The focal range of the W100’s lens (F2.8-5.2, 3X optical zoom Carl Zeiss lens) is 7.9 - 23.7 mm, which is equivalent to 38 - 114 mm.
This 8.1 Megapixel Camera is very effective at ISO 400 (reaches 1.000 lines/image length in the centre of the image and low noise). But ISO for this camera goes up to 1250. While it uses Memory Stick Duo cards, also has a 64Mb build-in memory. It uses the NP-BG1 lithium-ion rechargeable battery and, not very remarkably, you are able to get up to 360 shots before it runs out. Included with the camera is an external battery charger (4-5h for charge). Exposure time: 1/1000 to 30 seconds. Preparing for shot with the zoom lens will take 1.5 seconds and shooting 0.66 seconds. The built-in flash is a powerful one, with a working range of 0.2 - 6.0 m at wide-angle and 0.3 - 3.2 m at telephoto.
One bad thing about it is that there’s no custom white balance setting on the DSC-W100. Also, don’t expect a redeye reduction.
The important controls are easy to reach even with one hand but you better use two.
It’s design is the one Sony used us with: small flat pocket camera (ultra-compact), just a bit larger and heavier. This camera supports the USB 2.0 High Speed standard.
The MPEG Movie VX Fine mode takes VGA-sized video (that’s 640 x 480) at 30 frames/sec until the memory card is full, with sound.
Overall, i recommend this camera for the quality of clear image due to it’s ISO performances.
