Introducing the NiSi 35mm ATHENA Prime Full Frame Cinema Lens T1.9. This lens is expertly engineered for maximum micro-contrast control and features ultra-low chromatic aberration, delivering unparalleled image quality with intricate detail. With a large aperture of T1.9 and a soft bokeh effect, it provides beautiful background separation, making it an ideal choice for capturing stunning images and videos. The ATHENA Prime Lens Series is equipped with a rear filter mount, which provides a more flexible workflow and creative control for filmmaking. Filmmakers can easily add ND filters, polarizers, or other filters to achieve their desired look without having to attach filters to the front of the lens. This feature also makes it easier to swap filters quickly and efficiently, saving time and reducing the risk of lens damage. The lens has been designed to minimize focus breathing, ensuring that the change in field of view when adjusting focus from the minimum focus distance to infinity is extremely small. This feature is particularly important for filmmakers who need to maintain a consistent field of view when focusing on their subject. With the ATHENA Prime Series lens, filmmakers can achieve precise focus pulls and maintain a consistent look throughout their shots. In addition, the NiSi ATHENA Prime 35mm lens is matched in weight and size with other lenses in the series, eliminating the need for rebalancing on a gimbal when switching between lenses. The 77mm filter thread and matched aperture and focus rings across the range also make it easy to use lens accessories such as filters and focus gears. The focus ring features 300° of rotation with fluorescent focal scales for precise focus pulls, making it easier for filmmakers to achieve their desired focus. The NiSi ATHENA Prime Full Frame Cinema Lens with a 35mm T1.9 focal length is a versatile and high-quality lens that offers unparalleled image quality, flexibility, and creative control for filmmakers. Whether you're shooting a feature film or a music video, the ATHENA Prime Series will help you easily achieve your creative vision.
