ZY Optics releases the Mitakon Speedmaster 65mm f/1.4, designed specifically for Fujifilm GFX cameras
Shenyang China, Nov 30, 2018 – Zhongyi Optics (ZY Optics) has released a new Mitakon Speedmaster 65mm f/1.4 for Fujifilm G mount, the fastest standard-length native lens for Fujifilm GFX cameras.
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 minimises 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 minimises 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.
Pricing & Availability
Mitakon Speedmaster 65mm f/1.4 is now available to ship. The Recommended Retail price is USD 799/pc.
