As with its camcorder lineup, announced at CES earlier this month, Sony’s eight new digicams offer a stable of new features appealing to almost every price point.

The line includes eight cameras, including two-entry level models and an ultra zoom. The higher-end models boast new features like Smile Shutter Mode and intelligent scene recognition, while the budgets now have face detection and rechargeable batteries.

The DSC-T300 ($399, March), the most high-end of the cameras released today, has 10.1 megapixels, 5x optical zoom, a large 3.5-inch LCD, and plenty of new features, including an improved face recognition, which distinguishes between adults and children, and Smart Shutter Mode, which takes a picture as soon as it detects a smile, without the user having to press the shutter and users can set this mode so that it only reacts when children or adults smile. Sony’s new intelligent scene recognition (iSCN) allows the camera to automatically select the optimal scene mode, given the lighting and environmental settings it detects. The T300 also includes Sony’s D-Range Optimizer (DRO), which enhances detail in photos taken with a harsh backlight.

Sony’s four new W-Series cameras include the 7.2-MP DSC-W120 ($199, March), 8.1-MP DSC-W130 ($229, March), 8.1-MP DSC-W150 ($249, April), and the 10.1-MP DSC-W170 ($299, April). All of these models include Smile Shutter Mode, semi-manual focus, an improved autofocus system, and Sony’s DRO. The W150 and the W170 also include iSCN as well as new playback options, which allow users to search by date and smile.

The DSC-H10 ($299, May) has eight megapixels, a 10x Zeiss optical zoom lens, a three-inch LCD, and ISO up to 3200. Like the W-Series cameras, it includes Sony’s DRO. Other features include HD output, face detection, Sony’s DRO, Advanced Sports Shooting mode, and musical slide show options.

The two new entry-level models include the DSC-S750 ($149, March) and the DSC-S780 ($179, April). With these models, Sony is upgrading its budget line from AA to rechargeable Lithium Ion batteries, and is introducing face detection, a feature once found only on higher-end digicams. The 7.2-MP S750 and the8.1-MP S780 each have 3x optical zoom, 2.5-inch LCD screens, 22MB internal memory, and a slot for an MS Duo or MS Pro Duo card (up to 16GB).
