5.3 Ovládání clony

The F1.2 large aperture allows for significant control over depth of field. Use wider apertures (smaller f-numbers like F1.2, F1.4) for shallow depth of field and pronounced background blur (bokeh). Use narrower apertures (larger f-numbers like F8, F11) for greater depth of field, keeping more of the scene in focus.
