Casio EX-Z57 Review
The EX-Z57 uses a 3-segment telescoping lens that makes it possible to provide 3x (35-105mm equivalent) optical zoom capabilities in an amazingly thin camera configuration. This is an all-glass Pentax SMC lens constructed of 6 elements in 5 groups with a maximum aperture of F2.6-4.8. It has a 4X digital zoom option.
The auto focus system covers 15.7 in. (40cm) to infinity in normal focus mode and from
2.4 in. (6cm) to 19.7 in. (50cm) in Macro mode. It also features an "Auto Macro" function, which
automatically switches between Normal and Macro focus modes. As you can see
from the animation above, the lens retracts fully inside of the camera when
powered down and is protected by a built in lens cover. On power up it only
takes about 1.5 seconds to extend the lens.
The built-in flash has modes for auto, fill, red-eye reduction and off. The
working range is approx. 1.3 ft. (0.4m) to 8.5 ft. (2.6m) at wide angle, and 1.3
ft. (0.4m) to 6.6 ft. (2.0m) at telephoto.
Located on the top are the power on/off and shutter release buttons.
The controls on the back are minimal but effective. All camera settings are changed
via an onscreen menu system on the huge and bright 2.7-inch color LCD. There is no
optical viewfinder, you frame and review on the color LCD.
At the top are the zoom control buttons, which also serve as the magnified
playback and index mode controls buttons when in Play mode. Below that are the
Play and Record buttons which select between play and record modes. The 4-way
controller lets you easily navigate menu screens or select images for
playback, you can program the "Left" and "Right" actions in the Setup menu to
change Rec mode, EV comp, ISO speed, Self-timer or White Balance, the center
SET button accepts menu selections. In Record mode you push "Up" to enable
Macro focus or to enable the Album mode when in Playback. You push "Down" in
record to change the flash mode or to delete an image when in Playback. And at
the bottom is the MENU button calls up and dismisses the onsreen menu system,
and the DISP button controls the amount of
information that is overlayed on the screen.
The EX-Z57 has 9.3 megabytes of internal memory for saving images and movie clips. It supports use of any size Secure Digital or MultiMedia Card via the expansion slot on the bottom. Image data can be copied to/from internal memory and a flash card via the Playback menu.
