Systems and methods for lens characterization
Methods and systems for analyzing camera lenses and presenting information regarding camera lenses performance are described. An interactive user interface is provided over a network for display on a user terminal by a computer system. A user request is received at the computer system from the user terminal for lens data from a first lens. Lens data, including test data obtained via a first digital image captured using the first lens at the first focal length setting and the first aperture setting is accessed from memory and transmitted to interactive user interface. The interactive user interface is configured to display an identification of the first camera body, an identification of the first lens, the first focal length setting used to capture the image, and the first aperture setting used to capture the image. Using the lens test data, the interactive user interface generates and displays sharpness graph data.
