24.2MP Full-Frame Exmor R BSI Sensor BIONZ X Image Processor
UHD 4K30p Video with HLG&S-Log3 Gammas
693-Point Hybrid AF System
Compact and capable, the silver Sony Alpha a7C mixes the quality and advantages of a full-frame sensor with an especially portable and sleek body design. Featuring a 24.2MP Exmor R BSI CMOS sensor, the a7C offers hybrid abilities to suit both photo and video recording needs along with a form factor for everyday, all-day carry.
The full-frame sensor and BIONZ X image processor offer up to a 15 stop dynamic range along with UHD 4K video recording, extended sensitivity from ISO 50-204800, and a top continuous shooting rate of 10 fps for working with moving subjects. The sensor also houses a Fast Hybrid AF system, which uses 693 phase-detection points and 425 contrast detection areas for quick, intelligent, and precise autofocus performance with support for Real-time Eye AF and Tracking AF technologies. Also benefiting both photo and video needs is 5-axis in-body image stabilization, which compensates for up to five stops of camera shake for sharper handheld shooting.
Compared to other a7-series camera bodies, the a7C has a distinctly sleeker profile that mimics the styling of a rangefinder, with an offset viewfinder and a streamlined top plate. The re-positioned electronic viewfinder is a 0.39"-type OLED with 2.36m-dot resolution and is complemented by a 3.0" side-opening vari-angle touchscreen LCD. Built-in Wi-Fi and Bluetooth also enable wireless connectivity for remote camera control and sharing files to a connected mobile device.
24.2MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
Featuring a back-illuminated design, the full-frame 24.2-megapixel Exmor R CMOS sensor works with the BIONZ X image processor to offer high-resolution stills and video while minimizing noise and improving speed. This sensor structure works with a gapless on-chip lens design and an anti-reflection coating to improve light collection and enhance detail. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution stills with a native sensitivity range from ISO 100-51200, which can be further expanded to ISO 50-204800. Also, it enables internal UHD 4K video recording with a wide dynamic range using the full width of the full-frame sensor. The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture an impressive 15-stop dynamic range at low sensitivity values.
The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for approximately consecutive JPEGs or 115 consecutive raw files, and with full-time AF/AE when working with either a mechanical shutter or an electronic shutter.
UHD 4K Video Recording in XAVC S Format
Internal recording of UHD 4K videos is possible in multiple frame rates up to 30 fps and using 2.4x oversampling renders greater detail and full pixel readout is possible for higher quality imagery with reduced moir and aliasing. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mb/s XAVC S format contained within an MP4 wrapper with 4:2:0 8-bit sampling. The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 8-bit sampling.
Affording extensive customizable color and gamma controls, the a7C allows users to adjust the gamma, black level, knee, color level, and more. Also, users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility.
