Fujinon ushers in a new era in lens design with two new 8K and UHD optics and innovative stabilization technologies Si en 2015, la multinacional sorprendi con el lanzamiento de la serie UA para 4K UHD, que incluye ya hoy una quincena de modelos, ahora Fujinon da el campanazo con las nuevas pticas 8K Ultra HD con zoom broadcast HP66 15.2-ESM (HP66x15.2) y HP12 7.6ERD-S9 (HP12x7.6).
Gordon Tubbs and Toshihisa Iida, vicepresidente y director general de la divisi n de soluciones pticas en Fujinon, junto a director de marketing Thomas Fletcher han sido los encargados de presentar virtualmente las nuevas soluciones del fabricante japon s que pese a la pandemia de coronavirus COVID-19 contin a al pie del ca n.
Si en 2015, la multinacional sorprendi con el lanzamiento de la serie UA para 4K UHD, que incluye ya hoy una quincena de modelos, ahora Fujinon da el campanazo con las nuevas pticas 8K Ultra HD con zoom broadcast HP66 15.2-ESM (HP66x15.2) y HP12 7.6ERD-S9 (HP12x7.6).
Ambas son fruto de dos avanzadas tecnolog as, tanto desde el punto de vista del dise o ptico, con un procesamiento y ensamblaje preciso, como con respecto a la ciencia del color que permiten una reproducci n nica de la imagen.
Fujifilm saca provecho de sus tecnolog as pticas de vanguardia en la producci n de v deo, para expandir a n m s su l nea de lentes de broadcast de alto rendimiento, incluidas las lentes compatibles con c maras de transmisi n 8K.
Al empe o que desde los a os 70 tiene el fabricante en cuanto a sus chequeos de calidad en la fabricaci n de los cristales, ahora se unen tecnolog as de pulido Nano-level que hacen posible que la calidad de sus lente 4K y 8K sea nica.
Las nuevas lenes responden a los principios de la m s alta calidad, versatilidad tanto en versiones de mano como box lenses, y usabilidad con el desarrollo de nuevas herramientas que ayudar n al operador en su trabajo como RBF, ARIA y controles de la lente. Todo eso, sin olvidar el soporte, feedback continuo y formaci n que caracteriza a Fujinon.
En cuanto a la nueva HP66 15.2 es una lente tipo caja que alcanza la distancia focal m s larga del
mundo de 1000 mm y ofrece el aumento de zoom m s alto de 66x.
Por su parte, la HP12 7.6 es una lente de tipo port til que cubre el rango de distancia focal m s amplio del mercado, de 7,6 mm a 91 mm.
El HP66 15.2 y el HP12 7.6 se lanzar n en el verano de 2020 y el oto o de 2020,respectivamente.
Hoy en d a, el uso de video de alta definici n se est extendiendo a nivel mundial, especialmente en la cobertura de deportes en vivo y programas documentales. Se espera que el video de ultra alta definici n (UHD) en 4K y 8K prolifere a n m s. Tanto en el Mundial de Baloncesto de Beijing en 2019 como en varios eventos deportivos producidos por BT Sports ha quedado patente ya potencial de lentes Fujinon al trabajar con resoluciones 8K.
Las HP66 15.2 y HP12 7.6 ofrecen una resoluci n ultra alta que se combina con una reproducci n v vida de colores y un alto contraste para producir una rica gradaci n tonal en alto rango din mico (HDR).
Las lentes se pueden usar con la unidad de demanda de posici n de enfoque Fujinon EPD-51A-D02 / F03, lanzada en marzo de este a o, para lograr un enfoque preciso. La combinaci n facilita la grabaci n de videos de 8K, lo que exige un nivel avanzado de precisi n de enfoque.
Las lentes usan elementos asf ricos y de fluorita para controlar la distorsi n de la imagen y la reducci n de luz en las esquinas de la imagen tanto como sea posible. El uso del sistema de enfoque flotante, que controla m ltiples grupos de lentes de acuerdo con la distancia de disparo, minimiza las fluctuaciones en el rendimiento ptico, causadas por los cambios de esta distancia, ofreciendo im genes n tidas desde el primer plano hasta el infinito. El uso del diafragma de 9 hojas logra adem s una forma de apertura m s cercana a un c rculo perfecto lo que facilita un bokeh natural en los videos .
El codificador de 16 bits se ofrece de serie con los objetivos, proporcionando una salida de datos en alta resoluci n, incluidas las posiciones de enfoque y zoom. Permite la conexi n con varios sistemas, como un estudio virtual para combinar gr ficos de ordenador con secuencias de video en vivo.
UA107x, primera lente 4K de baja con Advanced Focus Fujinon cuenta ahora tambi n con la UA107x8.4 AF (Advanced Focus) 4K, la primera lente de caja de 4K del mundo que cuenta con la funci n Advanced Focus.
La UA107x8.4 AF incorpora un sensor de autoenfoque de detecci n de fase de nuevo desarrollo, consiguiendo im genes r pidas y n tidas con una velocidad de respuesta de tan s lo 0,45 segundos y presumiendo de una capacidad excepcional para seguir a un sujeto en movimiento. El objetivo tambi n cuenta con el mecanismo de estabilizaci n de imagen patentado por la empresa y un zoom de ultra ampliaci n de 107x que cubre distancias focales de 8,4 mm a 900 mm (1800 mm con 2x).
Adem s de utilizar elementos asf ricos y fluorita para controlar eficazmente varios tipos de aberraciones, el revestimiento multicapa nico de la compa a (revestimiento de haz de electrones de alta transmisi n) aumenta la tasa de transmisi n de la luz, lo que permite ofrecer una reproducci n de colores vivos, as como una rica gradaci n tonal basada en el HDR, incluso bajo un sol brillante o al atardecer.
Con la nueva lente, el operador no tiene que preocuparse por el enfoque en producciones cr ticas en 4K.
Nueva generaci n de estabilizaci n En la conferencia de prensa virtual de este 16 de abril, Fujinon ha dado a conocer una nueva generaci n de tecnolog as de estabilizaci n que ir incorporando en diferentes modelos de pticas.
Entre ellas, destaca la nueva funci n RBF (Remote Back Focus) que mejora la estabilizaci n cuando se usa en gr as, estadios, giroscopios, gr as Es de destacar que el RBF podr ser operado directamente por el personal e
