DXO completed testing the Sony a99 Mark II and as expected the translucent mirror affected it’s ability to perform against the Sony a7R Mark II in image quality. The camera still outperforms the a7R Mark II in AF most of the time, but that has always been the trade off of translucent mirror technology and is why it fell out of favor with most photographers.
The Sony SLT A99 II gives landscape, architectural, advertising or magazine photographers desiring plenty of pixels for large-scale or high-quality prints another camera to consider. Although its $3198 price tag puts it squarely in the professional or very serious enthusiast category, it’s no more expensive than the 42Mp, $3198 Sony A7R II, and actually cheaper than the 50Mp, $3699 Canon 5DS. The switch to a 42Mp BSI sensor delivers some excellent image quality, with great results both at base ISO and towards the middle of the sensitivity range. Although better color depth and dynamic range image quality at base ISO is available on the Sony A7R II, photographers after a larger DSLR style body might prefer the A99 II’s design and handling over the mirrorless A7R II, and its overall image quality isn’t far behind. What’s more, the A99 II’s fast 12fps burst shooting with autofocus tracking puts it on par with high-end professional sports cameras, and its BSI sensor technology ensures good low-light performance despite its massive 42Mp resolution. The SLT fixed translucent mirror and resulting EVF might be a drawback for some photographers used to an optical viewfinder, but this brings other advantages for some subjects and in some situations.
With such additional features as a hybrid autofocus system, a 5-axis sensor shift image stabilization, a BIONZ X image processor, as well as internal UHD 4K-video and HD capture at 120fps for slow motion effects, the Sony SLT A99 II offers good all-round specifications. Add to that its 42Mp resolution with exceptional image quality and you get an awful lot of camera for your mone,y making the Sony SLT A99 II a serious contender for high-resolution shooting.
