Sony Alpha a99 II Specs and Performance

Sony Alpha a99 II Specs and Performance

Sony Alpha a99 II is an SLT camera which uses a semi-transparent mirror that splits light between the sensor and an AF module near the viewfinder.  Sony announced Sony Alpha a99 II on September 19th, 2016 to reinforce the company’s commitment to its SLR and SLT customers.  This camera is planned to be shipped in November. Sony Alpha a99 II is a professional camera, but unfortunately, the battery life is till miserable for a professional camera: 390 shots with the viewfinder and 490 shots via the LCD. With all these numbers, you will need the battery grip, which defeats the purpose of shrinking the camera body. Let’s see the full specification of each part of the camera as follow.

Sony Alpha a99 II Specifications

Sony Alpha a99 II has a Mid-size SLR body type. This camera has been launched with high-class specifications. This is a full-frame single lens translucent (SLT) camera. Sonny is adding its 4D Focus system to a full-frame camera for the first time in the a99 II. The Hybrid Phase Detect AF system uses 79 dedicated phase detect points with 399 focal plane phase detection points. These 79 ‘hybrid’ points help with fast autofocusing and the tracking of moving subjects. There is no need to flap up and down like in DSLR cameras since the mirror inside this camera is translucent. This enables you to have continuous autofocusing while using live view for both photos and videos, and it performs well in low-light situations in which other cameras would struggle.

Sony has also developed a new 5-axis in-body image stabilization system for its A-mount cameras that appears for the first time in Sony Alpha a99 II. the developed system compensates for 4.5 stps. If you half-pressing the shutter button, you will be able to preview the image stabilization in live view. Sony Alpha a99 II has the ability to detect light flicker and time its shutter to minimize the flicker’s effect on your photos when you are shooting indoor photos with artificial light.

Sony Alpha a99 II Performance

We need an opportunity of a full spin to know the performance of the camera more specifically, but early indications are promising enough. This camera image quality looks great – and crucially that AF performance, along with the high resolution frame rates, seem to work well. On the downside of Sony cameras related with their constant live view, they don’t tend to fare well for battery life. We can see at the comparison of less than 400 shots per charge – and only a single battery is supplied in the box.
