Sony Intros Full-Frame Mirrorless Alpha 7R IV Camera
Sony Electronics has unveiled the Alpha 7R IV full-frame mirrorless camera endowed with what it says is the world’s first 61-megapixel, back-illuminated, CMOS full-frame image sensor. The model will be available in September at a suggested retail price of $3,500.
Sony announced the camera at a New York City-held press event Tuesday, where it cited a No. 1 global share for 2018 and 2019 in both the mirrorless and the full-frame camera market segments. In fact, said Sony Electronics president and COO Mike Fasulo, the company holds a dominant position in image sensor manufacturing expertise, having shipped 1.3 billion such devices in 2018.
“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. This will allow professional photographers, videographers and all other types of creators to capture content in ways that were simply not possible before,” said Neal Manowitz, deputy president of Imaging Product & Solutions, America, in an announcement statement.
The new camera offers a multitude of features. Some of them are: 15-stop enhanced dynamic range; five-axis optical in-body image stabilization; 10 fps shooting with full AF/AE tracking; and 567 phase-detection AF points for 74 percent coverage.
Its real-time Eye AF feature for still, movie, human and animal photography uses artificial intelligence to detect and process eye location data in real time; there are different settings to optimize this feature for photographing animals or humans.
Its advanced connectivity capabilities include wireless LAN functionality to support the 2.4GHz band as well as the high-speed 5GHz band for quicker data transfer. The camera is further said to be compatible with 52 native Sony E Mount lenses.
It carries a 5.76-million-dot UXGA OLED viewfinder and also boasts 4K movie recording capability and upgraded dust- and moisture-resistance.
The new camera also includes two UHS-II compatible media slots, allowing for higher overall capacity and faster read/write speeds – a feature that was added at user request, Sony said.
On the audio side, the 4-inch-long Sony ECM-B1M Shotgun Microphone, also introduced (September availability; $350) features eight high-performance mic capsules and digital signal processing, and provides three selectable directivity patterns with super-directional pickup; when connected to the Alpha 7R IV via its Multi Interface Shoe with digital audio interface support, audio is directly transferred to the camera in digital form without noise or degradation.
