Sony's Pixel Shift Multi Shooting is also present, which shoots 16 high-resolution images, with a slight shift in sensor positioning for each image, either by one or half a pixel.

Sony's well-regarded Eye AF is on board, ideal for events and wedding shooters, forming part of the autofocus system with 567 focal-plane phase-detection AF points, which provides 74% coverage - a significant increment on the A7R III. You can find out more at Sony.

The high-res sensor, which is said to capture 15 stops of dynamic range, is complemented by a new 5.76-million-dot UXGA OLED viewinder that Sony said is - you guessed it - its highest-resolution electronic viewfinder (EVF) ever.

The camera captures 4K UHD (3840 x 2160) XAVC S video at up to 30p across the full width of the CMOS sensor, and offers full-pixel readout (without pixel-binning) when shooting in Super 35mm mode.

The A7R IV also debuts real-time Eye AF when shooting movies and also supports Eye AF for humans and animals. Sony also announced the ECM-B1M shotgun microphone, XLR-K3M XLR adopter kit, which go on sale in September and October for $350 (around Rs. 24,000) and $600 (roughly Rs. 41,200), respectively. The A7R IV looks set to be one of the best mirrorless cameras on the market, if not THE best. The big camera brands were effectively put on notice when Sony started dabbling with full-frame sensors, and since then, the company that started the Walkman has made the mirrorless camera a more than formidable beast to take on the likes of Canon and Nikon, so much that they've had to respond with their own mirrorless models.

Sony is also proudly touting the fact that the A7R IV can achieve continuous, accurate AF/AE tracking for up to 7 seconds in full-frame, full-resolution mode, also aided by the 425 contrast-detection points.

Sony has also revealed that Real Time tracking will be available for still images and, for the first time, videos (up to 4K).

Wireless data transfer and tethering is available on 2.4gHz and 5gHz Wi-Fi bands, with the camera also supporting USB-C. Everything videographers need, in short.

Despite its increased pixel count compared to the Alpha 7R III, the battery life has been improved with a CIPA measurement of up to 670 still images per change using LCD monitor, or 530 images with EVF.

"The new Alpha 7R IV combines medium format-level image quality with high-speed shooting, extremely fast focusing and an extensive list of upgrades to design, connectivity and usability", said Neal Manowitz, deputy president of Sony Electronics Imaging Product and Solutions Americas, in a prepared statement.

Sony has also beefed up the handgrip, making for a more secure hold.

There's two UHS-II compatible media slots, and camera settings can be saved to, and read from an inserted memory card.

The Sony A7R IV will ship in Europe this August, at a price around €4,000.
