You can zoom in up to 10 times with 'optical zoom', and up to 16.9 (DMC-TZ4: 15.9)
times with 'EX optical zoom' with lower picture quality. You can also use 'digital zoom' to_
zoom in even further.

@ YOUcan zoom further to the maximum digital zoom ratio if
'DIGITAL ZOOM' (P.34)is set to 'ON'.
@ Easy zoom cannot be used while recording motion pictures.
@The enlargement ratio displayed in the bar on screen is an estimate.
@ In certain recording modes, TELE MACRO function (R4O) is activated when maximum
zoom ratio is reached.
@A greater degree of distortion may be generated by taking wider-angled pictures of
close objects, while using more telescopic zoom may result in more coloring appearing
around the outlines of objects.
@The camera may make a rattling noise and vibrate when the zoom lever is operated
- this is not a fault.
@ Extended optical zoom cannot be used in the following cases:
B (MOTION PICTURE mode), 'HIGH SENS.', 'HI-SPEED BURST', and 'MULTI
ASPECT' (DMC-TZ5 only) scene modes
@When using extended optical zoom, zoom movement may stop momentarily near
maximum W (lx), but this is not a fault.
@'ZOOM RESUME' (R25) allows zoom ratio to be memorized even if power is turned off.
