(Wednesday, September 3, 2003 - 11:01 EDT)

Pentax Corp. has today announced three new digital cameras which it will be previewing at the Digital Focus media event on September 15th alongside the PC EXPO trade show in New York.

The first of the announcements - the Pentax Optio 555 - is an evolutionary update to the existing Optio 550 model, which we felt worthy of inclusion on our Dave's Picks list when we reviewed it earlier this year. Whilst the general layout of the camera remains much the same, it has been totally restyled. Gone is the dramatic silver trim around the lens, in favor of a much more conservative design with subtle detailing that will also make the camera easier to grip.

The 5 megapixel image sensor and 5x optical zoom lens are the same as used on the previous camera. Manual focus mode now allows focusing right down to the 0.79 inches that both cameras offer automatically in Super Macro mode, rather than being limited to the standard Macro mode distance of 5.9 inches. Pentax now lists the main AF mode as a "wide AF" rather than a 5-point AF. Shutter speeds now range from 15 to 1/2000 second, rather than the previous 4 to 1/4000 second - which should make the camera more useful for night photos, but may slightly limit options for freezing high-speed action.

Unlike its predecessor, the Optio 555 is what's generally referred to as a "shooting priority" camera - meaning that when in playback mode, simply touching the shutter button will revert the camera to capture mode, avoiding missed photo opportunities. Pentax says that shutter lag on the camera has been reduced, which should also help in this area.

The Optio 555 now offers flash exposure compensation, which should make it easier for users to get good flash exposures. The movie mode is no longer limited to 10 minutes - movies can now be as long as you've got capacity to store on your Secure Digital or MultiMediaCard. The camera no longer has 16MB of built-in memory; the press release doesn't state if a memory card is bundled. Images can now be rotated in-camera, and the Optio 555 gains PictBridge compatibility for printing images without a computer (on PictBridge-compatible printers, of course).

The Pentax Optio 555 will ship in October, with pricing not yet announced. Specifications, product photos and the Pentax press release follow below:
