Sony ha presentado la segunda camara de formato completo de su línea reflex, es decir full frame, y que esta por debajo de las prestaciones de la a950.
Ahora que es lo especial de esta camara, pues que es la primera reflex, que se situa en precio en torno a los $ 2000, lo que la hace la camara full frame mas barata del mercado, y que puede ser un punto de inflexion, en la llegada de este tipo de sensor a los mercados; como en su día lo hizo la Canon EOS 300D, la primera reflex digital situada por debajo de los $ 1000, lo que hizo que las camaras de linea baja de muchas marcas empezaran a bajar en precio.
Ahora nos queda esperar si el rumor de la Canon 7D (full frame) es cierto, iguale o sea mas barata que la a850.
