Mitakon Speedmaster 65mm f/1.4 lens for Fujifilm GFX Mirrorless Medium Format

December 3, 2018 | Mark Goldstein | Compact System Camera , Lenses | Comment |

Zhong Yi Optics has released the first third-party lens for Fujifilm GFX cameras. The new Mitakon Speedmaster 65mm f/1.4 lens provides a focal length equivalent to 46mm in 35mm terms. It's also the fastest lens currently available for the Fujifilm G mount.

Offering a natural perspective (50mm field-of-view) along with a fast maximum aperture, the Mitakon 65mm f/1.4 is a versatile normal focal length prime characterised by its bright f/1.4 aperture to suit working in low-light conditions. It also affords a great degree of control over depth-of-field for isolating subjects from the background and producing selective focus effects.

A carefully-designed 11 elements in 9 groups optics system with 2pcs of HRI (High Refractive Index) & 2pcs of UD (Ultra-low dispersion) elements successfully minimizes the chromatic aberrations and delivers exceptional image quality to meet the demanding 51.4MP sensors.

A rounded nine-blade diaphragm helps to produce a softly diffused out-of-focus rendering (bokeh). The enclosure of the lens is made of metal to strengthen its durability.

The built-in retractable lens hood design successfully prevents the stray lights from entering the frame and at the same time, saves the trouble of losing the lens hood when you are on-the-go.
