lpha a7 IV Mirrorless Digital Camera with 35mm f/1.4 GM Lens
Prepare to be inspired. The Sony Alpha a7 IV's true-to-life resolution and remarkable AI-powered autofocus complement a range of world-class features at the cutting edge of imaging technology. Delivering outstanding performance and excellent image quality in both stills and movies, the α7 IV's new 33.0 megapixel1 Exmor R CMOS image sensor provides high-speed readout, high sensitivity, low noise, and highly accurate colour reproduction.
The α7 IV uses the latest image processor to offer greatly enhanced performance, with improved image quality and colour reproduction. Fast processing speeds facilitate comfortable continuous shooting as well as responsive operation while performing data transfers.
In addition to boasting a larger pixel count and higher resolution than the α7 III, the α7 IV and its powerful Exmor R sensor represent a significant evolution of Sony's original image technology, for improvements that go beyond mere numbers. Experience new levels of colour gradation and detail rendering as well as soft, natural-looking human skin textures.
A classic wide-angle prime with an updated, sleek design, the Sony FAE 35mm f/1.4 GM is characterised by its speed and relatively compact form factor. The versatile focal length suits everything from street shooting to landscape and documentary subjects, and the fast maximum aperture excels in low light and for controlling depth of field. Also, as a G Master lens, it features an advanced optical design for well-corrected imagery with a high degree of sharpness and clarity.
Two XA (eXtreme Aspherical) elements and one extra-low dispersion element reduce a variety of aberrations, colour fringing, and distortion, and the optics are complemented by a Nano AR II coating that also suppresses flare and ghosting for improved contrast. Balancing the optics is an XD Linear Motor system that uses two separate focusing motors to deliver especially quiet, precise, and quick autofocus performance. The lens also sports a dust- and moisture-sealed design and fluorine-coated front lens element to support shooting in inclement conditions.
Camera Features:
- 5-axis optical image stabilisation. The α7 IV's high-precision stabilisation unit and gyro sensors work together with image-stabilisation algorithms to achieve up to 5.5 steps of shutter-speed compensation, to maximise the high-resolution performance of the camera's 33.0MP image sensor.
- Improved Real-time Eye AF. The high speed of the latest image processing engine provides a significant boost to Real-time Eye AF performance, even when the subject is looking up, down, or sideways. It is also possible to use Touch Tracking to initiate Real-time Tracking of any subject in the frame, simultaneously initiating Real-time Eye AF if an eye is detected, simply by touching the screen.
- Real-time Eye AF for birds. For the first time in the α series, bird-eye detection is available in movies as well as still shots – simply preset the subject to "bird". The camera's astonishing speed and precision allow automatic tracking of a specific bird, whether it's perched somewhere or in flight, keeping the eye in steady focus despite any fast and unpredictable movements.
- 4K 60p 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.
- 7K 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.
- All-Intra encoding supported in addition to Long GOP. All-Intra14 recording encodes every frame independently, at bitrates of up to 600Mbps, capturing complex motion more accurately and allowing more efficient editing workflows.
- Support for S-Cinetone, Creative Look and S-Log. 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-Log gamma to access the camera's full dynamic range (15+ stops) for smoother post-production workflows.
- New Breathing Compensation. 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.
Lens Features:
- As part of Sony's esteemed G Master series, this lens is designed to achieve notably high resolution and sharpness through the correction of a wide variety of spherical and chromatic aberrations. Additionally, these lenses feature robust and intuitive-to-handle physical designs to benefit both photography and cine applications.
- Wide-angle 35mm lens is designed for full-frame Sony E-mount mirrorless cameras; however, it can also be used with APS-C models where it provides a 52.5mm equivalent focal length.
- Notably fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also affords increased control over depth of field.
- Two XA (extreme aspherical) elements are incorporated into the optical design and feature superior surface precision for effective control over astigmatism, field curvature, coma, distortion, and other spherical aberrations for a high degree of sharpness and accurate rendering.
- One extra-low dispersion element is featured in the lens design and helps to reduce chromatic aberrations and colour fringing for improved clarity and colour neutrality.
- Nano AR Coating II has been applied to reduce surface reflections, flare, and ghosting for increased contrast and colour rendering in strong lighting conditions. This updated coating is better suited for larger, curved elements and is especially adept at minimising internal reflections.
- Two XD Linear Motors, along with an internal focusing design, provides quick, quiet, and precise autofocus performance. This design also contributes to more natural, intuitive Linear Response manual focus control and an AF/MF switch is located on the lens barrel for tactile control over this setting.
- A focus hold button is featured on the lens barrel for intuitive tactile control and rapid access to select settings.
- Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
- Dust- and moisture-sealed design better permits working in inclement conditions and rubberised control rings benefit handling in colder temperatures.
- Fluorine-coated front element resists dust, moisture, and fingerprints and is easy to clean.
- Rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
