Information of Sony α7R IV full-frame camera (Body Only)
Overview
Ever more inspiring
Enter a whole new world of photographic expression with incomparable image quality and processing speed. A powerful new choice joins the α7R series with ever more advanced connectivity and enhanced reliability demanded by pros.
61.0MP full-frame back-illuminated CMOS sensor
The newly developed Exmor R CMOS image sensor boasts incomparable high resolution. The Back-illuminated design exhibits high sensitivity and low noise, despite an extremely high pixel count of 61.0MP
The latest image processing engine
The BIONZ X image processing engine and front-end LSI to maximise high-resolution sensor performance and up to 15-stops, of dynamic range.
Wide standard ISO 100-32000 range
Regardless of increased pixels, the α7R IV delivers highest standard ISO 32000, and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.
In-body 5-axis image stabilisation
The in-body 5-axis image stabiliser algorithm is optimised to maximise high-resolution 61.0-megapixel image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop higher shutter speed.
Shoot in absolute silence
Silent shooting not only provides a useful advantage in venues where quiet is required but avoids vibration that can cause camera-shake blur. A vibration-free shutter maximises the extremely high α7R IV resolution for crisp clear images.
Blur reducing structure
To maximise the incredible resolution available to the α7R IV the tiniest vibrations need to be supressed, so Sony re-engineered the shutter unit assembly with dampened screws to absorb any shutter shock. Combined with an enhanced image stabiliser algorithm, blur is dramatically reduced, and pin-sharp detail is reliably captured.
Shake-free remote shutter release
Remote camera operation using the optional wireless remote controller (RMT-P1BT) allows you to shoot effective stills while avoiding camera shake caused by pressing the shutter release. This maximises the image sensor’s high resolution.
5.76-million-dot UXGA OLED Tru-Finder
This 5.76-million-dot electronic viewfinder reproduces fine detail with approximately 1.6 times higher resolution than α7R III. You can select “High” quality mode for high-precision yet natural realism while suppressing moiré and jaggies for better concentration. Smoother image with 120/100fps frame rate makes it easy to track moving subjects.
The highest-level burst speed in its class
Regardless of remarkable image resolution, the α7R IV maintains its shooting speed of up to 10fps with a mechanical shutter (up to 8fps in live-view continuous shooting mode). This allows you to capture decisive moments — such as motion of wild animals — with subtle details made possible only by the 61.0MP high-resolution imaging capability.
Useful 26.2MP with APS-C cropping
Thanks to extraordinary image resolution, you can still maintain remarkable high-resolution images as approximately 26.2 megapixels even after cropping a full-frame image down into APS-C size. This means the α7R IV can help you proactively utilise 61.0-megapixel full-frame shooting, for example, in bird photography that tends to require cropping editing to magnify captured images.
Wide AF coverage
New image sensor supplies wide and high-density AF coverage with 567 phase-detection AF points (approx. 99.7% height and 74.0% width). 425-point contrast-detection AF supports precision focusing.
Fast AF despite higher resolution
Thanks to the enhanced Fast Hybrid AF, the α7R IV has the ability to capture a subject in remarkable detail, delivering swift AF even in dim lighting.
Steadfast AF tracking further improved
Increased AF points, widened coverage of AF sensor, and improved AF algorithm have further enhanced subject-tracking performance for consistent shooting, even of complex or sudden movements.
Now supports compositing 16 images with Pixel Shift Multi Shooting
This renewed feature shifts the sensor in half or one pixel increments in a programmed order to capture 16 pixel-shifted images, composited into one high-precision image of approx. 240.8MP from original data of approx. 963.2MP (equivalent). Still images of architecture and art, etc. are reproduced in true-to-life detail, texture, colour, mood, setting, and 3D-like realism, with breathtaking fidelity.
Steadfast AF tracking for stunning movies
Meet the rigorous autofocus demands of 4K movies with enhanced Fast Hybrid AF. You have high speed, precision, and tracking performance at your command for smooth, stable AF movie shooting. Adjust AF tracking sensitivity for steady focus.
Real-time Eye AF now for movie shooting
Real-time Eye AF newly supports movie shooting by detecting the subject’s eyes and continuing to track one eye. As the α7R IV keeps that eye in precise focus, you can concentrate on composition.
Touch Tracking for persistent focus on your subject
When shooting movies, touch a subject on the LCD monitor. The α7R IV begins focusing and following with Touch Tracking. If the α7R IV spots a human eye, Real-time Eye AF activates and tracks it, too.
Digital audio interface for clear sound recording
The Multi Interface Shoe (MI Shoe) is enhanced with a Digital audio interface. Use the new ECM-B1M Shotgun Microphone or new XLR Adaptor Kit to record high-quality sound with minimised deterioration.
