Sharp, Clear 20x Lens: The FinePix F800EXR camera uses the FUJINON 20x Super Wide-Angle optical zoom lens that produces crisp high resolution results throughout the focal range, from 25mm wide-angle to 500mm telephoto, along with a Super Macro Mode that allow sharp focusing down to 5cm delivering the most brilliant detail possible.
This means the rear lens elements are as close as possible to the sensor, reducing the back focus distance of each lens to the minimum possible, thus achieving high resolution from edge to edge.
