Input:
User Review: I bought this camera based on size and 3x zoom. The image quality was better than I expected.
You will need several accesories. I bought four extra batteries, two 128 & one 256Meg compact flash cards, a padded neck strap, and a little CaseLogic nylon case to hold everything.
Pros:
Small Size
Great Image quality
Camera software speed
USB cabled remote control
JPEG compression very clean, artifacts hard to find even at highest compression setting.
Cons / Missing Features:
Camera does not draw power from USB cable.
Battery life is short.
Autofocus delay makes candid shots impossible.
Small lens aperature makes action shots difficult in all but brightest of light
No IR remote
Movie length limited to internal memory not flash card size.
Camera does not hold "motor drive" setting through power cycling.
Creation dates of files all set to 1979.
Supplied Image Browser software sets file modification date to date file downloaded, not date picture taken. There is no provision to have camera name files with embedded date format like 2002_02_12_14_56 00002.
Many button pushes go unrecognized. You must watch screen carefully to make sure correct mode is selected. Simply counting button pushes may get you self timer instead of "motor drive".
Supplied 8meg card is useless because of small capacity.
The batteries are very expensive and the supplied charger only charges one at a time.
Automatic white balance setting does poor job, can't even recognize daylight. You must manually select correct setting, or risk nasty blue cast to outdoor photos.
Tripod socket not centered on lens opening.
No provision to turn off digital zoom.
No optical viewfinder indication of digital zoom range access.
Zoom non functional during movie capture.

Macintosh users shouldn't suffer with the included image browser software.  Try Cameraid and GraphicConverter instead.
