Hobbyists, photo enthusiasts and professionals alike will be captivated by the M.ZUIKO DIGITAL ED 8mm f/1.8 PRO Fisheye lens' 180-degree diagonal angle of view. Like the M.ZUIKO DIGITAL ED 7-14mm f/2.8 PRO, this lens includes dustproof and splashproof construction, for unlimited wide-angle adventure. The lens is also compatible with a custom dome port for use with an Olympus underwater housing.

The M.ZUIKO DIGITAL ED 8mm f/1.8 PRO Fisheye lens is constructed of 17 elements in 15 groups and can capture high resolution at the very edges of an image, even at the maximum aperture of f/1.8. ZERO Coating minimizes optical flares and ghosting. The lens also comes with a fixed lens hood and a pinch-style lens cap LC-62.

From under the sea to the night sky, the record-breaking new M.ZUIKO DIGITAL ED 8mm Fisheye 1:1.8 PRO is an unprecedented opportunity to add stand-out creativity and a uniquely dynamic and abstract look to extremely wide-angle shots of the natural world. Unprecedented, because – in this category – the Fisheye PRO is the world’s brightest fisheye lens*. The super-large aperture ensures photographers top-notch optical performance in any conditions, especially in low light. The 2.5-cm minimum focusing distance (measured from end of the lens) and maximum magnification of x0.2 make it a logical choice for nature photographers with a passion for quirky perspectives and eye-catching bokeh.

But the Fisheye PRO is also ideal for fast-action sports photography; landscape, nightscape and sky panoramas; as well as crowds, interiors or architecture. For underwater specialists, it likewise opens up exciting new opportunities – it’s compatible with a range of accessories via the new underwater lens port PPO-EP02.

Like the other lenses in the M.ZUIKO PRO family, it’s extremely compact and lightweight, especially compared to equivalent D-SLR rivals. The build quality is top notch. In pre-launch tests, professional photographers were quick to praise the blur-free performance of the Fisheye PRO at both ends of the f stop scale. Light fall-off at the edges is negligible, as are both chromatic and comatic aberrations, particularly when compared to equivalent rival lenses.
