Summary

The AstrHori 8mm f/2.4 is an ultra-wide manual circular fisheye lens engineered specifically for mirrorless medium format systems utilizing Fujifilm G and Hasselblad XCD mounts. Providing a designated focal length of 8mm and a sweeping 220-degree angle of view, the optical design projects a complete circular image circle across 44x33mm medium format sensors, delivering signature spherical distortion and dynamic environmental encapsulation. Its optical structure incorporates 10 elements arranged in 8 groups, featuring two extra-low dispersion (ED) elements and two high-refractive index (HR) elements to maintain strong contrast and suppress chromatic aberration across the broad imaging circle. Distinguished by an unusually fast maximum aperture of f/2.4 for an extreme circular fisheye, the lens excels in low-light environments, creative nightscapes, and immersive astrophotography. A minimum focusing distance of merely 10 cm (0.1 m) enables creators to position the front element directly adjacent to tiny foreground subjects, exaggerating spatial proportions while rendering a comprehensive visual panorama of the surrounding location. The manual aperture mechanism employs 10 diaphragm blades, providing smooth aperture adjustment down to f/16 and producing pleasant circular out-of-focus highlights when stopped down. Engineered with an all-metal anodized aluminum housing, the barrel provides dependable physical protection and reliable tactile handling during demanding commercial and outdoor shoots. Operating entirely without electronic contacts, it emphasizes deliberate manual precision, allowing cinematographers and photographers full tactile command over focus throw and iris positioning. Expanding the creative boundaries of medium format photography, this distinct optic showcases the specialized engineering ethos of AstrHori for creators seeking singular optical expression.

Pros & Cons

Pros

Massive 220-degree circular field of view optimized for 44x33mm medium format sensors
Bright f/2.4 maximum aperture advantageous for low-light creative imaging and nightscapes
Ultra-close minimum focusing distance of just 10 cm allows dynamic close-up compositions
Advanced optical construction featuring 2 ED and 2 high-refractive glass elements
Precision all-metal mechanical construction with tactile, well-damped focus and aperture rings

Cons

Pure manual focus and aperture control with no electronic communication or EXIF data transmission
Circular fisheye perspective produces strong geometric distortion unsuitable for standard documentary framing
Bulbous front glass element does not accommodate front screw-in filters
