Las pruebas
Rendimiento
Lo que más nos sorprendió al revisar nuestras pruebas fue la batería. Está en el percentil 96 y en el mundo real aguanta más de 600 disparos sin pestañear, algo bestial en full-frame. El enfoque automático con 693 puntos y detección ocular es otro puntazo: caza caras y ojos como un perro de presa, incluso con poca luz. Eso sí, la ráfaga de 10 fps está bien pero no es líder, y el sensor de 24 MP es simplemente correcto, sin alardes. Para producto o recortes drásticos se queda justo, pero para el 90% de situaciones es más que suficiente.

Frente a la competencia
Frente a la Canon EOS R6 Mark III, la Sony aguanta por precio y batería, pero la Canon le saca ventaja en ráfaga y vídeo 4K 60p sin recorte. Si el vídeo es tu prioridad absoluta, la Panasonic LUMIX GH7 es otra liga con sus codecs internos y 4K120, aunque su sensor es Micro Cuatro Tercios. Para foto híbrida y presupuesto ajustado, la a7 III sigue siendo la opción más sensata, pese a ser la veterana del grupo.

Precio
Relación calidad-precio
El rango de precios es amplio, desde 1125 hasta 2198 dólares según el vendedor. Si la pillas en el extremo bajo, como en B&H con el kit básico, la relación calidad-precio es ridícula. Por menos de 1200 te llevas una full-frame con un enfoque y una batería que humillan a muchas cámaras más caras. Si pagas más de 1700, mejor mira opciones más modernas.

Resumen
La Sony a7 III es esa cámara que se niega a jubilarse. Con casi seis años a sus espaldas, sigue siendo una de las mejores full-frame para empezar en serio. Su combinación de enfoque automático ultrarrápido, una batería que parece no acabarse nunca y un precio que ahora ronda los 1100 dólares en ofertas la convierten en un chollo. No es la más nueva ni la que tiene más megapíxeles, pero para un fotógrafo híbrido o alguien que da el salto desde APS-C, es un caballo de batalla que lo da casi todo bien.
Preguntas frecuentes
Q: ¿La Sony a7 III sigue siendo buena opción en 2024?
Sin duda. Por menos de 1200 dólares usada o en oferta, tienes una full-frame con un enfoque top y una batería que deja en ridículo a muchas actuales. Si no necesitas 4K 60p sin recorte o 40 MP, es una compra genial.
Q: ¿Sirve para grabar vídeo profesional?
Sí, graba 4K 30p con muy buena calidad y perfiles de color para editar. Pero si necesitas 4K 60p sin recorte o 10 bits internos, mejor mira la Panasonic GH7 o las Sony más nuevas.
Q: ¿El visor electrónico es suficiente?
Tiene 2.36 millones de puntos, lo normal en su día. No es el más nítido ahora, pero se ve bien para encuadrar y revisar enfoque. Si vienes de una réflex básica, te parecerá bueno.
Para quién no es adecuado
Si tu prioridad es la fotografía de producto en estudio o necesitas recortes muy agresivos, los 24 MP se te van a quedar cortos. Tampoco es la cámara ideal si solo trabajas vídeo avanzado con 4K 60p constante. En esos casos, ve a por la Sony a7R V o la Panasonic GH7 directamente.
Veredicto
Si buscas tu primera full-frame o una segunda cámara todoterreno sin arruinarte, la Sony a7 III es una apuesta segurísima. Su batería y enfoque siguen en la élite, y el precio actual la pone en bandeja. No te va a fallar en una boda, un viaje o una sesión de retrato. Las hay más modernas, pero pocas tan equilibradas por este dinero.
