The PhotographyBlog has a review on the Pentax Optio S7 where they write, 'The Optio S7 is the latest model in the PENTAX Optio S series, which is known for slim, stylish, full-featured digital camera bodies. In addition to an upgrade to 7.0 effective megapixels, this model features an easy-to-use Blur Reduction High ISO mode to help reduce the effects of camera shake and subject blurring for sharper images even in dim lighting conditions such as night scenes and indoor sporting events. In this mode, the camera adjusts shutter speeds automatically to an ISO as high as 1600 to match the brightness of the subject.'
