Summary

The Zhongyi Optics Mitakon Speedmaster 80mm f/1.6 is an ultra-fast manual-focus short-telephoto prime lens crafted specifically for Fujifilm G (GFX) medium format mirrorless cameras. Combining an 80mm focal length (providing a versatile 63mm field of view in 35mm full-frame terms) with a blazing-fast f/1.6 maximum aperture, it stands as one of the fastest native medium format optics available, delivering extreme subject separation and dreamy background melt.

The optical architecture comprises 10 elements in 6 groups, utilizing 4 High Refractive Index (HRI) elements alongside 1 Ultra-low Dispersion (UD) element to suppress chromatic fringing and optimize central contrast and acuity across high-resolution medium format digital sensors. The rounded 9-blade diaphragm produces beautifully circular out-of-focus highlights, while the de-clicked aperture ring and extended manual focus throw provide velvety, highly predictable tactile operation for portraiture and creative cinematography alike.

Encased in a robust all-metal barrel with clear engraved distance and depth-of-field markings, the lens accepts standard 77mm front screw-in filters. With a solid weight of 850g, an outer diameter of 82mm, an overall length of 100mm, and a close minimum focusing distance of 50cm (500mm), it offers medium format photographers a distinctive, expressive visual signature with exceptional light gathering and handcrafted mechanical precision.
