Product Description:
The latest sensor, processing engine, and AI-based autofocus work in tandem with cutting-edge still-photography and moviemaking technology to create a fresh, dynamic imaging experience. The α7 IV is the ideal hybrid, providing breathtaking still and movie imagery, along with flexible connectivity for on-the-spot transmission of your images.
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.
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.
The α7 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.
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.
Visible benefits of the powerful new 33.0‑MP sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery, and better colour reproduction, with higher subjective resolution resulting from improved algorithms. 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.
Broaden your creative palette with a selection of ten Creative Look presets. You can easily impart a particular mood in your still images, movies, and live streaming, and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting.
The built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes, and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions, as well as enhancing still shots and movies. Four level settings are available, so you can adjust the degree of the effect as you wish.
The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features. Improved face detection translates into 30% better eye-detection accuracy, while faster image processing yields higher accuracy when the subject is looking up, down, or sideways. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.
