The Fujinon HF12.5HA-1B is a very high quality C-mount lens designed for industrial applications like robotics and machine vision. It is intended to deliver quality images when mounted on cameras with as much as 1.5 megapixel resolution. Among its features this lens has locking focus and iris rings so it can operate consistently in jobs where the camera may experience significant vibration.

High Resolution Optics for High Rez Cameras
This lens was designed with quality glass and advanced anti-reflective coatings to produce detailed images in harsh environments. Fujinon developed this lens to work on cameras with up to 1.5 megapixel sensors.
Manual Adjustments
The HF12.5HA-1B is a completely manual C-mount lens designed for high quality images in potentially difficult applications. Often the manufacturing process can shake or vibrate machinery which can be an issue that needs to be managed when using video for quality control and production. This lens has locking iris and focus rings so those settings do not change over time.
Narrow Field of View
What good is a lens that doesn't aim decidedly at your target area of action? The HF12.5HA-1B delivers a medium narrow angle of view so you'll see exactly what you need to see and nothing more. This lens produces a 21° horizontal angle of view, with a 16° vertical angle. Its MOD (minimum object distance) is a very macro 0.1 meters or about 4 inches.

    Comments about Fujinon HF12.5HA-1B 12.5mm f/1.4 2/3" Fixed Focal Lens:

    I've deployed lots of these lenses (>50) in machine vision applications. For its class of lens, it's a decent value, but it has a moderate amount of barrel distortion (easily corrected), but along with it, a fairly strong curvature in its focal plane... not ideal if you have a planar target. My main gripe is that it's focus mechanism is touchy, and activating the the locking knob will skew the focus enough to matter if you are using a large aperture. If you have the space and the money, the 5MPix HF12.5SA-1 (and its cousins) series Fuji lenses are much cleaner optically and easier to use, but much more bulky.
