Sensor and processor
33MP BSI Exmor R CMOS sensor
The new 33-megapixel full-frame Exmor R BSI CMOS sensor features a back-illuminated design that promotes high clarity, low noise, and vivid color rendition. This design is beneficial for working in low-light conditions and works in conjunction with a wide ISO 100-51200 sensitivity range. The sensor design also achieves an impressive dynamic range of approximately 15 stops, and files can be saved in raw, JPEG, or 10-bit HEIF formats.
BIONZ XR Processor
Thanks to the flagship-class BIONZ XR engine, high-speed image processing capabilities are available for fast continuous shooting, 4K video recording, and advanced AF tracking performance. Fast processing also helps reduce rolling shutter and other motion distortions for clean rendering of moving subjects.
In terms of shooting speeds, the sensor and processor allow shooting at up to 10 frames per second, using the mechanical or electronic shutter and with AF/AE enabled. In addition, the buffer allows recording of up to 828 consecutive uncompressed raw + JPEG images when using a CFexpress Type A card.
Video recording
4K 60p 10-bit video recording
- By fully utilizing the high-resolution 33MP sensor and fast processing capabilities, UHD 4K 30p XAVC HS 10-bit recording is possible using the full width of the sensor, delivering 7K oversampling for impressive sharpness and realism.
- There's also upsampled 4K recording, via a 4.6K capture area, with Super 35 cropping, which delivers UHD 4K output at up to 60p in 10-bit.
- No recording time limit allows for unlimited clip lengths, and the camera's physical design features an improved heat dissipation structure to promote longer recording times; over an hour of continuous 4K 60p 10-bit 4:2:2 recording, for example.
- The a7 IV uses a pair of codecs to accommodate different workflows: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at lower bitrates, and XAVC SI, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mbps.
S-Cinetone, S-Log3 and other color and gamma controls
- S-Cinetone can be used to provide distinct colors and healthy-looking skin tone rendering that matches the FX9 and FX6 cameras, as well as the a1 and a7S III, and is based on the technology of professional Cinema Line cameras, such as the VENICE. This color profile offers natural midtones, soft colors and, above all, well-controlled highlights.
- HLG (Hybrid Log-Gamma) support enables recording in a wide color gamut to produce HDR-ready content directly from the camera.
- S-Log3 is also available to produce a dynamic range of 15+ stops with increased leveling control in the mid-tone shadow regions of the image.
Fast Hybrid AF System
AI-based autofocus
Covering approximately 94 % of the image area, a Fast Hybrid AF system incorporates 759 phase-detection points for fast and accurate focusing in a variety of lighting conditions with sensitivity down to -4 EV. This focusing system is available for use in all recording modes, benefiting both video and still applications.
Real-time tracking and real-time eye AF
Borrowing from the flagship AF system, the a7 IV features fine-tuned subject tracking and detection capabilities that quickly lock onto subjects and fine-tune focus precisely on recognized subjects' eyes and faces:
- Real-time tracking is an AI-based subject recognition system that recognizes subject color, pattern, and distance information for high focusing accuracy and speed.
- Beyond simple subject tracking, Real-time Eye AF adjusts focus accuracy and recognizes the eyes of humans, animals, and birds for critical sharpness. Real-time Eye AF even maintains focus on a subject's eye as they leave and re-enter the frame, making it easier to work in more spontaneous shooting situations.
AF during video recording and additional focus modes
- Real-time eye IF is fully supported during video recording, for detecting and tracking the eyes of humans, animals and birds while shooting.
- For more control over how focus changes appear during recording, seven-step AF transition speeds and five-step AF subject shift sensitivity controls let you fine-tune how quickly focus moves from point to point and how smoothly focus changes occur.
- Focus Map is a unique way to visualize depth of field and works in a similar way to peaking with a colored overlay of the scene that indicates which parts of the scene are in front of and behind the point of focus based on the chosen aperture.
