apa gunanya yg tu?
aku tengah baca.pening jugak nak memahamkan.  http://photographylife.com/nikon-ae-l-af-l-button
- AE/AF lock – the default behavior of the AE-L/AF-L button. Will lock both camera exposure (shutter speed, aperture, ISO and white balance) and lens focus. The feature will only be active while you hold down the button. Once you release it, the lock will be released as well.
- AE lock only – will only lock the camera exposure, so focus will be reacquired if you recompose the shot. Also only works while you hold down the AE-L/AF-L button.
- AE lock (Reset on release) – exposure will be locked once you press the AE-L/AF-L button and will stay locked until you take a picture, even if you release it.
- AE lock (Hold) – exposure will be locked when the button is pressed and will stay locked even if you take multiple pictures. The lock will be automatically removed if the camera is inactive for a time period set in the “Auto meter-off delay” menu setting, or can be also removed by pressing the AE-L/AF-L button again.
- AF lock only – only focus will be locked while the button is depressed. The lock is removed as soon as you release the button.
When I use an entry-level DSLR, I either choose “AE/AF lock”, so that both exposure and focus stay locked together, or I set the button to “AF-ON” and use manual mode to keep my exposure consistent.
