Unprecedented resolution and dynamic range combined with high-speed performance and a lightweight camera body

The Sony Alpha 7R IV features a newly developed 35mm full-frame, back-illuminated CMOS image sensor with a resolution of 61 MP. The new sensor’s back-illuminated structure and effective noiseNOISEThe appearance of random pixels scattered over a photo, similar to the grain effect seen in film photography, which degrades photo quality almost as if it is stained. It occurs when taking photos in low-light conditions, with very slow shutter speeds on high sensitivity (ISO) settings. It is caused by amplification done by the sensor when high ISO settings are used. You can counteract digital noise by lowering the sensitivity (ISO) setting of your camera - the lower the ISO setting, the lower the noise in the image. Typically cameras with larger sensors (like full-frame cameras) will inherently produce less noise due to larger pixels on the sensor. reduction techniques combine to deliver extremely low-noise and high-sensitivity performance, ensuring the absolute maximum image quality. The camera also boasts an impressive 15-stop dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights, and utilises algorithms from many of the latest Alpha cameras to maintain outstanding colour reproduction.


This full-frame model is equipped with an innovative 5-axis, optical in-body image stabilisation system that has been fine-tuned to support its high-resolution shooting capacity, resulting in a shutter speedSHUTTER SPEEDAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Shutter speed is the length of time that a single frame is exposed for, more specifically how fast the shutter opens and closes to permit light entering the lens, to reach the sensor. A slow shutter speed means a longer exposure time useful for motion blur like the silky look of flowing water, whereas a fast shutter speed means a shorter exposure time useful for freezing the appearance of motion in images like a hummingbird in flight. It is measured in seconds starting at 1 second and halving our doubling in time. For example: 1/2s, 1/4s and 1/8s are all fractions of a second with 1/2s being the longest exposure time, 1/4s half of that and 1/8s another half etc. advantage of 5.5-steps. Additionally, the shutter unit assembly has been carefully redesigned to reduce even the slightest movement that may cause blur.

The Alpha 7R IV also includes Sony’s highest resolution viewfinder ever, a 5.76 million dot UXGA OLED Tru-finder EVF. About 1.6x the resolution of the EVF in the Alpha 7R III, this new viewfinder provides an extremely accurate, true-to-life depiction of the scene being framed. The display quality can be set to ‘Standard’ or ‘High’ mode, and to either 60 fps or 120 fps refresh rate to best match the subject and shooting conditions.

Additionally, the new camera features an evolved PixelPIXELThe shortening of 'picture element', a basic unit of programmable colour forming the dots that make up an image. Pixel size depends on a camera’s resolution, which is measured in megapixels (MP), meaning millions of pixels. The more pixels on a sensor, the smaller they have to be to fit. An image's number (or density) of pixels correlate to the amount of information and image holds. Cameras with more pixels on the sensor have a higher pixel density and thus more resolving power, able to capture smaller details with much more clarity and accuracy. Higher resolution images can be cropped more agressively and also produce better quality large prints. Shift Multi Shooting mode that composites up to 16 full-resolution images. In this mode, the camera precisely shifts the sensor in one pixel or half-pixel increments to capture 16 separate pixel-shifted images containing a total of 963.2 million pixels of data, which are then composited into a 240.8 million pixel (19008 x 12672 pixels) image using Sony’s “Imaging Edge™” desktop application. Ideal for photographing architecture, art or any other still life subject, this enhanced mode produces photographs with a level of detail and colour accuracy that is simply stunning.


Features

  • World’s first 35mm full-frame 61.0 MP back-illuminated Exmor R™ CMOS image sensor with latest-generation BIONZ X™ image processor.
  • 15-stop dynamic range at low sensitivities, resulting in smooth, natural gradations ranging from deep shadows to highlights.
  • High-speed continuous shooting at up to 10 fps with full AF / AE tracking for approximately seven seconds in full-frame mode with an increased bufferBUFFERInternal camera memory used to cue images for saving to the memory card. This cueing is necessary due to the inherent writing speed limit of memory cards. When the buffer becomes full, it creates a bottleneck and the shooting rate reduces dramatically to compensate for the memory card speed limit. More professional cameras typically have much larger buffers which can cue a larger amount of images before the shooting rate is reduced. memory, and approximately three times as long in APS-C mode.
  • 567 focal-plane phase-detection AF points covering 74% of the image area and 425 contrastCONTRASTThe difference between areas of different brightness levels in a photograph: A high-contrast image has a greater difference between light and dark areas, whereas a low-contrast image has a narrow range of tones. Contrast is used to direct a viewer’s attention to a photographer’s subject either with colour contrast (bold versus duller colours) or tonal contrast (bright versus darker tones). AF points.
  • Debut of Real-time Eye AF for movie recording and advanced Real-time Tracking plus Real-time Eye AF for still image recording.
  • Features an APS-C crop mode delivering stunning high-resolution images of 26.2MP.
  • 5.76 million dot UXGA (Ultra-XGA) OLED Tru-Finder™ electronic viewfinder with outstanding detail, brightness and contrast.
  • Upgraded connectivity and operability including high-speed Wi-Fi support, wireless PC remote connectivity, FTP wireless transfer, faster data transfer via USB and more.
  • Professional 4K movie recording functionality including full pixel readout with no pixel binning in Super 35mm mode, S-Log3, HDR workflow support.
  • Multi-Interface Shoe™ with digital audio interface delivers high-quality sound recording with Sony’s new microphone and XLR microphone adaptor.
