The Fujinon HA25x11.5BERD is a 2/3" telephoto lens with 25x optical zoom. The lens comes with a 2x extender for instant telephoto. Known for their high build quality and precision optics, Fujinon lenses have become the industry standard for professional video applications all over the world.

This lens will not only resolve images for high-definition acquisition, it's also equipped with a wide array of extra features such as QuickZoom technology. Quickzoom makes it easy to verify focus by allowing instant telephoto zoom capability.

Many high-definition cameras are hamstrung by insufficient optics. Electronic News Gathering (ENG) lenses traditionally have been built to accommodate standard-definition. This lens is designed specifically with high-definition in mind. The optics increase fidelity, making sure HD footage is crystal clear.

For instant close-up shots, the lens has a switch that inserts an element that doubles the focal length at any point in the zoom range. Instead of using the zoom function, the extender gives immediate close-up images.

The lens has an added zoom capability when using the QuickZoom switch. At the touch of a button, the lens can move to full telephoto in less than a second. This provides a no-hassle way of verifying focus.

The lens element design fitted for the internal focus mechanism greatly reduces aberrations and image distortions. These advances contribute to more balanced imaging from center to edge throughout the aperture range.

Q: 10. Can this lens be used with the Blackmagic HD Studio camera?

A: The Blackmagic Design Studio Camera HD has a sensor that is much larger than what this lens can cover. In other words, if you were to mount the XT17sx45BRMK1 17x 4.5mm on the camera somehow, you would get a centered circular image surrounded by black. What you need are lenses that create large enough image circles for the camera's sensor.Here are two affordable powered zoom lenses by Panasonic and Olympus that will mount directly onto the camera and you will be able to power zoom with them.Just for your information, I added a Canon zoom. It is one of the lenses that Blackmagic used in their brochures about the camera. You also need a lens mount adapter for it to attach to the BMSC.
