Sony opened the summer season in the best possible way: more than 6 months after the last expansion of its Alpha series by introducing the superb Sony Alpha a7 II, this series gets a new reinforcement - Sony Alpha a7R II!
The Sony Alpha a7R II, a successor of the astonishing Sony a7R, which was announced almost 2 years ago, arrives right on time for Sony and brings a marvelous 42.4MP full-frame Exmor R BSI CMOS sensor - the most advanced and versatile full-frame sensor that Sony has ever produced, let alone its resolution level! The optical low-pass filter (OLPF) is not present, which brings the ultimate level of clarity (ideal for scenery and landscape photography), while the anti-reflective (AR) coating of the sensor’s glass seal and gapless on-chip lens design radically improve light collection efficiency. Such a structure of the sensor brings high sensitivity, a low level of noise, a wide dynamic range, as well as an astounding ISO range of 100 to 25600 (expandable to 50-102400 for shooting stills). The high quality of images is also contributed to by an exceptional BIONZ X processor, which provides 5 fps continuous shooting rate.
The new MILC camera Sony a7R II pushes back frontiers when it comes to the video mode of the Alpha series as well. Namely, in its 'portfolio', the a7R II also offers 4K video (UHD) (3840 x 2160) at 30 fps, both in the full-frame mode and the Super 35mm crop mode, thanks to which video recording has obtained an entirely new dimension, and the a7R II has becomes a pioneer of 4K video in the full-frame format. In the full-frame mode, the a7R II makes use of the full width of its full-frame sensor for 4K recording, which enables users to utilize the expanded expressive power of the sensor to the max. On the other hand, in the Super 35mm crop mode, this interchangeable-lens camera collects a multitude of information from approximately 1.8x as many pixels as 4K by using full pixel readout without pixel binning, and oversamples the information to produce 4K movies with minimum moire and ‘jaggies’. Recording takes place in the XAVC S codec, at a bit rate of 100 Mbps during 4K recording and 50 Mbps during Full HD shooting.
As far as the focus is concerned, the Sony Alpha a7R II sports an absolutely staggering 399 phase-detection AF points, which operate in combination with 25 contrast AF points, and together achieve a result that is around 40% faster than the original Sony a7R. Furthermore, there is also a Silent Shooting mode by means of which images are captured quietly, without any vibration or movement on the sensor's part. Above all, the a7R II features 5-axis image stabilization, borrowed from the Sony Alpha a7 II, which neutralizes vibrations and brings additional stability to this mirrorless camera. This built-in stabilization cooperates perfectly with Sony α lenses and their Optical SteadyShot (OSS), bringing the maximum stability and crystal clear images.
When it comes to its compatibility to lenses, the MILC Sony a7R II perfectly combines with the growing line-up of Sony α-mount lenses (which totals 63 models so far, 12 of which are FE full-frame). These lenses are mounted on the a7R II by means of the LA-EA3 or LA-EA1 adapters and operate superbly with the said phase-detection AF system. Such a combination enables users to enjoy the wide AF coverage of this 399-point AF system, high-speed response, high tracking performance, with a wider range of lenses. This compatibility of the Sony Alpha a7R II with α lenses represents a unique case that the AF system of an interchangeable-lens camera can achieve impressive results with lenses originally aimed at DSLRs.
The scene can be framed through a tilting 3" 1,228,000-dot TFT LCD screen and an electronic 2,359,296-dot XGA OLED Tru-Finder with splendid 0.78x magnification. There is also built-in Wi-Fi with NFC, which enables easy connection with smart devices, and even easier transfer of images.
The Sony Alpha a7R II will arrive at the market in August, priced at $3200.
