Sony Alpha 7 IV +24-105mm f/4 G Full Frame Mirrorless Camera | ILCE-7M4G

Newly developed 33.0MP back-illuminated CMOS image sensor

The full-frame Exmor R CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording at up to 60p. The sensor also provides improved colour reproducibility, low-noise performance at all sensitivities, 15-stop dynamic range on stills, and increased AF precision and focal stability.

BIONZ XR image processor for up to 8x20 processing speed

The BIONZ XR engine, also used in the flagship a1 and a7S III models, provides up to an 8x increase in processing speed. The engine concentrates real-time processing of AF, image recognition and image quality adjustment to minimise processing latency, for greatly increased movie and still processing power. User interface, network, and file management processing is distributed in order to deliver fast response regardless of real-time processing load.

4K 60p recording, 4:2:2 10-bit recording

The a7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p recording, and when recording 4K movies at 30p, full-frame 7K oversampling produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom. The XAVC HS file format provides roughly twice the coding efficiency of MPEG-4 AVC/H.264.

Optical 5-axis in-body image stabilisation for 5.5-step compensation

The a7 IV's high-precision stabilisation unit and gyro sensors work with stabilisation algorithms to achieve up to 5.5 steps of shutter-speed compensation, to maximise the performance of the camera's 33.0MP sensor. This in-body stabilisation allows effective use with a wide range of lenses. The live monitor view shows the stabilised still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens, and it can be used in conjunction with the MF Assist and Focus Magnifier features.

Hand-held movie shooting with Active Mode

Active Mode uses the camera's stabilisation unit, gyro sensors and sophisticated algorithms for highly effective in-camera optical image stabilisation during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilisation in all formats, including 4K, without compromising the a7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilisation can be applied for ultra smooth shots using Catalyst Browse/Prepare software.

Fast Hybrid AF with improved speed, precision and tracking

Using a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely even on small subjects or on people posed in front of a nighttime background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 759 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analysed in real time by the latest powerful processing engine to achieve the AF system's impressive results.

AF control through touch operationAF control through touch operation

Touch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots.

Vari-angle LCD monitor for greater freedom when shooting

The large, side-opening 3.0-type 1.03-megadot touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings, and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting, or very low ground-level shots.

3.68 megadot high-definition Quad-VGA OLED viewfinder

The a7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the a7 III viewfinder, with a 37.3° FOV and a 23mm high eyepoint. With high resolution, improved electronic viewfinder image quality, and fogging and dust resistance (including significantly improved internal fogging resistance relative to the a7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.

Instant real-time live streaming via USB connection

Live streaming is as easy as connecting to a computer through a USB connection, and you can choose from four different output formats, including high-resolution 4K video. You can select whichever configuration is best for current network conditions and the devices used, and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.

Dual media slots, with CFexpress Type A support

Dual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards, and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting as well as high-resolution, high-bitrate 4K movie recording.

Reliable, robust engineering

We have improved the dust and moisture resistance of the a7 IV to provide outstanding reliability even in challenging outdoor shooting environments. Design refinements include more sealing at body seams and the battery compartment cover (compared to the a7 III), a redesigned lens lock button, and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover, and internal frame provides excellent durability.
