The sensor and processor combination enables 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.
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.
- Covering a majority of the image area, a Fast Hybrid AF system incorporates 693 phase-detection points along with 425 contrast-detection areas for quick and precise focusing in a variety of lighting conditions with sensitivity down to -4 EV.
- Lock onto subjects quickly using Real-time Tracking for AI-based tracking on moving subjects or touch tracking for manual selection of the subject.
- Real-time Eye AF, suitable for both humans and animals, also ensures critical sharpness when shooting portraits.
- 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 moiré and aliasing.
- Full HD 1080p recording is also supported in frame rates up to 120 fps, and both 4K and UHD 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:
- 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.
- HLG (Hybrid Log-Gamma) support permits recording within a wide color gamut for producing HDR-ready content directly from the camera.
- S-Log3 is also available for producing a 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
Despite the sleek stature of the a7C, it features a 5-stop effective 5-axis SteadyShot INSIDE image stabilization system that compensates for various types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.
For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
- Compact and lightweight body design, along with a rangefinder-inspired layout, make the a7C a sleek and portable camera for everyday shooting. Compared to other a7-series cameras, the a7C is approximately 20% smaller and lighter, akin to the size of an APS-C-format camera.
- A 0.39″-type XGA OLED electronic viewfinder is featured and has a 2.36m-dot resolution and 0.59x magnification for bright, clear viewing in high detail.
- Rear 3.0″ 921.6k-dot rear LCD features a side-open vari-angle design along to benefit working from high, low, and front-facing angles. It’s also a touchscreen for intuitive control and playback.
- Magnesium-alloy chassis along with a weather-sealed design offers a durable overall construction for use in a variety of conditions.
- The large-capacity NP-FZ100 battery offers approximately 740 shots per charge when working with the rear LCD or 680 shots per charge when working with the EVF.
- Single SD memory card slot is rated to support UHS-II memory cards for fast transfer speeds.
- A USB 3.2 Gen 1 Type-C port offers for fast and reliable tethering support and also allows the camera to be charged from the host power source while connected.
- Multi Interface Shoe supports working with the optional ECM-B1M Shotgun Microphone or XLR-K3M XLR Adapter Kit, which provide improved, clear audio recording sound by sending a digital audio signal to the camera, opposed to an analog signal.
- Both 3.5mm microphone and headphone ports are available for greater audio recording control.
- Built-in Wi-Fi enables the a7C to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. Support for both 2.4 and 5.0 GHz bands also enables wireless tethered shooting support.
- Bluetooth connectivity allows for location data acquisition.
- NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and mobile device. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera’s shutter.