- A feature carried over from the FX6 digital camera, AF Assist lets you intuitively switch to manual focus control to adjust focus position when working with AF. It's a quick way to shift selective focus between various subjects in a scene while recording.
- A unique solution to compensate for the performance of certain lenses when focusing, Focus Breathing Compensation will automatically smooth focus transitions and maintain a consistent field of view when changing focus positions during a shot. This mode crops in the image slightly and corrects for any compositional changes detected during focusing. This feature is compatible with certain E-mount lenses, check the compatibility of respiratory compensation objectives here.
Body design, connectivity and streaming
Viewfinder and LCD screen
- An improved QVGA OLED Tru-Finder EVF features a 3.68m-dot resolution that is approximately 1.6 times higher than its predecessor for a sharper and clearer display. This viewfinder supports standard frame rates of 60fps and 120fps for smooth motion rendering and its physical design has a long 23mm eye point, 0.78x magnification and a 37.3° field of view.
- Perfect for vlogging or other self-recording needs, the 3.0" 1.03m side-opening vari-angle articulating screen can be used in a front-facing orientation or can be tilted up or down to accommodate working from high or low shooting angles. This LCD screen is also a touchscreen for intuitive shooting control and menu navigation.
Ports and interface
- The full-size HDMI A port provides a more reliable connection when working with external recorders.
- A USB 3.2 Gen 2 Type-C port has been added, in addition to a micro-USB port, for faster and more reliable tethering support. The USB Type-C connection allows the camera to be charged or powered from the host's power source while connected.
- 3.5mm headphone and external microphone ports allow for greater control over audio recording.
- Multi Interface Shoe supports working with the optional ECM-B1M shotgun microphone or XLR-K3M XLR adapter kit, which provide clear and enhanced audio recording sound by sending a digital audio signal to the camera, as opposed to an analog signal.
- The USB Type-C port can be paired with an optional wired Ethernet LAN adapter to provide 1000BASE-T connectivity, wired remote shooting, or FTP transfer.
5-Axis Image Stabilization SteadyShot INSIDE
- The improved 5-axis SteadyShot INSIDE image stabilization system, effective at 5.5 stops, compensates for five different types of camera shake encountered when shooting handheld photos and videos and allows users to confidently use any lens, even adapted lenses, for critical shooting without experiencing blur due to camera shake.
- For long focal lengths, the system will correct for height and yaw adjustments. Macro and high-magnification photography, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will benefit from the use of roll compensation. The 5-axis stabilization will work at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
- Additionally, specifically for video, there's also an Active IS mode that adds even more precise stabilization methods for even smoother footage straight out of the camera.
Advanced external flash control
Ideal for working with flash while photographing fast-moving subjects, P-TTL flash metering is possible between each exposure when working with lo-, medium-, or even high-speed continuous shooting modes. This helps maintain steady lighting during low-light bursts and greatly benefits working in changing light or low-light conditions. The updated flash control system also helps reduce flash firing lag, uses the camera's AWB information for natural color rendering, and supports adjustment of certain flash and transmitter units directly from the camera's interface.
Wireless connectivity and streaming
- Built-in Wi-Fi allows for remote camera control and instant image sharing on mobile devices for direct online sharing, and support for both 2.4 and 5 GHz bands also enables wireless shooting. This connectivity also provides remote camera control.
- Using the Imaging Edge mobile app takes advantage of Bluetooth to maintain a reliable connection between the camera and mobile device.
- Supports Visual Story for easy delivery of photos and videos to the cloud immediately after shooting.
- Live streaming is possible directly from the camera simply by connecting the camera to a compatible computer or mobile device via USB, allowing the camera's video and audio capabilities to be used for live social media and video conferencing.
- 4K 15p, FHD 60p/30p and HD 30p recording settings are available and there are also internal Creative Look and Soft Skin effects for refined image quality directly from the camera.
- Internal recording is supported to a memory card during live streaming.
- UVC and UAC standards are supported to improve picture and sound quality while streaming.
