SONY Alpha A7R Mark IV

ILCE-7RM4


The Sony A7R Mark IV’s 61-million-pixel 35mm sensor is a world first, which the company says delivers ‘medium format quality’ in its announcement livestream.

The sensor is a new generation and back-side illuminated, and it provides 15 stops of dynamic range. As well as 61-megapixel images, the Sony A7R Mark IV can also produce images with 26 million pixels in APS-C crop mode.

What’s more, its revampled Pixel Shift Multi-Shooting mode can produce images at 240-megapixel resolution. It does this by capturing 960 megapixels worth of data from 16 images, which it then composites together using Sony’s Imaging Edge software.

The A7R Mark IV boasts 567 phase detection AF points in full-frame mode, which cover 74% of the frame. In the camera’s APS-C mode it has 325 AF points which then cover nearly the entire frame.

Sony says the A7 IV is also built for speed. It can capture full-resolution 61-megapixel images in continuous shooting mode, and up to 68 images per continuous burst.

Sony says the A7R Mark IV also includes its AI-driven Real-time Eye AF and Real-time Tracking modes.

Also among its key features is 5.5-stop, 5-axis in-body image stabilisation, wireless tethering capability, faster USB connection, 802.11ac Wi-Fi plus Bluetooth and studio lighting support.


Sony A7R Mark IV Video Specs

The Sony A7R Mark IV can record 4K video using the full width of the sensor for capture. Also, for the first time, Sony has included real-time Eye AF for movies – the first time for video capture.

Other Sony A7R IV video specs include S-Log3 mode for capturing wide 14-stop dynamic range and Hybrid Log-Gamma mode.

As for audio, Sony has included a new digital audio interface between the microphone and camera. A conventional microphone sends an analogue signal that the camera converts to a digital format. But Sony’s new digital microphone, the ECM-B1M, transfers the audio signal from the microphone through the A7 Mark IV’s Multi-Interface Shoe to record digitally directly to the codec.


Sony A7R Mark IV body design

On board the Sony A7R Mark IV body are dual UHS-II card slots and a refined focus control to help boost productivity. There’s also a 5.76-million-dot UXGA OLED Tru-finder.

Sony says it has improved the A7 Mark IV’s grip and also provided enhanced dust and moisture resistance, as well as a sealed chassis.

FEATURES


Reaching the peak of resolution: 61.0MP13 full-frame CMOS sensor

Sony’s newly developed 35mm full-frame back-illuminated CMOS sensor with 61.0 megapixels13 enables the full-frame mirrorless α7R IV to attain expressive prowess once expected only in conventional medium-format cameras. Thanks to this mirrorless design, absence of mechanical mirror shock can maximise resolution without negative effect on image quality. The α7R IV realises the level of image quality that surpasses the expectation for conventional full-frame cameras especially in the low- to mid-sensitivity range. Sony’s proprietary technology achieves superb high resolution while assuring low noise and high sensitivity.

Enhanced image processing engine makes the most of CMOS sensor

To match the excellence of the new image sensor, high-speed BIONZ X image processing engine is also further enhanced to faithfully reproduce details and reduce noise significantly. Noise that tends to occur due to heightened pixel count is minimised for high image quality, especially in the standard ISO sensitivity range up to ISO 32000. 14 Wide 15-stop dynamic range15 at low ISO sensitivity (for stills) delivers smoother reproduction of gradations from shadow to highlight. Moreover, the α7R IV’s inherited colour reproduction in still pictures — acclaimed in the latest α series — captures skin colour in portraits and vivid colour of flowers for natural α7R IV depiction.

Features maximising superb 61.0MP13 resolution

The α7R IV’s extremely high image 61.0-megapixel resolution performance is maximised by other α7R IV advantages, one of which is 5-axis optical in-body image stabilisation with optimised algorithms to achieve up to a 5.5-stop16 shutter speed advantage. Another outstanding feature is the electronic shutter allowing silent, vibration-free shooting. Additionally, the α7R IV incorporates an internal damper structure to absorb the impact of shutter motion for a minimum of shutter vibration. Many features in the α7R IV serve for realising sharply resolved imaging.

