Sony a7 IV Mirrorless Camera

Sony a7 IV Mirrorless Camera Body
The Sony a7 IV is the definitive hybrid mirrorless camera, pushing far beyond the boundaries of a standard baseline model. Perfectly balancing an advanced 33MP Exmor R full-frame sensor with the flagship BIONZ XR processing engine, it delivers an uncompromising mix of high-resolution stills and professional 4K video. Armed with an AI-driven real-time tracking autofocus matrix, up to 15 stops of dynamic range, and broadcast-ready color profiles like S-Cinetone, the a7 IV is the ultimate daily workhorse for commercial photographers, independent filmmakers, and multimedia content creators.

Next-Generation Sensor & Processing Power
33MP Exmor R BSI CMOS Sensor: The newly developed back-illuminated full-frame sensor delivers exceptional image clarity, vibrant color rendering, and low noise performance across a native sensitivity span of ISO 100–51,200. It captures a vast 15-stop dynamic range, outputting high-fidelity RAW, JPEG, or efficient 10-bit HEIF files.

Flagship BIONZ XR Engine: Borrowed from Sony’s high-end cinema and sports bodies, this extreme-speed processing engine powers blistering operational responses, accelerates continuous autofocus calculations, and substantially minimizes rolling shutter distortion.

10 fps High-Speed Bursts: Fires continuous bursts up to 10 fps using either the mechanical or electronic shutter with full AF/AE tracking engaged. An expansive internal buffer allows you to capture up to 828 consecutive uncompressed RAW + JPEG frames when using a CFexpress Type A card.

Professional 10-Bit 4K Video Pipeline
Oversampled 4K 60p Recording: Captures breathtakingly sharp UHD 4K at 24p/30p using the full width of the full-frame sensor with 7K oversampling. High-action 4K 60p can be captured in 10-bit 4:2:2 depth using a Super 35mm (4.6K oversampled) cropping profile.

Unlimited Recording & Heat Dissipation: Built with a high-efficiency internal heat-dissipating structure that eliminates the traditional 29-minute recording limit. The camera confidently handles over an hour of continuous 4K 60p 10-bit 4:2:2 capture without overheating.

Advanced Codec Architecture: Offers XAVC HS (utilizing highly efficient H.265 compression to retain exceptional detail at lower bitrates) alongside XAVC S-I (an all-intraframe codec providing robust, editing-ready files at bitrates scaling up to 600 Mb/s).

Cinema Line Color Metrics:

S-Cinetone: Delivers the identical organic mid-tones, natural skin tones, and soft highlight roll-offs used in Sony’s professional VENICE, FX6, and FX9 cinema systems.

S-Log3: Unlocks the full 15+-stop dynamic range of the sensor, offering complete exposure control and latitude in the shadows and mid-tones for high-end color grading.

HLG (Hybrid Log-Gamma): Enables immediate recording inside a wide color gamut for instant, HDR-ready playback workflows without mandatory color grading.

AI-Driven Fast Hybrid AF Matrix
759-Point Phase-Detection Area: Features a massive 759-point phase-detection array covering approximately 94% of the image area, maintaining surgical focus accuracy in extreme low-light environments down to -4 EV.

Real-Time Eye AF & Tracking: Utilizes advanced AI subject recognition to analyze color, patterns, and depth in real time. Real-time Eye AF locks onto and tracks human, animal, and bird eyes with pinpoint precision across both still capture and live video modes.

Cinematic Video Focus Utilities:

Focus Map: Overlays a colorful depth-of-field visual onto the screen, showing exactly what parts of the scene are in front of or behind the focal plane based on your current lens aperture.

AF Assist: Lets you intuitively grab the manual focus ring to make immediate micro-adjustments during active autofocus tracking, carrying over a signature workflow feature from the FX6 cinema camera.

Breathing Compensation: Eliminates distracting focal breathing artifacts by automatically applying a minor electronic crop to preserve a perfectly consistent field of view when racking focus (compatible with select Sony E-mount lenses).

Body Architecture, SteadyShot, & Live Streaming
3.68m-Dot Quad-VGA EVF: An upgraded electronic viewfinder featuring 1.6x higher resolution than its predecessor. It supports a switchable 60 fps or 120 fps refresh rate for ultra-smooth motion tracking and a comfortable 23mm eye point.

Vari-Angle Touchscreen LCD: Outfitted with a side-opening 3.0″ 1.03m-dot vari-angle articulating touchscreen display that can flip forward for vlogging or swivel freely to comfortably accommodate ultra-low and high shooting angles.

5.5-Stop 5-Axis SteadyShot INSIDE: Enhanced in-body image stabilization compensates for pitch, yaw, roll, vertical, and horizontal shift artifacts. An advanced electronic Active IS mode can be layered on during video recording to deliver stable, handheld footage straight out of the camera.

Pro Interface Connectivity: Features a full-sized HDMI Type-A port for rugged field monitor connections, a fast USB 3.2 Gen 2 Type-C port (supporting continuous host bus power and charging), dedicated 3.5mm headphone/mic jacks, and a digital Multi-Interface Shoe.

UVC/UAC Instant Live Streaming: Supports modern plug-and-play streaming capabilities via a direct USB link to a computer or mobile device. Broadcasts high-quality 4K 15p or Full HD 60p video and clear audio natively without needing an external capture card, all while saving a backup copy to the internal memory cards.
