4K 60p0 movies with smooth, natural-looking capture

It is now possible to record movies at up to 4K 60p with full pixel readout and without binning, taking advantage of the α7 IV's brand-new image sensor and wide dynamic range for smooth images of fast-moving subjects.

7K0 oversampling for beautifully expressive, richly detailed images 

When recording 4K movies at up to 30p, full-frame 7K oversampling is possible, resulting in high-resolution, highly detailed 4K. Select the mode that best suits your purpose, and let the camera deliver.

Next-level image quality with 10-bit 4:2:2 recording 

Make in-camera recordings with the amazing richness of 10-bit depth and 4:2:2 colour sampling, with either Long GOP or All-Intra frame encoding, for far greater flexibility in image grading, post-processing and compositing.

All-Intra encoding supported in addition to Long GOP

All-Intra recording encodes every frame independently, at bitrates of up to 600Mbps, capturing complex motion more accurately and allowing more efficient editing workflows.

Superior quality and smaller file sizes with XAVC HS

The XAVC HS recording format uses HEVC/H.265 encoding to achieve twice the compression efficiency of AVC/H.264 encoding, for superior image quality and smaller, space-saving file sizes.

Choose your look, for more expressive movies

Support for S-Cinetone™, Creative Look and S-Log3

The S-Cinetone colour matrix, based on technology acquired through development of CineAlta cameras such as the VENICE, produces an impressive look with beautiful skin tones without post-editing. The Creative Look presets create other interesting visual moods in-camera, or you can use S-Log3 gamma to access the camera's full dynamic range (15+ stops0) for smoother post-production workflows.

New Breathing Compensation0

The a7 IV leverages our parallel lens and camera development to provide innovative Focus Breathing Compensation, exclusively for Sony’s E-mount lenses. By minimising the field-of-view shift that can occur, during movie shooting, when you rack focus with some lenses, you can achieve impressive results – for new creative possibilities from a diverse range of Sony’s E-mount lenses.

Focus Map to visualise depth of field

Answering a request from professional creators, the brand-new Focus Map feature lets you easily visualise depth of field when you're shooting0 . In use, focus (depth map) information is overlaid on a display of the live view in real time, so you can easily see which areas are in or out of focus.

AF Assist0 supports focus transitions when using AF

Inherited from the Cinema Line FX6, the AF Assist function smoothly switches between auto and manual focus. Rack focusing is possible by rotating the focus ring to switch into MF and shift focus to a different subject, with AF resumed when ring rotation stops.

Focus fine-tuning for true creative freedom 

Fine-tuned focus features, also used in higher-end models like the α1 and the α7S III, enable creative movie options like rack focus, quick switches of AF target, and highly customisable subject tracking sensitivity.

High-performance ‘Active Mode’ image stabilisation 

Reliable support for handheld movie shooting

Active Mode0 stabilisation for movie shooting is built on the camera's highly accurate stabilisation unit, gyro sensors and sophisticated algorithms. It precisely detects the required amount of compensation and applies stabilisation, providing stable 4K movie shooting1 without compromising the α7 IV's compact size and mobility.

Beautiful imagery with better image stabilisation

Because the α7 IV records gyro and lens data as metadata, you can use Catalyst Browse/Prepare software  to further smooth camera shake and make adjustments to image stabilisation even after shooting.

Digital audio interface for excellent sound quality

The Multi Interface (MI) Shoe enables cable-less connection, directly transferring the digital audio signal for high-quality sound without degradation, while also supplying power and eliminating concerns about mic batteries.

Integrated microphone wind noise reduction

Using newly developed signal-processing technology, when wind-noise reduction is set to "Auto" and wind noise is detected, the noise will be greatly reduced without affecting other sounds.
