Release-Priority for autofocus

Shutter can be released anytime (i.e,, even when subject is not
in focus). Convenient so you do not miss an opportunity to take

a picture and are not concerned with absolute focusing

precision.

With N90 camera body, Release-Priority is given to Continuous
Servo AF while Focus-Priority is given to Single Servo AF.

Flowever, the Electronic Organizer can change the priority to

perform Focus-Priority Continuous Servo AF or Release-Priority
Single Servo AF.

Single Servo AF

Once the subject is in focus, focus is locked. Useful for

recomposing the picture.

SLR

Single Lens Reflex. A type of camera in which you look through
the camera's lens as you view through the cameras viewfinder.
Other camera functions, such as light metering and flash
control, also operate through the camera’s lens.

TTL

Through-the-Lens. Most SLR cameras have built-in meters

which measure light after it has passed through the lens, a

feature that enables exposure readings to be taken from the

actual image about to be recorded on film, whatever the lens
angle of view and regardless of whether a filter is used or not.
