SONY A7R IV - FULL FRAME CAMERA

Sony Alpha a7R IV mirrorless digital camera (body)

Moving to a realm of even greater resolution, the Sony Alpha a7R IV continues the remarkable series of full-capacity full-frame cameras, characterized by stunning photos and video performance and versatility. This fourth edition of the a7R contemplates the inclusion of an updated 61 MP CMSI Exmor R CMOS sensor and an improved BIONZ X image processor, which provide impressive image results with a marked smoothness, a dynamic range of 15 stops and, of course , speed. Shooting of up to 10 fps is possible along with the ability to record 4K30 UHD videos, both with support for real-time AF and tracking AF technologies. The revised sensor design uses a fast hybrid AF system, with 567 autofocus points with phase detection, for remarkably fast and accurate focusing performance. Despite being such a high resolution sensor, it is also distinguished by its flexible native sensitivity range of ISO 100-32000 to work in a variety of lighting conditions. In addition, benefiting from both the still images and the video operation, the a7R IV retains image stabilization with a 5-axis SteadyShot INSIDE INTERIOR shift, which is effective to minimize camera shake up to 5.5 stops
By balancing the merits of the image, the a7R IV also sees an updated physical design with a more robust weather seal to adapt to work in especially harsh weather conditions. In terms of ease of use, the OLED electronic viewfinder has been increased to a resolution of 5.76m-points for a clear display and the 3.0 "LCD touch screen with rear tilt has a resolution of 1.44m-points for clear reproduction, Live image capture and menu navigation Dual SD card slots are UHS-II rated for faster performance and the inclusion of a USB Type-C port allows for fast battery anchoring and charging in the camera. , Built-in Bluetooth and 2.4 and 5 GHz Wi-Fi. The bands allow wireless transfer and remote control of the camera from paired mobile devices.
Sony dedicated accessories
Complementing the camera body is a trio of accessories to increase battery life and improve audio recording capabilities when recording a video. The VG-C4EM vertical grip is the dedicated battery grip, which accepts up to two more NP-FZ100 batteries for extended shooting times. Its ergonomic design also improves handling when shooting in vertical orientation.

For enhanced audio recording, and to use the updated Multifunction Interface and digital audio interface of the a7R IV, is the ECM-B1M Shotgun Microphone, which delivers a digital audio stream directly to the camera for a cleaner and With little noise. For even more advanced audio control, there is also the XLR-K3M XLR adapter kit, which is a dual-channel digital XLR audio adapter for connecting external microphones to the camera while still benefiting from the digital audio interface.
61MP Exmor R BSI CMOS sensor and BIONZ X image processor
With a backlit design, the full-frame 61MP Exmor R CMOS sensor works with the BIONZ X image processor to deliver stunning high-resolution images and videos while minimizing noise, improving speed and reaching a wide dynamic range of 15 stops This sensor structure works with a chipless chip lens design and an anti-reflective coating, in addition to eliminating the optical low-pass filter, to improve light collection and improve detail. In addition, the copper wiring layer dramatically improves the speed of data transmission to create high resolution still images of 61MP of 14 bits with a native sensitivity range of ISO 100-32000, which can be further extended to ISO 50-102400 . In addition, it allows the recording of internal 4K UHD video with a wide dynamic range of 14 stops using the full width of the full-frame sensor or an APS-C size area.

The sensor and processor combination also offers fast continuous shooting of up to 10 fps at full resolution, up to 68 consecutive frames, with full-time AF / AE.
Fast hybrid AF system
An updated fast hybrid AF system now employs a combination of 567 phase detection points, covering approximately 99.7% of the height and 74% of the frame width, along with 425 contrast detection areas for autofocus and reliable and subject tracking. performance. This focusing system also achieves especially fast speed and reliable tracking, as well as an improved low-light focus response up to -3 EV.
