Sony introducerer Alpha 77 og Alpha 65 med 24,3 megapixel

Sonys portefølje af digitalkameraer med Translucent Mirror-teknologi udvides nu med to nye A-mount-kameraer, som appellerer til både avancerede amatører og mere professionelle fotoentusiaster.

 

Med lanceringen af SLT-A77 (α77) og SLT-A65 (α65) raffinerer Sony Translucent Mirror-teknologien yderligere og præsenterer de hurtigste kameraer på markedet med udskiftelige objektiver inden for dette segment. Også ergonomien er forbedret med et nyt greb. En mere intuitiv placering af betjeningsknapperne gør det let at kende forskellen mellem de forskellige betjeningsknapper, så man blot behøver at fokusere på sit motiv via den elektroniske søger XGA OLED Tru-Finder

 

Både hvad angår performance og konstruktion er α77 en værdig efterfølger til det anmelderroste DSLR-kamera α700.
