1.Core optical performance
· T2.0 Bright Large Aperture: Utilizes a T2.0 large aperture (equivalent to F2.0 light flux), offering significant advantages in low-light conditions, enabling deeper depth of field and a larger focus area, while effortlessly creating soft bokeh and enhancing the cinematic atmosphere.
· Full-frame High Resolution Imaging: Designed for full-frame sensors, featuring a newly designed optical and mechanical structure. The lens group consists of 6 groups of 5 optical elements, combined with high-quality ED (low dispersion) and high refractive index glass, ensuring rich picture details, effectively reducing color bias, and enhancing the artistic quality of the image.
· 12 Aperture Blades: Equipped with 12 aperture blades, even when the aperture is contracted, it can maintain a round and soft out-of-focus light spot, with a smooth transition, resulting in a vivid and natural image without being stiff.
· Almost “Zero” Shutter Effect: By effectively controlling the breathing effect during focusing, the image perspective remains stable when re-focusing, avoiding the “breathing” effect in the picture caused by focus changes, a necessary feature for professional video shooting.

2. Exclusive Design for Film Shots
· 270° ultra-long focusing stroke: With a 270-degree ultra-long focusing rotation angle, it can achieve extremely fine and precise focus control, meeting professional focusing requirements.
· Industry-standard focusing gear ratio: The focusing ring and aperture ring both adopt the 0.8 MOD gear design of the film industry standard, which can perfectly adapt to various focusing devices, motors and accessory systems.
· Infinite aperture ring: The aperture ring adopts an infinitely adjustable design, with smooth rotation without any gear sensation, enabling smooth and flicker-free exposure changes during video shooting.
· Unified color in the series: The spectral series lenses (35mm/50mm/85mm) have unified color balance and color temperature performance. When changing lenses or shooting positions, the color remains consistent, significantly reducing the workload of post-production color grading.

3. Workmanship and Control Design
· All-metal sturdy body: The lens features a sturdy metal body and metal snap, with precise manufacturing ensuring reliable protection for the internal optical components. Even in complex on-set environments, it can handle the situation with ease.
· Dual focusing scales: Both sides of the lens are equipped with focusing distance scales, marked in both meters and feet, making it convenient for photographers to read the parameters from different angles.
· 82mm universal filter aperture: It adopts 82mm filter threads, compatible with mainstream film-grade filter systems and shade cups, facilitating unified accessory management.
· Moderate close-up capability: The closest focusing distance is 48 centimeters (approximately 18.9 inches), capable of meeting the shooting needs of certain close-up lenses.

4. Compatibility and User Reviews
· Multiple mount options: Offers a variety of mainstream micro-DSLR mount options such as Sony E, Nikon Z, Canon RF, and L mounts.
· Weight and size: The weight of the lens ranges from approximately 690 grams to 793 grams (slight variations depending on the mount), with a diameter of about 90mm and a length of approximately 102mm. It is a compact and lightweight model among film lenses.
· User reviews: Overseas users generally rate it above 4.5 stars, described as “an excellent entry-level film lens”, “highly cost-effective”, and “perfectly compatible with FX3 and other film cameras”. Users particularly praise its smooth operation feel, excellent image quality, and the color matching of the series of lenses.
· Usage tips: After installing the lens, you need to enable the “No Lens Release Shutter” mode in the camera menu; otherwise, you won’t be able to press the shutter to take pictures.

5. Product Positioning
· Target Audience: Suitable for video creators, independent filmmakers, Vlog bloggers, and photographers who are transitioning from photography to video shooting. As an entry-level full-frame cinema lens, it offers the core functions of a professional cinema lens at an affordable price.