14-bit RAW output for natural gradations

The α7R IV supports compressed and uncompressed 14-bit RAW output for smoother, more natural gradations that contribute to higher overall image quality. Taking advantage of even higher 16-bit processing in the imaging engine, front-end LSI and the enhanced BIONZ X image processor make 14-bit RAW17 output available even when shooting in silent or continuous mode18.

5.76-million-dot UXGA OLED Tru-Finder

Newly featured in the α7R IV, this 5.76-million-dot electronic viewfinder provides high-precision, high-brightness, and high-contrast visibility, reproducing fine detail with 1.6 times higher resolution than α7R III. “High Display Quality” mode draws on the effective 61.0MP (approx.) image sensor to suppress moiré and jaggies for highly precise and natural images on viewfinder; 120/100fps19 of “High” finder frame rate mode shows smoother motion, so it’s simpler to trace moving subjects. Fluorine coating makes it easier to remove dirt or a fingerprint from the lens, for more comfortable viewing in inclement weather and better concentration on shooting.

Wide, fast, and steadfast AF evolution

Thanks to increased coverage and density of AF points and enhanced algorithm for tracking moving subjects, overall AF performance has evolved to provide steadfast, accurate tracking of complex subject motion and speed changes. The α7R IV’s Fast Hybrid AF system combines high-speed, highly trackable phase-detection and high-precision contrast-detection autofocusing, even for shooting venues as dimly lit as EV-320. 567-point phase-detection AF and 425-point contrast-detection AF provide wider image area coverage21 of 99.7% height and 74.0% width. In addition, this remarkable AF system provides as rapid response as α7R III, despite mass data handling due to the extremely high-resolution CMOS sensor, even in dim shooting venues.

Exceptional high-speed 10fps burst shooting with AF/AE tracking

Despite high resolution of 61.0MP13, an ingenious algorithm enables efficient processing for high-speed continuous shooting of up to 10fps22 with AF/AE tracking through a mechanical shutter. It is also possible to shoot continuously at up to 8fps in live-view mode, with minimal display time lag for capturing fast-moving subjects. After a full-frame image is cropped down to APS-C size or if APS-C shooting mode is chosen, you can still get 26.2MP high-resolution images. This is a great advantage for wild animal photographers who rely on cropping after capturing images of quickly moving animals/birds afar.

Up to 68 images in continuous shooting

Professional photographers need to achieve consistent shooting without interruption. With 1.5x greater buffer memory, system speed, and UHS-II support, the α7R IV can capture up to approx. 68 images23 in a continuous burst at 10fps24. With APS-C shooting mode, approximately three times more photos can be shot than with full-frame shooting mode. Fn menu/menu display access, setting changes, and review playback can occur during data writing. A countdown of the number of still images remaining to be written to memory is on display during playback.

Anti-flicker shooting25

Flicker from fluorescent and other artificial lighting is automatically detected and shutter action is timed to minimise the effect of flicker on still images. This suppresses exposure and colour anomalies at the top and bottom of images shot at high shutter speeds, as well as exposure and colour inconsistency between continuous shots, so you can take images indoors with more confidence.

Dual media slots, both supporting UHS-II

The α7R IV provides two media slots for SD cards, both SLOT 1 and SLOT 2 now compatible with UHS-I and UHS-II for fast mass-volume data writing. Two cards in the slots can be used to simultaneously record or relay record data; separate RAW data from JPEG data, or stills from movies; and copy data from one card to the other. A slide lock structure prevents the memory card cover from being opened unintentionally.

Shooting for more professional lengths

The α7R IV employs the large-capacity NP-FZ100 battery just like α7R III. Due to more energy-efficient circuit design, the α7R IV matches α7R III usage level longevity, despite higher resolution of the α7R IV image sensor and EVF. An optional Vertical Grip (VG-C4EM) can hold two batteries, and an optional Multi Battery Adaptor Kit (NPA-MQZ1K) can hold up to four batteries for even longer hours of shooting. In addition to the use of such optional accessories, USB Type-C® and Multi/Micro USB ports allow external mobile batteries to power the camera for further extended recording.

