Fokusavimo režimo jungiklis (AF/MF)

Located on the side of the lens barrel (refer to Figure 3), this switch allows you to select between Autofocus (AF) and Manual Focus (MF) modes.

• AF (automatinis fokusavimas): The camera automatically focuses on the subject. This mode is suitable for most general photography.
• MF (rankinis fokusavimas): You manually adjust the focus by rotating the focus ring. This mode is useful for precise focusing in specific situations, such as macro photography or astrophotography.

Rankinio fokusavimo žiedas

When in MF mode, rotate the large ring towards the front of the lens to adjust the focus. The focus distance scale, visible through a window on the lens barrel, indicates the current focus distance in both feet and meters.

Aperture (f/1.4)

This lens features a wide maximum aperture of f/1.4. This allows for:

• Puikus veikimas esant prastam apšvietimui: More light can enter the lens, enabling photography in dimly lit environments without excessively high ISO settings.
• Mažas lauko gylis: Creates a blurred background (bokeh) to isolate your subject, which is ideal for portraits and artistic photography.

Mažiausias fokusavimo atstumas

The lens has a minimum focus distance of 7.1 inches (approximately 18 cm), allowing for close-up shots with a wide perspective.
