Cyber-Shot DSC-RX10 mkIV
A versatile all-in-one solution, the Cyber-shot DSC-RX10 IV from Sony is a fast compact camera that covers a wide to telephoto zoom range. It uses an updated 20.1MP 1" Exmor RS BSI CMOS sensor in combination with a BIONZ X image processor to offer continuous shooting with AF/AE at up to 24 fps shooting at ISO 12800, alongside UHD 4K/30p or Full HD 1080/120p video recording. The sensor technology with back-illuminated and stacked technologies also provides notable image clarity with reduced noise, making the camera well-suited to working in low-light conditions. Other features include 40x super slow motion, an Anti-Distortion shutter, and focal-plane phase-detection AF points for faster, more precise focusing.
In total the DSC-RX10 IV's Fast Hybrid AF System is equipped with 315 Phase-Detection Points to dramatically improve autofocus speed for both stills and video. These phase-detection points provide approximately 65% frame coverage which works with a 25-area contrast-detection system to provide fast, accurate focusing in a range of situations. You'll be able to lock onto subjects in as fast as just 0.03 seconds, and enjoy AF tracking when shooting at 24 fps. Reduced blackout also makes subject tracking easier when using the EVF or LCD. Additionally an AF-A mode is now available, which will allow the camera to automatically switch from AF-S and AF-C mode as needed.
The camera uses a Zeiss Vario-Sonnar T* 25x Zoom Lens that spans a 24-600mm wide-angle to super telephoto equivalent focal length range, and has a variable maximum aperture of f/2.4-4. The optical design incorporates eight extra-low dispersion elements to control colour fringing and chromatic aberrations throughout the zoom range for increased clarity and colour accuracy. Five aspherical elements and an advanced aspherical (AA) element are also used to reduce spherical aberrations for improved sharpness and resolution. Finally, a Zeiss T* anti-reflective coating has been applied to individual elements to reduce flare and ghosting for increased contrast when working in strong lighting conditions.
Benefitting the lens' reach, Optical SteadyShot image stabilisation works to minimise the appearance of camera shake by up to 4.5 stops for sharper handheld shooting. The lens also features a rounded nine-blade diaphragm to produce attractive out-of-focus areas, and is able to focus as closely as 1.2" with a 0.42x maximum magnification for working with close-up subjects.
In addition to stills capture, you'll also be able to record UHD 4K video at 30/24 fps. By using a full pixel readout without binning, the camera collects about 1.7x the information needed for 4K output. This oversampling helps to increase clarity while reducing the impact of moiré and jaggies. Fast Hybrid AF is available during movie shooting for ensuring accurate, fast tracking using phase-detection AF points. The camera also offers Sony's advanced XAVC S format for recording a high bit rates up to 100 Mbps. When recording internally, users will record video with a 4:2:0 sampling at 8-bit, however, to even further improve image quality the RX10 IV has clean HDMI output for use with an external recorder. This allows users to capture 4:2:2 uncompressed video and save in an edit-ready format.
Video shooters will also benefit from advanced High Frame Rate shooting and super slow motion. In Full HD, a standard 120 fps setting makes it possible to capture slow motion when placed in editing software. In addition to this, the camera also offers a dedicated HFR mode, which will boost the cameras frame rate to up to 960 fps. A Photo Capture function is also built directly into the camera, allowing shooters to quickly save an 8.29MP still from their UHD 4K movies. Full HD can also benefit from this feature, where users will be able to pull a 2MP still. Both an external microphone jack and a headphone jack are available for using optional external mics and monitoring your audio in real time.
The RX10 IV is finished with a robust weather-sealed magnesium-alloy body, which includes both a 2.36m-dot OLED electronic viewfinder and a tilting 3.0" 1.44m-dot touchscreen LCD with a 109° upward and 41° downward tilting design. The intuitive body design also features three dedicated control rings on the lens that include a zoom ring, a manual focus ring, and an aperture ring that can be de-clicked for smooth, silent aperture adjustments. Wi-Fi and Bluetooth are also built-in, allowing for wireless image sharing and remote camera control from a linked smartphone or tablet.