Enhanced Real-time Eye AF (human eye) delivers more successful portraiture

Real-time Eye AF works in tandem with Real-time Tracking technology, based on the latest evolutionary advances in artificial intelligence, for highly efficient portrait shooting. This progressive system detects and processes face and eye data in real time, and stays locked onto the eye of the subject with unprecedented precision. When “Face/Eye Priority in AF” is ON, Eye AF (AF-C/AF-S/AF-A mode) can be activated not only through a custom key assignment, but also by half-pressing the shutter button or pressing the AF-ON button. This function now allows you to choose a particular eye — left or right, in advance or during shooting. Real-time Eye AF supports movie shooting in addition to stills.

Real-time Eye AF for Animals reliably tracks wild animals and pets26

Advanced AI-based subject recognition in Sony’s Real-time Eye AF includes a new algorithm supporting animal tracking for fast, precise, automatic detection and tracking of an animal’s eye. This new capability will greatly increase your success rate when shooting pictures of animals in the wild or beloved pets at home, situations where accurate focus has been a challenge.27 All AF-C, AF-S, and AF-A focus modes are supported.

Real-time Tracking keeps focusing on tracked subjects

With this technology, accurate focus is maintained automatically while the shutter button is half-pressed. You can select a subject as you intend, rely on the α7R IV, and concentrate on your composition since the camera takes care of subject tracking. A newly adopted Real-time Tracking algorithm uses colour, pattern (brightness), and subject distance (depth) data to process spatial information while AI technology detects subject’s face and eye in real time. Available for both stills and movies.


Focal-plane phase-detection AF supports A-mount lenses28

Phase-detection AF can operate even when an A-mount lens is attached to the α7R IV via an LA-EA3 Mount Adaptor. The 567-point focal-plane phase-detection AF system provides wide-area coverage, fast response, and high-performance tracking even if an A-mount lens is attached.

Wireless PC Remote function

Using the α7R IV alone, you can operate newly supported wireless PC Remote functions via Wi-Fi (2.4GHz/5GHz selectable29) to remotely control camera settings or send captured images to the camera while shooting. This cable-free setting allows maximum shooting freedom in indoor and outdoor shooting sessions. Moreover, the α7R IV also provides PC Remote functions via SuperSpeed USB 5Gbps (USB 3.2) compatible USB Type-C™ port, for image data transfer at time of tether-priority shooting. Even large-sized RAW images can be transferred smoothly and checked via PC immediately.

Image of the camera's standard sync terminal for synchronisation with external flash units


Versatile flash compatibility

The α7R IV has a sync terminal, so non-dedicated flash units and cables with standard sync terminals can be connected for convenient synchronisation with studio flash units, etc. Release time lag when shooting with flash is minimised for smooth, responsive flash photography. Continuous flash shooting at up to 10fps offers advanced capture capability.30 To enhance versatility further, slow sync and rear curtain sync can be selected when shooting with wireless off-camera flash.31

Pixel Shift Multi Shooting32 newly supports compositing a picture from 16 pixel-shifted images

A different dimension of resolution opens with Pixel Shift Multi Shooting. The α7R IV now supports image compositing from 16 pixel-shifted images in addition to previously available compositing from four images. Applying advanced image stabilisation control, this renewed feature precisely shifts the sensor in half-pixel increments four times and in one-pixel increments four times alternately, to capture a total of 16 pixel-shifted images. These are composited by PC32 into one high-precision image of approx. 240.8 million pixels (19,008 x 12,672) from original data that holds the equivalent of approx. 963.2 million pixels to achieve overwhelming resolution in a single picture.33 Still images of architecture and art are captured in true-to-life detail, texture, colour, mood, setting, and 3D-like realism, recreating hues with minimal moiré or colour artifacts, and even reproducing atmosphere and surroundings with breathtaking fidelity for unprecedented accuracy in real-life imagination.

Redesigned controls for confident and comfortable operation

A new multi-selector lets you shift point of focus quickly and intuitively to avoid missing moving subjects. The surface texture is changed to enhance button response for easier and more confident operation, in reply to pro users’ requests. In addition, the AF-ON button is enlarged and optimised for easier access, with an adjusted click feeling and location. And, the new Exposure Compensation Dial Lock Button locks or unlocks alternately at each press, and prevents accidental turning when set to lock position. These improvements enhance your concentration on shutter release to “capture the moment” instantly.
