- Alpha a7R IV Mirrorless Camera (V2) -Thanks to an evolutionary leap in image processing power and efficiency, the Alpha 7R IV combines world's first high-resolution 61MP back-illuminated Exmor R CMOS image sensor with impressive shooting speeds at up to 10 fps with full AF/AE tracking, as well as beautiful 4K HDR video, wide 15-stop dynamic range and high sensitivity with area specific noise reduction.World's first 61MP pixels full-frame sensorThe Alpha 7R IV features the world's first 35mm full-frame back-illuminated CMOS image sensor with 61MP effective pixels, delivering depth and dimension that was once only available in medium-format cameras. The back-illuminated structure and effective area specific noise reduction techniques combine to deliver an extraordinary blend of low noise and high sensitivity for enormous imaging potential.15-stop dynamic rangeThe Alpha 7R IV boasts an impressive 15-stop dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights, and utilizes algorithms from many of the latest Alpha cameras to maintain outstanding color reproduction.BIONZ X processing maximizes sensor potentialAdvanced Detail Reproduction Technology and Area-specific Noise Reduction - both features of Sony's BIONZ X image processing engine - have been carefully tuned to maximize the performance of a sensor that offers approximately 1.5 times more resolution than the highly acclaimed Alpha 7R III, achieving extremely fine, realistic reproduction of textures and details.Low noise at High ISOA standard ISO range that extends from ISO 100 up to ISO 32000 with undiminished quality is expandable to ISO 50 to ISO 102400 for still images, make it possible to achieve optimum image quality in just about any light. Noise is effectively minimized even at high sensitivities, maintaining excellent image quality even with this sensor's high pixel count.16-bit processing and 14-bit RAW outputImage sensor output is processed in 16-bit form by the front-end LSI and BIONZ X image processing engine before being output as compressed or uncompressed 14-bit RAW files that have smoother, more natural gradations for higher overall image quality. 14-bit RAW output is available even when shooting in silent or continuous mode.Serious speed up to 10fps with AF/AE trackingAn advanced mechanical shutter unit and updated image processing algorithms allow the innovative new full-frame Alpha 7R IV to shoot full 61MP resolution images at up to 10 fps with continuous and accurate autofocus and auto exposure (AF/AE) tracking for up to approximately seven seconds in JPEG and RAW, and approx. three times as long in 26.2MPii APS-C crop mode. These high-speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail.4D FOCUS - Wide, fast, reliable AF gets the shotThe new image sensor in the Alpha 7R IV features 567 phase detection points in a high-density focal plane phase-detection AF system, covering approximately 99.7% of the image area vertically and 74.0% horizontally. High-density focal plane phase-detection works with 425 contrast AF points in a Fast Hybrid AF system that can handle a huge volume of data at high speed, snapping rapidly into focus with just about any subject and situation.
