SONY aR7IV
* Full-frame 61MP BSI-CMOS sensor
* 15 stops of dynamic range
* Hybrid AF system with 567 PDAF and 425 contrast-detect point, and 74% frame coverage
* Real-time eye, human and animal AF
* 10 fps with continuous AF for up to 68 photos
* Redesigned, with upgraded weather-sealing, including foam gaskets around the battery and card doors, and raised lips around all the connectors that, along with rubber port doors prevent water from working its way around the seal
* Significantly deeper grip, a larger joystick and repositioned, 'newly designed' buttons and dials
* 5.76M-dot EVF
* Dual UHS-II card slots and USB-C
* 802.11ac Wi-Fi plus Bluetooth and NFC
* NP-FZ100 battery, which can take approximately 670 shots using the LCD and 530 using the EVF, based on CIPA standard testing. A battery grip, which holds two FZ100s, is priced at $400.
* Built-in 5-axis image stabilization, which can reduce shake by up to 5.5 stops
* Bionz X processor (same as the Mark III)
* Tilting 1.44M-dot touchscreen display (same as the Mark III)
* 26MP APS-C crop mode with near-total-frame AF coverage and 325 PDAF points.
* Pixel Shift mode can captures 960 Megapixels worth of data by compositing 16 images, which can be processed via Sony's Imaging Edge software to create 240MP photos
* Users have a choice of 16-shot mode that makes 1/2 pixel shifts or a 4-shot mode that makes full pixel shifts. Using the 1/2 shift mode you get twice the spatial resolution and full color at each pixel, while the full shift mode (which uses 4 images) just cancels out the Bayer filter.
* Oversampled 4K/30p video capture with touch tracking and real-time Eye AF, and support for 8-bit S-Log2/3 and HLG
* Super 35 crop with additional 1.2x crop at 30p and 1.1x at 24p
* Top bit rate is 100Mbps using XAVC S (same as the Mark III)
* New digital interface between the the microphone and camera, making the a7R IV the first camera to accept digital audio input
* New microphone and an XLR adapter, both of which have built-in ADCs to provide digital signal to the camera (but which also have analog output modes to retain compatibility with older cameras)
* New connectivity options, thanks to the addition of 5GHz Wi-Fi (Wi-Fi can now be used for tethered shooting as well)
