Sony a7 IV Mirrorless Camera Body
Sorry, we have no items in stock.
The Sony a7 IV full-frame mirrorless camera merges outstanding 33 megapixel image quality, 4K 60p video recording, refined handling and fast sharing abilities making it the perfect hybrid camera. With top of the line real-time autofocus in photo and video, the a7 IV gives the power of Sony’s best technology into the hands of creators and professionals.
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
The BIONZ XR engine, also used in the flagship α1 and α7S 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.
Best autofocus performance with Fast Hybrid AF
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 75933 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. The Alpha 7 IV shoots at up to 10 frames per second with fast buffer clearance to capture the best moment of the action unveiling in front of you.
4K 60p, 4:2:2 10-bit video recording
The α7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p17 recording, and when recording 4K movies at 30p, full-frame 7K21 oversampling22 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 format23 provides roughly twice the coding efficiency of MPEG-4 AVC/H.264.
The α7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6 and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin colour, plus soft colours and gorgeous highlights. Because it's in-camera, it's easy to create a more expressive look for your movie imagery without post-editing.
S-Log for colour matching with professional video equipment
The α7 IV provides S-Log2 and S-Log3 gamma curves, with the latter allowing capture of 15+ stops of dynamic range. The S-Gamut3 and S-Gamut3.Cine colour gamut settings make it easy to match α7 IV footage with footage from VENICE digital cinema cameras or Cinema Line cameras like the FX6 and FX3. The native sensitivity when shooting S-Log is ISO 800, and it can be lowered by as much as two stops (ISO 200-640) below the standard range to achieve extra low noise.
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 α7 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.
Bird mode for Real-time Eye AF, now available in movies
The Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR engine runs optimised AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.
Optical 5-axis in-body image stabilisation for 5.5-step compensation
The α7 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.
Vari-angle LCD monitor
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 α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 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 α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.
The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout.
Content always connected
a7 IV has livestreaming at up to 4K15p or Full HD 60p without the need for a capture card to keep you connected with your audience at all times. With the latest USB-C gen 3.2 compatibility, ultrafast Wi-Fi chip, and an automatic Bluetooth image backup mode on this streaming camera, transfer and share instantly your images with the world.
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.
Sony have improved the dust and moisture resistance of the α7 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 α7 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.
