Today at the PhotoPlus Expo Trade show in New York City, Sony announced two new additions to its S-Frame digital photo-frame lineup: the DPF-D100 and DPF-D80. Both frames have SVGA (800 by 600) LCD screens and are Sony's first digital photo frames with a 4:3 aspect ratio.

The 10-inch DPF-D100 ($280 direct) and the 8-inch DPF-D80 ($180 direct) feature advanced imaging processing that allows them to display images of up to 48-megapixels or files as large as 100MB. The frames themselves have only 200MB of onboard memory but can support a wide variety of Flash memory types, including Memory Stick PRO, Memory Stick PRO Duo, SD Memory Card, MMC, Compact Flash, Microdrive, and xD-Picture Card.

Photos can be transferred to the frame via a non-included USB cable. As for file-format support, the frames can display JPEG and RAW (SRF, SR2, ARW) image files.

Sony has also several cool features in the frames, including 10 slide-show variations, clock and calendar views, and two index modes, which let you view all your shots at once. The frames also have an auto-orientation feature that can tell whether your photo is horizontal or vertical, and position it accordingly. The DPF-D80 is available now, and the DPF-100 will be available in November.
