Olympus has released a new website aimed at explaining the varying focal lengths of the Four Thirds lens system.

The Lensfinder features a photo with a slider beneath that can be altered between a wide angle of 14mm and tele end of 600mm, in 35mm equivalent terms.

The photo itself then alters to give a visual representation of the image that focal length produces, while a table underneath the image displays all Olympus lenses covering that focal length.

Visit the Lensfinder yourself to find out more.
