Other features include a MPEG-4 DivX® Movie Mode, and 23MB of internal memory. In addition, the Optio S7 is the first compact PENTAX digital camera to accept the new SDHC (Secure Digital High Capacity) memory cards in addition to SD memory cards. SDHC (also know as SD 2.0) is a FAT32-compliant format designed for capacities up to 4GB or more.
Also featured in this newest Optio digital is Face Recognition AF & AE, a function that simplifies portrait-taking by automatically detecting the position of the subject's face and adjusting the focus and exposure based on the detected position.
The Optio S7 is equipped with a Blur Reduction mode, a new feature that allows photography at faster shutter speeds for sharper images even in dim lighting conditions such as night scenes and indoor sporting events. In this mode, the camera automatically adjusts the sensitivity to as high as ISO 1600 to match the brightness of the subject. The higher sensitivities permit faster shutter speeds that effectively reduce not just camera shake but also blurring caused by moving subjects.
The Optio S7 auto-tracking AF feature continuously focuses on subjects such as kids and pets that move around unpredictably. Since the focus frame automatically follows the movement of the subject inside the photo frame, you can be sure to capture those instantaneous photo opportunities.
The Optio S7 captures movies at 30 fps (frames per second) at sizes up to 640 x 480 pixels with image quality rivaling camcorders. Since it employs the DivX® (MPEG-4 compliant) movie format, the Optio S7 can record longer, high-quality movies. Camera shake while filming can also be corrected automatically by switching on the movie anti-shake feature.
