Zusammenfassung:	An optical assembly for a point action camera or other compact digital camera having a wide field of view, includes multiple lens elements, including at least one lens element that has an aspheric lens surface. The optical assembly is configured to provide a field of view in excess of 120 degrees. The optical assembly has a modulation transfer function (hereinafter "MTF") at the Nyquist frequency that is above 0.3 and a MTF at half Nyquist frequency that is above 0.5 across the wide field of view.
