Cuando recorremos las l\u00edneas de objetivos de alta gama, a veces nos preguntamos porqu\u00e9 los precios son tan elevados. Por lo general si hablamos de tele zooms estaremos hablando de miles de d\u00f3lares y esto se debe a la tecnolog\u00eda tanto \u00f3ptica como electr\u00f3nica que poseen en su construcci\u00f3n.<\/p>\n
Los cristales que se producen para estos objetivos son de la m\u00e1s alta pureza y algunos, como el caso de Canon tiene cristales de fluorita.<\/p>\n
<\/a><\/p>\nLa Fluorita, que se caracteriza por una dispersi\u00f3n muy baja de la luz, es capaz de combatir la aberraci\u00f3n residual que no son capaces de eliminar adecuadamente los vidrios \u00f3pticos convencionales. Canon fue capaz de crear artificialmente en los a\u00f1os sesenta el vidrio de Fluorita y de producir los primeros elementos de Fluorita para los objetivos intercambiables para c\u00e1maras r\u00e9flex de un s\u00f3lo objetivo. En la d\u00e9cada de los setenta, Canon produjo los primeros elementos de lentes UD (Dispersi\u00f3n ultra baja) que incorporan vidrio \u00f3ptico de baja dispersi\u00f3n. Esta tecnolog\u00eda fue mejorada a\u00fan m\u00e1s para crear las lentes S\u00faper UD en la d\u00e9cada de los noventa. Actualmente se utilizan diversas combinaciones de elementos de Fluorita, UD y S\u00faper UD en los s\u00faper teleobjetivos de la serie L, objetivos zoom tele y objetivos angulares.<\/p>\n <\/p>\nA continuaci\u00f3n unos videos de la construcci\u00f3n de estos objetivos. en donde se justifica sobremanera el costo de los m\u00edsmos.<\/p>\n <\/p>\n<\/embed><\/div>\n <\/p>\nEl armado final de un objetivo Canon de 500mm de la serie L.:<\/p>\n <\/p>\n <\/p>\n<\/embed><\/div>\n","protected":false},"excerpt":{"rendered":"Cuando recorremos las l\u00edneas de objetivos de alta gama, a veces nos preguntamos porqu\u00e9 los precios son tan elevados.
