ZY Optics’s New Mitakon 45mm f/1.4 Lens
ZY Optics (aka Zhongyi) has announced the new Mitakon Speedmaster 45mm f/1.4, a manual-focus prime lens for Fujifilm GFX and Hasselblad XCD medium format cameras. The lens is designed to cover 44 × 33mm medium format sensors and offers a field of view roughly equivalent to a 35–36mm lens on full-frame. With a maximum aperture of f/1.4, it is also much faster than most native medium format lenses currently available, although you will have to work without autofocus. The aperture ranges from f/1.4 to f/16, with an 11-blade diaphragm and a clicked aperture ring. Both the Fujifilm GFX and Hasselblad XCD versions come with native mounts, meaning there is no need for an adapter.
On the inside, the lens uses 13 elements arranged in 11 groups, including two high-refractive-index elements, one extra-low dispersion (ED) element and one aspherical element. Zhongyi has also included a dual floating-element focusing system, which is supposed to help maintain sharpness and control optical aberrations at different focusing distances. The lens can focus as close as 45cm and accepts 62mm screw-in filters. One thing worth mentioning is that the lens has no electronic contacts, so there is no electronic communication between the lens and camera. That also means aperture information will not automatically be recorded in the photo's metadata.
The lens itself has a full-metal body and weighs around 750g without the hood. There are also some small differences in size depending on the mount. The Fujifilm GFX version measures 81 × 77.4mm, while the Hasselblad XCD version comes in at 77.6 × 85.8mm. The Zhongyi Mitakon Speedmaster 45mm f/1.4 is priced at $599 for both mounts.
