Fujinon Premista: all the benefits of a large format with a surprising quality of optical sensor En NAB 2019, Fujifilm dar a conocer sus nuevos objetivos Premista 28-100mm, que combina dise os pticos y mec nicos de primer nivel con las ltimas tecnolog as de fabricaci n, y Premista 80-250mm, un teleobjetivo con una distancia focal de 80-250mm.

Fujifilm dar a conocer en NAB 2019 en Las Vegas sus nuevos objetivos Fujinon Premista 28-100mmT2.9 (Premista 28-100mm), que combina dise os pticos y mec nicos de primer nivel con las ltimas tecnolog as de fabricaci n; y el Premista 80-250mmT2.9-3.5 (Premista 80-250mm), un teleobjetivo con una distancia focal de 80-250mm,

Con esta dos nuevas soluciones, el fabricante ofrece todos los beneficios de un sensor de gran formato con una calidad ptica sorprendente. En los ltimos a os, los cinemat grafos han comenzado a trabajar cada vez m s con c maras de cine equipadas con un sensor de gran formato para la producci n de im genes cinematogr ficas y comerciales buscando un efecto bokeh natural y sugestivo, con poca profundidad de campo y un amplio rango din mico. Si bien existen lentes en el mercado compatibles con el sensor de gran formato, ha crecido la demanda de lentes con zoom que cubran una amplia gama de distancias focales y que ofrezcan versatilidad con la m s alta calidad ptica.

Debido a estas demandas, Fujifilm lanzar el objetivo Premista 28-100mm en agosto de 2019 combinando dise os pticos y mec nicos de primer nivel con las ltimas tecnolog as de fabricaci n. Esta introducci n ser seguida en 2019 por el lanzamiento de Fujinon Premista 80-250mm, un teleobjetivo con una distancia focal de 80-250mm, por lo que juntos cubrir an los rangos de distancia focal que se utilizan de forma m s frecuente (de 28 mm a 250 mm).

El Premista 28-100mm tiene una apertura constante de T2.9 en todo el rango de zoom y presenta un efecto bokeh natural y sugestivo con poca profundidad de campo gracias a un nuevo dise o de iris de 13 hojas y un amplio rango din mico, que son beneficios de un sensor de gran formato.

Se trata de una lente zoom est ndar que cubre una distancia focal de 28-100mm. Esto equivale a 6 lentes fijas prime , lo que ahorra tiempo y gastos causados por el cambio frecuente de lentes. Gracias a la adopci n de una lente asf rica de gran di metro y un nuevo sistema de enfoque/zoom, la Premista logra una calidad ptica sorprendente desde el centro hasta las esquinas, lo que permite al director de fotograf a capturar texturas tanto en personas como en objetos. El dise o de la lente contribuye a la amplia gama din mica al suprimir las aberraciones crom ticas y las distorsiones no deseadas gracias al software de c lculo ptico original de Fujifilm.

compact design El dise o de Premista combina un peso ligero de 3.8 kg y un tama o compacto, as como la durabilidad de las lentes Fujinon, incluso en las duras condiciones de uso profesional. La lente de zoom es especialmente conveniente cuando se usa en una gr a o en un helic ptero donde es dif cil acceder a la lente. Adem s, las lentes Premista logran una calidad constante, ya que todas las piezas clave se fabrican con tolerancias de nivel de micras y se ensamblan con precisi n. El anillo de enfoque tiene un ngulo de rotaci n de 280 grados con una torsi n suave gracias a los trabajadores altamente calificados de Fujifilm.

Gracias a haber incorporado una lente asf rica de gran di metro fabricada por una m quina de rectificado de alta precisi n, logra una calidad ptica sorprendente y una distorsi n baja desde el centro hasta los bordes. Permite la captura de texturas tanto en objetos y en personas al mejorar la resoluci n de los objetos de alta y baja frecuencia con un equilibrio bien definido.

Adem s, al combinar los sistemas de enfoque y zoom recientemente desarrollados, ofrece im genes claras y n tidas con m nimas aberraciones de color, independientemente de la posici n del zoom o la distancia de los sujetos.

Las aberraciones crom ticas y las distorsiones no deseadas se eliminan bien gracias al software de c lculo ptico interno. Funciona bien con el alto rango din mico de un sensor de gran formato.

El color es natural y neutro al devising grass elements and coatings. Se puede combinar con la l nea actual de lentes de cine de Fujifilm para simplificar la gradaci n de color que se requiere cuando se usan m ltipleslentes.

En cuanto a su dise o cabe rese ar tambi n que el cilindro de la lente combina una gran durabilidad incluso en las duras condiciones de uso profesional y un cuerpo liviano. Su longitud de 255 mm es un 28% m s corta y su peso de 3,8 kg es un 46% m s ligero que el Fujinon HK4.7 18 que es compatible con las c maras con sensor Super 35 mm.

La lente zoom consta de casi 30 elementos de lente y su estructura es compleja, por lo que las partes mec nicas se fabrican con tolerancias de nivel de micras. Para lograr una calidad constante, las piezas clave se ensamblan con precisi n. La torsi n suave para cada anillo se logra gracias a los trabajadores altamente calificados de Fujifilm, algo que no se puede lograr ni siquiera con una mecanizaci n de ultra-precisi n.

El Premista 28-100mmT2.9 cubre una distancia focal de 28-100mm, que equivale a casi 6 lentes primarias. Ahorra tiempo y gastos causados por el frecuente cambio de lentes.
