The Olympus Lensfinder is a new feature on the Olympus website that aims to help you find the right lens for your Olympus Four Thirds DSLR camera.
Lensfinder works by showing you the same scene photographed from the same viewpoint, but at different focal lengths. Move the slider to a focal length you want, and the image displayed zooms in or out depending on how you want the image to appear. At a particular focal length, the Lensfinder displays all Olympus-branded Four Thirds lenses capable of shooting at that focal length.
From there, you can click on any lens you’re interested in and it brings you to a page that gives a full description of that particular Olympus lens.
