DxOMark released their test results for the Sony a7 II camera:
Improvements to build quality and handling alongside the addition of a new sensor shift image stabilisation system make the new Sony A7II an even more appealing prospect to both serious amateur and professional photographers. Packing essentially the same 24.2Mp full frame sensor there’s no discernable improvement in image quality over its predecessor the Sony A7, but it still remains one of the best scoring sensors on our database ranking in 11th place overall. With alternative 12.2Mp and 36.4Mp variants available in the A7 range the A7II plots a steady course between its two counterparts and offers a good balance between resolution and image quality. If it’s the very best image quality you desire for studio or landscape work and can cope with the limitations of shooting at the lowest ISO sensitivities the 36.4Mp Sony A7R offers better results for both Colour and Dynamic Range. If however you’re after a hybrid that excels in low light the lower resolution 12.2Mp Sony A7S with its greater pixel pitch and maximum sensitivity of ISO 409,600 is the one to go for. We will have to wait and see if the other manufacturers release an alternative full frame hybrid camera to rival Sony’s A7 series in 2015, but for now it remains a unique proposition in the market.
