Sony has just revealed a new imaging device, the Sony Alpha 7 IV Interchangeable-Lens Camera (ILCE-7M4), featuring a newly developed 33 megapixel full-frame back-illuminated Exmor R CMOS image sensor. The new sensor promise to deliver superior image quality and Wide ISO sensitivity range of 50-204800.
The new sensor found in the Sony Alpha 7 IV is paired with the latest BIONZ XR processing engine and boasts advanced autofocus capabilities based on the flagship Alpha 1 model.
The new Sony Alpha 7 IV offers 15-stop dynamic range, Creative Look function, high-speed AF, uninterrupted continuous shooting at 10fps with AF/AE tracking, “tenacious” Real-Time Tracking, and 759 phase-detection AF points “in a high-density focal-plane phase-detection AF system that covers approximately 94% of the image area.”
Wildlife photography enthusiasts will be thrilled to know that, for the first time, Real-time Eye AF can now track birds’ and animals’ eyes for both still images and movies – in addition to humans.
Speaking of humans’ eye-tracking, it has also received an upgrade. Sony said that its detection accuracy for the human face and eyes has been improved by around 30% over the Alpha 7 III.
Other highlights include S-Cinetone for rich, cinematic look videos, 4K 60p recording in Super 35mm mode, up to 4K 30p recording with 7K oversampling in full-frame mode, 10-bit depth 4:2:2 color sampling, XAVC S-I intra-frame encoding, XAVC HD for doubled compression efficiency, 5-axis optical in-body image stabilization, built-in Bluetooth and dual-band WiFi, CFexpress Type A compatible media slot, a 3.68-million-dot OLED Quad-VGA viewfinder, a 3.0-type 1.03 million-dot side-opening vari-angle touch-panel rear LCD monitor, top-panel REC button, live streaming capability when connected to a computer or smartphone, a dual-layer mode dial with the lower layer for selecting shooting mode and the top layer for Auto/P/A/S/M and MR (Memory Recall).
While the camera has a magnetism alloy body, the body is also made of Sony’s original recycled plastic SORPLAS and it will come pack in packaging made of recyclable materials and less plastic.
