Sony has again surpassed its rival with the launch of SonyA7R IV full-frame mirrorless camera. The camera is packed with a 61-megapixel backside-illuminated sensor with 15 stops of dynamic range, delivering you the highest resolution yet for a full-frame camera. You can also capture images of up to 240 megapixels using pixel-shift mode. You will not need to capture enormous RAW files as it delivers 26.2-megapixel photos in APS-C crop mode.
Moving on the ISO which ranges from 100 to 32,000, or 50 to 102,400 in expanded mode. In spite of the extremely high resolution, the A7R IV can capture images at 10 fps in continuous AF tracking mode, and up to 68 images in a burst. These specs and features are highly impressive, considering the potential size of the images. Moreover, it has 567 full-frame phase-detection AF points 325 in crop sensor mode, and 425 contrast AF points.
The sensors allow 100 percent autofocus coverage, it would allow for accurate focus even at the edges of the frame. And naturally features real-time Eye AF both for humans and pets thanks to the advanced latest-generation BIONZ X image processor. Sony has redesigned the body with a larger, deeper grip, fixing one of the most complained-about issues on the A7R III. It has a five-axis image stabilizer that should be handy for both movies and stills, along with an all-new 5.76 million dot OLED electronic viewfinder the highest resolution yet on a Sony camera.
The rear display is fully touch-enabled but unfortunately doesn’t spin around 180 degrees for vloggers. For video, the camera can handle 4K at 30 fps (1080p at 120 fps), with S-Log 2/3 capability, HDR recording and no pixel binning in Super 35mm mode. The A7R IV supports real-time Eye AF in movie mode which makes it the first Sony camera with this capability. You can also get touch tracking functionality which lets you change focus from one subject to another by selecting them on display.
You can capture 4K using the full width of the sensor, but like the A7R III, it does so with significant pixel binning. However, it does not support 10-bit 4K recording either internally or through the HDMI output, so it’s behind other models from Fujifilm, Panasonic, and Nikon in that regard. The omission is a sign that sony is still protecting its professional video camera market. The Sony A7R IV has an all-new Multi-Interface Shoe, allowing a digital connection from the $350 ECM-B1M shotgun microphone or $600 XLR-K3M XLR adaptor kit.
You can not only adjust levels directly to the mic but also change the relative directionality on the new mic, thanks to the eight mic capsules and an advanced digital signal processor. Other features include faster data transfer via USB-C 3.2 Gen 1 and WiFi, dual UHS-II SD card slots, an upgraded grip, and dust & moisture resistance.
