Olympus 9mm F8 Fish-Eye Body Cap Lens

This is a prime lens for Micro Four Thirds, covering 9 mm (18 mm equivalent) and a maximum aperture of f/8. It weighs 30 g, and was released in 2014. That combination suits landscape and architecture photography.

It is an ultra-compact and lightweight accessory designed for Micro Four Thirds cameras. Combining the functionality of a body cap with a built-in fisheye lens, it offers a 140-degree angle of view, providing a unique perspective for creative wide-angle photography. The lens features a fixed F8 aperture and manual focus lever with settings for close-up (0.2 m) and infinity focus. Its slim profile makes it an ideal travel companion, allowing photographers to capture distinctive images without adding bulk to their camera setup.
