Designed for cameras having pixels as small as 3.45 µm, the HF25XA-5M quality C-mount lens performs well when combined with modern image sensors. This lens has a 13.4 mm image circle, although performance is reduced outside the typical 11 mm (2/3") circle. We recommend it for 2/3" and smaller sensors having 3.45 µm pixels, as well as for sensors up to 13.4 mm (1/1.2") in size having 4.5 µm or larger pixels. Examples include the Python 1300, Python 2000, IMX249 and IMX174 image sensors.
Fujinon's precision focusing mechanism has roughly 310 degrees of rotation, making for easier focus adjustment than many otherwise competitive lenses. Thumb-screws lock down both focus and aperture. The clever design lets you choose three possible locations for the thumb-screws, ensuring they stay out of the way while remaining accessible. The lens has a relatively short Minimum Object Distance, enabling design of more compact imaging systems.
