Sony a7R II Review

Pinterest LinkedIn Tumblr

Sony has had ambitious plans for the camera market ever since it bought Konica Minolta’s camera business in 2006. But after some initial excitement, there were only sporadic periods of activity, and the attention of many photographers and industry observers waned somewhat.

Then in September 2013, the company launched the RX1, an impressively small compact camera. A little over a year later the Alpha 7 and 7R were unveiled, and we really started paying attention. These were the world’s first compact system cameras to feature a full-frame sensor, and their little size drew an audible gasp at the UK press announcement.

While the Alpha 7 had 24 million pixels and was designed to be a ‘fast’ all-rounder, the Alpha 7R boasted 36 million pixels and was intended to be attractive to landscape and still life photographers looking to capture masses of detail.

The latest addition to the range is the Alpha 7R II, the highest-resolution model yet, trumping the A7R’s 36 million pixels with an effective pixel count of 42.4 million. This is coupled with Sony’s Bionz X processor, which enables a native sensitivity range of ISO 100-25,600, with expansion settings taking the range to ISO 50-102,400. It’s also possible to shoot at up to 5fps (frames per second) with functioning continuous autofocus (AF).

To push detail resolution even further, the sensor has no optical low pass filter (OLPF). And to enable the photosites (pixels) to be made bigger than they would otherwise be, the A7R II is the first camera to feature a full-frame backside-illuminated (BSI) sensor.

Sony has also used copper wiring instead of aluminium on the sensor, and this helps to increase the sensor’s readout speed by 3.5x over the original A7R’s. In addition to boosting image transfer times, this should help improve autofocus velocity and help combat rolling shutter effect in video mode, as the information is relayed quicker. Whereas the original Alpha 7R has a contrast-detection autofocus (AF) system with 25 points, the A7R II includes a hybrid AF program that combines both contrast and phase-recognition focusing. This has a total of 399 factors covering 45% of the imaging area.

Sony claims the The7R II’s new sensor design enables the autofocusing system to be 40% faster than the previous camera’s, while new algorithms enable better motion tracking. With this in mind, the new camera has a wider range of focusing modes compared to the original model.

These include Flexible Spot and Lock-on AF (Wide/Zone/Centre/Flexible Place – with small, middle and large options as well as Expand Flexible Spot) to follow moving subjects. The camera uses data about object distance from all of the AF points to ascertain the location of the subject, whether it’s moving in relation to the background, and the positioning of other objects in the scene.

In another first for a full-frame camera, the A7R II has in-body 5-axis image stabilisation, which helps reduce image blur in stills and jitters in video footage. Sony has upgraded the 0.5-inch 2,359,296-dot electronic viewfinder to an OLED, and there’s also a new shutter unit that’s designed to create less vibration and which has a 500,000-cycle life.

Although Sony says the A7S is the best option for shooting video with a full-frame compact system camera, the A7R II is the first full-frame CSC to offer 4K recording in-camera; the A7S requires an external recorder.

There are two options for recording 4K footage with the A7R II; the best quality is produced when the camera is set to Super 35mm, as there’s no line skipping or pixel binning. The downside to using this mode is that the video frame is narrower than when shooting stills. Alternatively, Super 35mm mode can be turned off so that the camera uses the whole imaging area – presumably with pixel binning.

Other video-related improvements over the A7R include the ability to use Picture Profiles and set specific values for Black Level, Gamma and Knee (highlight compression), plus colour adjustment (Colour Mode, Colour Degree, Colour Phase and Color Depth) and Detail.

The Gamma settings include Sony’s S-Log2 setting, which is claimed to increase the dynamic range to up to 1300% to retain highlight and shadow detail, and generate footage that looks very flat straight from the camera but that is ideal for post-capture grading.

Movies could be shot in XAVC S format with MPEG-4 AVC/H.264 compression, or AVCHD with MPEG-4 AVC/H.264 or MP4: MPEG-4 AVC/H.264 compression. In NTSC the maximum quality option will be XAVC S format at 4K and 30p/100Mbps while in PAL it’s XAVC S 4K at 25p/100Mbps. As usual Full HD shooting is possible, with frame rates around 60p at 50Mbps (NTSC) or 50p at 50Mbps (PAL). There’s also Time code to help with scene identification and syncing footage from multiple cameras.
