Glossary of terms
Spot metering
The meter reading is taken from a very small area around the center of the subject, defined by
the spot metering area mark in the viewfinder. Spot metering is ideal for use in difficult light
conditions, or when the important element of the picture (subject’s face) is small. Use spot
metering for backlit subjects, or sports and stage performers. See also digital ESP metering and
center weighted averaging metering.
Synchro Terminals
Terminals on an external flash unit for connecting it to the camera.
TIFF (Tagged Image File Format)
A format used for saving highly detailed black and white or color image data. TIFF image files can
be handled by software programs for scanners and graphics applications. Non-compressed
image data are stored in this format with this camera.
TFT (Thin-Film Transistor) Color Monitor
A color monitor constructed using thin-film technology.
TTL phase-contrast detection system
This is used to measure the distance to the subject. The camera determines if the image is
focused by the detected phase contrast.
TTL (Through-The-Taking-Lens) System
To help adjust exposure, a light receptor built into the camera directly measures the light passing
through the lens.
TTL-AUTO
For use with an external flash. Light emitted by the flash is measured by the light receptor in the
camera as it passes through the lens. A signal is then sent to adjust the external flash intensity.
