Featuring 12-megapixel resolution, the Optio A40 features three types of Shake Reduction, including mechanical, digital and movie. Each version helps deliver sharp, blur-free shots where camera shake is an issue such as action photography or in low light conditions at dawn, dusk or at night. The Optio A model also features the newest Face Recognition technology including a Natural Skin Tone mode and a Half-length Portrait mode, which automatically takes a head and shoulder photograph of subjects.
