DxOmark (Click here) tested the new Sony A7sII. Unsurprisingly the performance of the new camera matches the previous model. But there are small changes and the A7sII has a negligible 2 points lower score:
Although the DxOMark score is slightly below the earlier A7S, the difference is pretty much negligible. The A7S II is slightly behind in color sensitivity, equating to just 0.3 bits color depth, which isn’t really perceivable in use. As for dynamic range, the new model is practically identical to its predecessor — and not just at base, but more or less throughout the ISO range. However there has been an improvement or refinement perhaps, between ISO3200 and 12800
Conclusion
Like its predecessor, the sensor in A7S II has impressive low-light performance — in fact, very impressive high ISO dynamic range, particularly between ISO3200 and 12800. But it comes at the expense of pixel count and the dynamics are not much of an improvement over the A7S, which (along with the $2999 price tag) we suspect will continue to limit the appeal to still photographers. As a camera intended primarily for videographers, however, that may not be much of an issue. Anyone that has invested in the A7 or A7R variants looking for a complementary video-centric model need look no further than the A7S II.
Of course what makes the A7sII standout compared to the predecessor is the 4K internal recording and the 5 axis stabilization. It’s a camera mainly made for film makers.
