What makes it special, not just within the Micro Four Third catalogue, but in any system, is the f1.8 focal ratio, the World's brightest for a Fisheye. This lets you keep shutter speeds higher or sensitivities lower than other Fisheyes under the same lighting conditions, which is a boon whether you're shooting stills or video. Couple it with the fantastic stabilization built-into Olympus bodies, particularly the OMD EM5 Mark II, and you'll rarely find the need to shoot above the lowest sensitivities, ensuring great quality results.
If you are an action, concert, astro or underwater photographer who often encounters low-light situations, the extreme wide angle combined with the very fast aperture and close focussing capabilities could definitely be a great advantage.

Images shot with the lens offer pleasing sharpness; corners are often out of focus in wide-aperture (ƒ/1.8) shots because of the subject distance, rather than characteristics of the lens. It doesn't take much to get the full frame of a scene in focus - just back up and stop down a few aperture stops.
However, users of the Olympus OM-D series M4/3 cameras who need with wide angle coverage will find it an excellent performer, particularly if they also require weatherproof sealing.
Underwater photographers will find the new fisheye lens can offer dramatically different viewpoints from the usual wide-angle lenses and its fast maximum aperture will be a genuine advantage. For these users, Olympus offers an optional PPO-EP02 underwater lens port that has been designed specifically for this lens.
