Weather-sealed Olympus diagonal fisheye with 180-degree view for Four Thirds system.
The Olympus Zuiko Digital 8mm f/3.5 Fisheye is a diagonal fisheye lens for the Four Thirds system, providing a 180-degree field of view corner to corner. Unlike circular fisheyes, this lens fills the entire frame with its distorted image, making it useful for both creative fisheye effects and practical applications like astrophotography.
Optical quality is excellent with sharp performance across the frame and well-controlled chromatic aberration. The multi-coating handles the extreme light angles inherent in fisheye designs effectively, reducing flare even when shooting towards bright light sources at the very edges of the 180-degree field of view.
Build quality follows Olympus's professional Zuiko Digital standards with weather sealing for outdoor use in challenging conditions. The lens is compact and well-balanced on Four Thirds bodies. The constant f/3.5 aperture provides adequate speed for the ultra-wide field of view and astrophotography applications.
On the used market, the Zuiko Digital 8mm fisheye can be used on Micro Four Thirds bodies with an adapter. For creative photographers and astrophotographers wanting a quality full-frame fisheye effect on the MFT system, it provides excellent optical quality with the weather sealing that outdoor work demands.
