All 4 focal lengths have a different coverage and are designed for different cameras. The 17mm, 25mm and 35mm all comes with a Micro Four Thirds mount, making them a perfect ultra-fast and compact option for Panasonic GH5, Z-Cam E2 and Pocket4k. The 35mm, instead, has a Super35 image circle and comes with Canon RF, Sony E and Fuji X mount. The new 50mm, on the other hand, is designed for full frame EF/PL cinema cameras, making it the world’s fastest PL-mount cinema lenses covering Arri Alexa LF and Red Monstro sensors. ZY Optics is currently working to add more focal lengths to the 3 line-ups (i.e. Micro Four Thirds, Super 35 and Full Frame) and more details will be released soon.
Buttery Smooth & Refined Bokeh Rendering
The ultra-fast T1 aperture and close min. focusing distance enables the lens to produce buttery smooth and refined bokeh rendering. 9-blade circular aperture mechanism contributes to a pleasing round bokeh when the lenses are used wide-open. Perfectly separating the subject from its background, the lenses enable a creation of a look unparalleled by conventional lenses.
Minimal Focus Breathing
The Zhongyi T/1.0 series lenses are designed to suppress the focus breathing to the minimal, allowing focus pull without compositions changed. The ultra-fast T1 aperture also facilitates shooting at low-light condition.
Extraordinary Mechanical Built
A unified front diameter and gear position of the 17 / 25 / 35mm lenses make the work with focus motor and matte box much easier. Operators are thereby free from frequent re-adjustment of the settings. The internal focus design means the physical
size of the lens stay unchanged throughout the entire focus throw. The seamless lens gear and long focus throw with precise scale markings allow accurate control of focus point even with extremely shallow depth of field at T1.0.
The 50mm has a relatively bigger form factor with its full frame coverage and longer flange design. It is specially designed to match with professional large format cinema cameras in PL / EF mount.
