Fujinon's Latest Broadcast Glass is 4K HDR-Ready

With the new UA24x7.8 compact zoom, Fujinon, the optical division of FujiFilm, takes aim at the live broadcast 4K market.

Fujinon continues to expand the options in the 4K, 2/3" broadcast market with the highly compact, 24x zoom UA24x7.8 zoom lens. While the company has 27x and 107x zooms already on the market, those are intended for studio use (with the 107x coming in at a reasonable $198k). A 24x zoom is designed for field use, and coming in at under five pounds is an exciting development for shooters in the news and sports arenas. It appears to be one of the smallest and lightest 4K-capable broadcast lenses available.

What does HDR-ready mean in terms of a lens? The big driver for HDR is in the sensor and the signal path. You need a sensor capable of seeing that side of a latitude, and also a signal path that can maintain that wide latitude all the way through broadcast. The lens isn't traditionally thought of as an important part of HDR, but lenses can affect contrast. It's especially common to see lenses that "flatten out" or lower contrast on imagery when wide open, and have an increase of contrast as they stop down. This isn't as common with broadcast lenses, but HDR recording and delivery will require maximum performance and consistent contrast reproduction throughout the aperture range, so it's good to hear that HDR is part of the design and testing considerations that FujiFilm is putting into this lens.

4K means nothing. What sensor size it covers is more important. My 1/3 inch sensor phone shoots 4K.

This lens is intended for 30K to 60K USD broadcast cameras. You don't really want to compare those to your smartphone, do you?
These 2/3" cameras for one have 3 sensors with an optical prism, so no Bayer patterns. And their sensors are real 4K, that's why they are expensive.
What film buffs often don't understand: bigger sensors are useless in some areas like sports, because you cannot get the tele and zoom range like with a 2/3"
