Sony Alpha 7IV with 28-70mm Lens
The Sony a7 IV full-frame mirrorless camera with FE 28-70mm f/3.5-5.6 OSS Lens 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.
The Alpha 7 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 Alpha 7 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.
Sony have improved the dust and moisture resistance of the Alpha 7 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.
