A closer look at Sony's A7R IV full-frame, 61-megapixel mirrorless camera
The successor to Sony's highly acclaimed A7R III has arrived. Today, at an event in New York City, the company introduced its A7R IV, a full-frame mirrorless camera that comes with a whopping 61-megapixel Exmor R sensor. Sony says this new shooter is all about offering "medium-format-level" image quality in a package that's both compact and lightweight. In addition to that pixel-packed sensor, the A7R IV features a 15-stop dynamic range, ISO sensitivity up to 32,000, continuous shooting up to 10 frames per second (with auto-focus and auto-exposure tracking) and 567 phase-detection points cover around 74 percent of the frame. Simply put, this thing is a powerhouse.
24 hours with Sony's A7R II full-frame mirrorless camera
If that RX100 IV point-and-shoot isn't powerful enough for you, Sony has a couple other new cameras to fit your needs: the A7R II and RX10 II. For now, our focus is on the A7R II, a full-frame mirrorless beast that's been one of the most anticipated shooters of the year, and for good reason -- it packs high-end specs in a surprisingly small body. It's definitely smaller than your average DSLR. Sony's second-generation A7R comes with a whopping 42.4-megapixel Exmor R BSI CMOS sensor (35mm) and BIONZ X processor, both high-end components that are expected to make this one of the sharpest and fastest cameras on the market.
Sony A7 and A7R firmware update brings boosted performance, improved image quality

After updating to firmware version 1.2, A7 and A7R owners will be able to take advantage of boosted image quality, new applications and faster start-up times when the camera is turned on immediately after being powered off. On the IQ front, Sony's managed to reduce color noise in speed priority continuous mode. You may also notice reduced color artifacts at object edges in bright scenes while shooting video. As for the Play Memories Camera apps, firmware 1.2 adds in new Live-view Grading and Smooth Reflection tools. There's also better AE tracking in the Timelapse app. Finally, the update enables compatibility with the new 70-200mm full-frame lens.
