Summary

The Mitakon Speedmaster 45mm f/1.4 is a manual-focus lens for Fujifilm GFX and Hasselblad XCD medium-format cameras. At 45mm it covers an angle equivalent to 35-36mm on full frame, a versatile distance for environmental portraits, street and documentary work. Its 13-element, 11-group design includes two high-refractive-index elements, one ED and one aspherical, plus a floating-focus design that improves close-range performance. The Zhongyi Optics lens keeps a metal body and fully manual control.

The 11-blade clicked diaphragm lets you set the aperture from f/1.4 to f/16 and produces rounded out-of-focus highlights. Minimum focus is 0.45 m, the front filter is 62mm and the lens weighs 750 g without the hood. The GFX version measures 81 × 77.4mm and the XCD 77.6 × 85.8mm; neither has electronic contacts, so aperture and focus are set by hand and are not recorded in EXIF.

Its wide aperture makes it an interesting option for low-light portraits, weddings and night photography, where medium format holds detail and the blur is smooth. It also works for landscape and travel if you accept the weight and manual focusing. Against native GF lenses, this Mitakon Speedmaster 45mm f/1.4 offers an aperture-to-price ratio that is hard to match: $599.
