Imaging Sensor and Processor
Revolving around the core of a 20.2 megapixel 1″ Exmor R CMOS sensor and BIONZ X image processor, the RX10 is able to record high-resolution still imagery and full HD 1080i/p video with especially notable low-light quality and a native sensitivity range of ISO 125 to12800. The back-illuminated design of the sensor enables this broad sensitivity range and, with the aid of the image processor, achieves well-detailed imagery with minimal noise to better support working in dimly lit conditions.
An improved area-specific noise reduction technology analyzes specific zones of an image and automatically applies adaptive noise reduction based on detected imaging patterns for optimized clarity and detail in difficult lighting. The processor is especially beneficial in regard to producing an extended range of tones and smooth color gradations as well as enhanced detail through the reduction of overly sharp digital artifacts for more realistic-appearing image quality. Fully manual exposure control is possible and the ability to record images in Sony’s ARW RAW format facilitate greater control over the final appearance of imagery during post production.
Zoom Lens and Autofocus System
Complementing the imaging sector of the RX10 is the inclusion of an 8.3x optical zoom Carl Zeiss Vario-Sonnar T* f/2.8 lens, which provides a 35mm equivalent focal length of 24-200mm. The wide-angle-to-telephoto perspectives encompassed by this zoom range are significantly aided by the constant f/2.8 maximum aperture that allows selective focus control and suitable light-gathering abilities at any focal length position.
Diffraction-reducing technology benefits working with smaller apertures by applying aperture-specific filter processing to images to suppress and compensate for optical diffraction that typically degrades resolution, clarity, and sharpness. Seamless close-up shooting is also supported, which no longer requires the need to switch to a dedicated macro mode, for focusing on subjects as close as 11.8″ away. Also benefitting full use of the lens and its broad coverage is the integration of Optical SteadyShot image stabilization, which works to minimize the appearance of camera shake to avail the use of slower shutter speeds and longer focal length settings. A newly designed Direct Drive SSM (Super Sonic wave Motor) is used to drive the autofocusing mechanism in a quick, smooth, and highly precise manner. Due to the smaller design of the lens itself, the focusing motor can function in a more productive and precise way, even at the telephoto end of the zoom range. Extending the focusing performance, too, is the option to decide upon three concentric Flexible Spot frames for greater versatility and accuracy in how focus is determined when compared to more traditional fixed-position focusing frames.
When working with moving subjects, Lock-on AF can quickly determine focus on a recognized subject, alter the target size depending on subject-specific characteristics, and then maintain continuous focus while the subject moves. In regard to portraiture, a newly developed detail-oriented focusing method, Eye AF, is available and can prioritize a subject’s pupil and dedicate focusing performance on that for sharply rendered portraits. When working with Eye AF, a green confirmation frame will be displayed over the selected eye when focus has been acquired, ensuring critical focus on the most important subject within the frame.
Hi-Def Movie Recording
Full HD 1920 x 1080 video recording is supported in both 60i/p and 24p frame rates using the high-quality AVCHD Progressive format with bit rates as high as 28Mbps. Recording in the Internet-friendly MP4 format is also supported for a more streamlined workflow if recording simply for web playback. Full manual control over exposure settings is possible during movie recording, as well as use of the optical zoom lens, and advanced audio control options are also available. External microphones can be utilized for higher-quality sound and a dedicated headphone jack is integrated into the design for real-time audio monitoring over controllable sound levels.
Rugged Body Design
Incorporated within the body design of the RX10 are both a high-resolution electronic viewfinder as well as a large tilting LCD screen. The XGA OLED Tru-Finder integrates four dual-sided aspherical elements into its optical design to promote greater visibility from edge to edge with a large 33-degree viewing angle. As an alternate viewing means, a 3.0″ 1,228k-dot Xtra Fine LCD monitor is available and features tilting design for easier viewing from both high and low angles. The LCD also utilizes White Magic technology to improve the effective monitor brightness to better support working in sunny conditions.
Surrounding the two viewing options, a range of seven customizable buttons can be independently programmed to control up to 40 different camera settings depending on personal needs, and an intuitive Fn button allows you to pull up a list of the most frequently used settings for easier access. A manual control ring is also employed, surrounding the lens, for direct control over zoom or focusing, depending on the focusing mode in use. Aperture control can be handled on the control ring, too, and can be set to give a physical click-stop design for assurance or a silent, seamless design for quiet changing of f/stop settings. Exposure settings can all be viewed via a display panel on top of the camera for an expedited method of confirmation. A Multi Interface Shoe enables the attachment of external flashes or other accessories.
The top and front casings of the body itself are constructed from magnesium alloy to lend a solid, robust feeling with enhanced durability. The RX10 is also design to be dust and moisture resistant to support its use in inclement conditions.
Connectivity and Accessories
Built-in Wi-Fi support with NFC (Near Field Connectivity) provides a seamless method for linking mobile devices to the RX10 for direct image transferring for instant uploading and sharing online. The Wi-Fi support also permits linked mobile devices to release the shutter from a distance, serving as a convenient remote control.
