Here is what the site says about that.

From Panasonic Lumix G 8mm f/3.5 Fisheye: Panasonic Lumix G 8mm f/3.5 Fisheye: A prime lens by Panasonic for Micro Four Thirds cameras, 8mm f/3.5. Specs - Maker: Panasonic - Focal length: 8mm (prime) - Maximum aperture: f/3.5 - Made for: Micro Four Thirds sensors - Mounts: Micro Four Thirds - Stabilised: no - Autofocus: yes What it frames like - On Micro Four Thirds (Micro Four Thirds): like 16mm on full frame; f/3.5 gives about the depth of field of f/7 there. ...

From Focal length converter: How it works: Multiply the focal length by the sensor's crop factor to get its full-frame equivalent. To go between two smaller formats, multiply by the first crop factor and divide by the second. Crop factors are measured on the sensor diagonal, so formats with a different shape (4:3 against 3:2) frame slightly differently across the width.
