Fujinon CF25ZA-1S 1.1" 25mm f/1.8 Manual Iris C-Mount Lens, 2.5 Microm Pixel Pitch

Where high-resolution imaging is a necessity, the Fujinon CF-ZA-1S 1.1" 25mm f/1.8 Manual Iris C-Mount Lens stands out. This lens supports a large 1.1" type sensor with a 2.5 microm pixel pitch, equivalent to a 23-megapixel resolution, ensuring detailed and sharp images.

The lens is designed to provide an impressive relative illumination of over 90%, ensuring a clear and bright image from the center to the peripheral area. This is achieved through Fujifilm's original optical design that balances relative illumination and the chief ray angle (CRA), keeping the latter below 5 degrees.

The CF-ZA-1S series lens is particularly effective when using the F4 F-Stop, a common choice among users. Unlike other lenses that may require correction treatment to balance light and shade, this lens offers uniform illumination across the entire image, resulting in high-quality, low-noise images. This makes it an ideal choice for tasks requiring high reliability, such as inspections.

The lens also boasts Fujinon's "4D High Resolution" feature, which maintains uniform high resolution from the image center to the peripheral area, regardless of shooting distance or F-Stop. This feature, combined with the lens's support for 1.1" type sensor and 3.45 microm pixel pitch (equivalent to 12 mega-pixel), maximizes camera performance.

The CF-ZA-1S series lens is designed to support next-generation sensors, making it a future-proof investment. It excels with sensors like the IMX253 (1.1" type) and IMX255 (1" type), and is also compatible with 1.1" type sensor and 2.5 microm pixel (equivalent to 23 mega-pixel).

The lens's high-precision assembly technology and original detector help to minimize unilateral bokeh and single flaw. It also features Fujifilm's patented "vibration-resistance and impact-resistance" mechanical structure design, ensuring high resolution even under challenging conditions.

Despite its advanced features, the lens maintains a compact outer diameter of 39mm, making it a space-saving choice. It also offers high convenience and reliability with its internal mechanical focus, which ensures the overall length of the lens does not change when focused.

Additional features include three positioning holes for fixation of the Iris and focus on the lens body, an indication sign on the lens for optimal focus position at 50cm, and an "anti-separation structure" on the Iris and focusing screw knob. Each lens is also marked with a QR code for easy tracking and quality management.

In summary, the Fujinon CF-ZA-1S 1.1" 25mm f/1.8 Manual Iris C-Mount Lens offers a combination of high-resolution performance, advanced features, and compact design, making it a versatile choice for a wide range of imaging needs.
