The EX-250 is exactly the same as the cheaper EX210, other than the inclusion of 16GB of internal flash memory. Key features include a 1.5 megapixel backlit CMOS sensor, 40x optical zoom, 3-inch touchscreen LCD, and built-in WiFi. Video quality is good if not great, due partly to the small size of that CMOS sensor when compared to higher-end models. The EX-250 is a bit of a hard sell in some respects, as that included memory boosted the cost a full $100.
