Full-frame imaging in a compact body
Superior light collection means high-quality, low-noise images
Bigger sensors create better images, and the α7C's full-frame sensor is much larger than the sensors in smartphones, compact digital cameras and similar-sized APS-C interchangeable-lens cameras. The resulting increased light collection allows for professional-quality images with reduced noise, and more retained detail in both shadows and highlights.
24.1MP Full-Frame BSI Sensor and Image Processing
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.
Fast Continuous Shooting and Recording Versatility
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.
Fast Hybrid Autofocus
- 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.
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 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.
5-Axis SteadyShot INSIDE Image Stabilization
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.
In very good condition, with approx. 696 actuations only.
