecting close-up and macro photography.
It determines the maximum zoom level of the lens for distant subjects.
It only affects the camera’s ability to focus in low light conditions.

F-stop (F-number)
How the f-stop controls light and depth of field in photography lenses
1 Feb 2026
0
How does changing the f-stop affect the depth of field in a photograph?
Lower f-stop values increase the depth of field, making more of the image sharp.
Changing the f-stop has no effect on depth of field, only on exposure.
Lower f-stop values produce a shallower depth of field, while higher values increase it.
