Major Features
1. Water and dust protection for worry-free use in all kinds of environments
The Optio W20 features a waterproof design that meets the JIS Class 8 waterproof standard, enabling it to withstand up to 30 minutes of continuous operation at an underwater depth of 1.5 meters, without needing a waterproof case. Furthermore, it meets the JIS Class 5 dustproof standard. Thus, this camera is ideal for use when skiing, taking part in marine sports, going fishing, or enjoying other outdoor events as well as gardening, cooking, or in other places where you would normally worry about water or dirt.
2. New Blur Reduction mode reduces camera shake and subject blurring
The Optio W20 is equipped with a Blur Reduction mode, a new feature that lets you take photos 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 sensitivity permits faster shutter speeds that effectively reduce not just camera shake but also blurring caused by moving subjects. Pentax Optio W20: Digital Photography Review
