5.1 Àfiyèsí Ọwọ́
This is a manual focus lens. To achieve sharp focus, rotate the focus ring on the lens barrel until your subject appears clear in the viewfinder or on the LCD screen. Many modern mirrorless cameras offer focus peaking and magnification assist features to aid in precise manual focusing.

5.2 Iṣakoso Afara
The lens features a manual aperture ring. Rotate the aperture ring to select your desired f-stop (from F2.8 to F16). A wider aperture (smaller f-number) allows more light and creates a shallower depth of field, ideal for subject isolation. A narrower aperture (larger f-number) allows less light and creates a deeper depth of field, suitable for landscapes or group shots.

5.3 Macro Photography
The 1:1 magnification ratio makes this lens excellent for macro photography. When shooting macro, precise focusing is crucial. Consider using a tripod to minimize camera shake and ensure sharp images. Experiment with different apertures to control the depth of field, as macro photography often results in very shallow depth of field.
