Here we have a couple CCTV lenses using the C-Mount 'standard': Computar 12.5mm F1.3 and Canon 12.5-75mm F1.8. Even though both are made for 1" or 2/3" (respectively) format video camera, they can be used on Micro 4/3 camera, such as an Olympus E-PL1, via an adapter. Aside from being bright and fairly wide, both lenses vignette quite a bit.

Cameras such as the GF1 and E-PL1 from Panasonic and Olympus, respectively, are using the new Micro 4/3 format standard, which is a type of Electronic Viewfinder, Interchangeable Lens (EVIL) camera. Despite the dubious acronym, the "EVIL" concept is intriguing as it provides DSLR image quality in a smaller, prosumer point-n-shoot like body accomplished by removing the mirror box and optical viewfinder. A side effect of this is a reduction in the flange focal distance (aka flange-to-film distance or back-of-the-lens-to-film/sensor distance in layman's term), which allows the "EVIL" camera to accept and (manually) focus almost any mass-produced lens via adapters. This means, you can use your daddy's film camera lenses on your brand spanking new Olympus E-PL1 or the soon-to-be available Sony NEX3/5.
