:: Auto Focus Mode ::

There are normally has three options, one for focusing on the static subject,one for focusing on a moving subject and a third, which is a mix of both.

AF-S (Single -servo AF): General mode to use, it's will be autofocus locks on the subject, no matter if subject or we change our distance the focusing still remind at the first lock focusing.

AF-C (Continuous - servo AF): Work together with Dynamic Area AF setting & Choose option Continues shooting. Useful for moving subjects. The autofocus system will constantly analyse the subject distance & make adjustments. However tracking fast moving, action subject such as motorsports, Single AF point will improve accuracy.

AF-A (Auto-servo AF area): Mixing both mode option an above. It's will lock to stand still subject & detect to minor moving subject. However if it detects a major change in distance it does not refocus.

M (Manual lens focusing): Best use when low light, low contrast subject or shooting through glass where we may find AF struggles. Shooting close-ups when working with very short focusing distances.

Aoto Exposure Lock (AE-L) / (AF-L) Auto Focus Lock: This option on the top of the LCD monitor designed to lock the current exposure setting so that it does not change when we recompose image, even incoming light level change. Press halfway Shutter Button + (AE-L) / (AF-L) . Ideal for very dark/light subject or positioned in a bright/dim area.

:: Active D-Lighting ::

Designed to help ensure for retain highlight details when shooting in a high contrast situation, such as direct bright sunlight. The under exposure helps keep the highlight from becoming blown out & losing details. At the same time, it's also make auto adjustment to avoid losing details in the shadow area

.

:: Auto ISO mode ::

Particularly useful when light level are changing or working in a fast pace and we do not always have a chance to notice whether the shutter speed has dipped into the camera-shake territory. This auto ISO setting will raised automatically as light level dim, in order to maintain a shutter speed for shake-free handheld shooting.
