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 / 35/ 50mm 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 physicalsize 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.
Premier Optical Performance
The color contrast and sharpness of the images are much more well-defined than other lenses with similar specifications and price ranges. The T1.0 lenses offer a pleasant rendering of a cinematic look. This series strikes to give natural colors with a hint of vintage vibes. And the color is consistent for different focal lengths.
