【3X Zoom Ratio】This cine lens covers a very practical zoom range from wide-angle to medium telephoto (28mm to 85mm), which allows filmmakers to go out for filming all in one package. This zoom lens features advanced parfocal design, which allows the focus remains unchanged throughout the zoom range, so the story will be consistent and attractive.

【8K Resolution】The image is exceptionally sharp and the overall look is crystal clear. The transition is smooth and natural with some pleasing bokeh in the background. Minimal Focus breathing is unnoticeable especially when you have a moving subject or the camera panning, effectively keeping your audience from distracting.

The lens features a step-less aperture ring and a long focus throw of 259° for accurate and smooth iris adjustment and focus pulling. The focus ring features a dual scale with both feet and meters, making this lens super nice to operate and use.
