With the Sony Cyber-shot DSC-W70, you can record good-looking VGA-resolution, 30fps MPEG-1 movies that play in Windows Media Player or QuickTime; they look better running at 320x240, however.
For the most part, the Cyber-shot DSC-W70 performs well relative to its classmates. From power on to first shot takes about 2.2 seconds, with about 1.4 seconds between shots thereafter. The flash recycles quickly, adding only 0.2 seconds to the shot-to-shot time. Though relatively fast to focus in good light -- shutter lag is a decent 0.5 seconds -- focus in dim light jumps to a not-so-good 1.9 seconds. Burst shooting at full resolution is limited to 4 frames at about 1.4fps despite its 58MB of built-in memory.
Although the Sony Cyber-shot DSC-W70 is a decent enough camera, both the DSC-W30 and the DSC-W50 are probably better value than the DSC-W70. Because they're lower resolution, the photos are a bit softer, but they also produce significantly less noise than the DSC-W70. If you need the higher resolution, check out one of Canon or Fujifilm's competing ultracompacts.
