Designed for pixels as small as 2.1 microns
Precision focusing threads
Short minimum object distance
Anti-shock & vibration per JIS 60068-2-6
Designed for cameras having pixels as small as 2.1 µm, the Fujinon HF2518-12M lens performs well when combined with modern CMOS 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.
