Reaching the peak of resolution: 61.0MP12 full-frame CMOS sensor

Reaching the peak of resolution: 61.0MP12 full-frame CMOS sensor

Sony’s newly developed 35mm full-frame back-illuminated CMOS sensor with 61.0 megapixels12 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.  Wide 15-stop dynamic range 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 61.0MP12 resolution

Features maximising superb 61.0MP12 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-stop 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.

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; 120/100fps 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

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-319. 567-point phase-detection AF and 425-point contrast-detection AF provide wider image area coverage 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.

14-bit RAW output for natural gradations

14-bit RAW output for natural gradations

he 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 RAW output available even when shooting in silent or continuous mode.
