Introducing the Sony A7R II, a 42.4MP mirrorless camera with an image stabilised full-frame BSI CMOS sensor. Unlike its predecessor, the camera includes on-sensor phase detection elements for faster autofocus, which with the correct adapter, continues to work with other brands’ lenses. The camera also has a revised shutter mechanism, rated to 500,000 actuations but also promising less vibration than the one on its predecessor. The sensor is by far the largest backside illuminated CMOS chip to be released, allowing the maximum expanded ISO to rise two stops to 102,400.
The Sony A7R II also gains 5-axis image stabilisation that is rated at 4.5 stops, according to CIPA standard. The camera can capture 4K (UHD) video at 30p/25p or 24p in the XAVC S 4K format. The 4K video can be taken either from the full sensor width or from a Super 35 crop. Even this smaller crop over-samples by around 1.4x.
The new A7R II is the world’s first back-illuminated full-frame Exmor R CMOS sensor, which realises high resolution (42.4 MP approx. effective megapixels), high sensitivity (expandable up to ISO 102400) and high speed AF response up to 40% faster than the original A7R thanks to it’s 399 focal plane phase detection AF points.
The newly developed 42.4 MP back-illuminated CMOS sensor is the most advanced, versatile and highest resolution full-frame image sensor that Sony has created, this allows the α7R II to reach new levels of quality, sensitivity and response speed. In the past, many photographers have been forced to choose between high-resolution and high-speed or high resolution and high sensitivity when selecting a camera. The A7R II eliminates that sacrifice thanks to its innovative image sensor.
You can lock onto your subjects quickly and without hesitation thanks to the revamped Fast Hybrid AF packed into the a7RII. It uses 399 on-sensor phase-detect AF points with 45% coverage along with 25 contrast-detect AF points in order to improve the speed, accuracy and tracking performance of the system. Faster readout thanks to the back-illuminated sensor structure also allows for tracking while shooting at the top continuous shooting rate of 5 fps. This can be captured in a burst of up to 24 frames when shooting in JPEG Fine L format at 42 MP and a continuous AF Display allows users to view the active AF points.
Another feature available with this AF system is a Lock-on AF tracking that will analyze more information from the scene to provide dramatically improved accuracy and stability. Eye AF is also available which will prioritise a subject’s pupil for excellent portraits even with a shallow depth of field.
For the Videographer, the A7RII features a 3.5mm microphone input jack for compatibility with external microphones. And for users needing more the a7RII is also compatible with the Sony XLR-K2M XLR Adapter for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs. For monitoring audio the a7RII features a 3.5mm headphone jack as well as real time audio levels for a visual reference.
