The Fujinon 4K Premier UA107X8.4 107x Zoom with OISfrom Fujinon 4K Premier UA107X8.4 107x Zoom with OISis box-style field lens featuring a high 107x zoom range and 4K optical-quality imaging. This lens has an 8.4-900mm zoom with a 16.8-1800mm range when using the built-in 2x extender. Its OS-TECH optical image stabilization is designed to produce steady shots, even at long ranges, and can be switched on and off. Aspherical elements, a multi-layer lens coating, and extra-low dispersion glass help to produce an optimal image. The 4K Premier UHD UA107X8.4 has a 9-blade iris for attractive bokeh and natural-looking bright objects. Crisp, high resolution images with detailed contrast levels, HDR (high dynamic range), and true blacks are achieved with the use of optical simulation technologies, extra-low dispersion glass, minimization of aberrations, and advanced HT-EBC lens coating.

This versatile box-type 107x zoom includes an array of features for optimal 4K UHD image-capture. With the push of a button, the 0.7 second QUICK ZOOM feature allows the operator to zap into a telephoto shot to check focus, then zoom back out to the original frame. An RS-232 port connects the lens to a PC or other control device. Two-shot presets save the zoom and focus parameters for your chosen position. Additional functions include the FIND self-diagnosing lens electronics system, automatic focus "breathing" compensation, and lens data output for use with virtual/compositing systems. As with all Fujinon field lenses, the 4K Premier UHD UA107X8.4 zoom incorporates a fixed front element to protect the front focus element group while also reducing dust contamination.

Related Questions and Answers

Q: 1. Is this lens parfocal? When I try to use it, the focus doesn't hold throughout the zoom

A: The Fujinon 20x Zoom Lens with Optical Image Stabilizer (B&H# FUXA20X41BMA) certainly has many fine qualiities, but it is not parfocal.

Q: 2. Will this cover Arri LF?

A: Unfortunately the Fujinon 4K Premier UHD UA107X8.4 lens is meant for 2/3 sensor cameras and would not be a good fit for the large format sensor of the ARRI LF.

Q: 3. Would this work with Pana HPX372EN (Stock Lens Fujinon XT17sx45BRMK1 17x 4.5mm)? I'm looking for something with more zoom for the camera.

A: If you are referring to the HPX-3700 then we are afraid not. That is a 2/3" camera and this lens only covers 1/3" sensors. So that we may best assist you finding the proper product for your needs feel free to email us directly at askbh@bhphoto.com.

Q: 4. We have the JVC GY-HM850U. Would this lens be considered an upgrade from the stock lens that came with the camera? If yes...in what ways (better picture, wider/not as wide. etc.)? I'm not much of a lens expert. Just wondering. Thanks.

A: I would say it is a wash though I would bow to expert opinion from Fuji. One lens is a little wider and the other a little tighter. I suspect that image quality is pretty much the same. I would think you do fine saving your money.

Q: 5. is this compatible with JVC GY-HM710U? Looking for a better zoom than the 14xcanon lens that came with it.

A: Yes, this lens should work well with the GY-HM710U.

Q: 6. What is the camera mount size on this? C mount?

A: This is a 1/3" B4 lens for Panasonic/JVC Broadcast cameras.

Q: 7. will this lens work on a Panasonic AG HPX300P?

A: Yes, the Fujinon 1/3" B4 mount 20x Zoom Lens with Optical Image Stabilizer would be compatible with the Panasonic AG-HPX300P.

Q: 8. If using this with a Super Cmos sensor would there be a crop factor? Can you offer an adapter to use with the Canon C100? Thanks

A: We are not aware of any adapter solution that would allow you to use this lens with a Canon C100 camera.

Q: 9. Is there a rear control for this lens. I'm using ursa g2?

A: No, there is no rear control for the Fujinon 20x Zoom Lens.

Q: 10. can this be used on an HD ENG/studio camera like the hitachi Z-HD5500? does the 4K even matter? shouldn't it still work on an HD 2/3" B4 mount camera? thanks!

A: Yes. As long as the Hitachi Studio Adapter for use with all Broadcast box, compact studio and hand-held 2/3-inch bayonet lenses are in place.
