As a result, the A99 II displays a notable improvement in its low-light performance compared to the original A99, achieving a higher low-light ISO score of 2317 ISO. The A99 II’s headline Landscape and Portrait scores haven’t progressed, but it still offers very solid results at base ISO and improved performance in the medium-to-high ISO sensitivities for color and dynamic range, thanks to that BSI sensor. This makes the Sony SLT A99 II a great choice for photographers after a high-resolution camera with good low-light performance.
