A compact, always-there camera with performance that rivals Sony's professional mirrorless models, the RX1R III is the long-awaited third generation of the fixed-lens full-frame camera. Featuring a higher resolution 61MP BSI CMOS sensor, improved AF and video performance, an updated body design, larger battery, and the same beloved ZEISS Sonnar T* 35mm f/2 prime lens from past models, this is the high-performance companion camera that melds extreme image quality with a highly portable size.
Full-Frame Sensor, BIONZ XR, AI Processing Unit
61MP Exmor R BSI Sensor
Borrowing the proven high-resolution sensor from the a7R V and a7CR cameras, the RX1R III features the full-frame 61MP Exmor R BSI chip, along with BIONZ XR processing, that achieves incredible resolution, high clarity, low noise, and a wide 15-stop dynamic range. The sensor's structure promotes impressive image quality, and a copper wiring layer dramatically improves data transmission speed for creating 14-bit, 61MP stills with a native sensitivity range from ISO 100-32000.
BIONZ XR Processing
Matching the sensor is the adept BIONZ XR processor, which offers up to 8x greater processing performance compared to previous generations, which enables faster overall performance, impressive image quality with wide sensitivity and dynamic ranges, and more fluent processing that's capable of handling a bevy of AI tasks and intelligent AF alongside imaging processes. This processing system also reduces rolling shutter and other motion distortions for clean rendering of moving subjects.
AI Processing Unit and Autofocus
Using dedicated processing, the RX1R III's autofocus is greatly benefitted by more intelligent subject tracking and recognition capabilities along with the reliable hybrid AF system Alpha cameras are known for. Real-time Recognition AF works with seven different selectable target types:
- Human, which tracks body and head positions for accurate portraits. Real-time Eye AF performance has also been improved by 60% thanks to the human pose estimation capabilities.
- Animal, Bird, and Animal/Bird modes are now 40% more accurate for tracking and recognizing a variety of animal types. Recognition of these subjects includes dogs, cats, birds and more, with the ability to pinpoint focus on eyes and recognize animal bodies and heads.
- Insect recognition offers even finer performance with the ability to detect the head or entire insect subject.
- Car/Train and Airplane recognition means the camera can detect the front part of a train, nose of an airplane, or easily detect the entire fast-moving subject.
- Real-time Tracking benefits from AI-based subject recognition for following moving subjects, making it particularly well-suited to sports and action subjects. Also, Human pose estimation allows the camera to distinguish between multiple people and maintain focus on the targeted subject; even if someone crosses in front, the camera maintains focus on the key person.
Advanced Fast Hybrid AF
- Covering 79% of the full-frame image area, or 100% of the APS-C cropped area, a Fast Hybrid AF system incorporates a dense 693 phase-detection point grid for quick and precise focusing in a variety of lighting conditions with sensitivity down to -4 EV. This focusing system is available for use in all recording modes, to benefit both video and stills applications.
- Full-time DMF (Direct Manual Focus) enables using the lens's focus ring for manual focus control at any time, making it easier to switch focus to a different subject even when working with AF.
Accurate Exposure and Color
Especially accurate metering and white balance is possible thanks to AI-powered algorithms, like Human Pose Estimation, to detect skin areas for more accurately balance exposures when shooting portraits. This AE method is approximately 20% more reliable, even in backlit or direct sunlight situations, or even when the subject is not directly facing the camera. Deep learning technology, along with external visible light and IR sensors, also contributes to more accurate color reproduction and auto white balance processing.
Step Crop Modes
Suiting a high-resolution fixed lens camera, the RX1R III introduces Step Crop modes that simulate the field of view of lenses other than the built-in 35mm lens. By default, changing these modes is set to the C1 button and lets you cycle between 50mm (29MP) and 70mm (15MP) settings to make tighter in-camera compositions.
Creative Looks
Also befitting a fixed lens, carry-everywhere camera, a series of new Creative Look settings have been added to impart a unique aesthetic to frames straight out of the camera. There are now 12 presets total, including the classic filmic FL setting; a new nostalgic FL2 film mode; a contrasty, slicker FL3 slide film-inspired look, and IN is reminiscent of instant film.
ZEISS Sonnar T* 35mm f/2 Lens
Featuring the same legendary lens from its predecessor, the RX1R III sports the classic ZEISS Sonnar T* 35mm f/2 prime lens—a fast wide-angle prime well-suited to everyday shooting needs.
- Bright f/2 maximum aperture is ideal for working in a variety of lighting conditions and also offers extensive control over depth of field, for highlighting subjects with selective focus.
- Optical design includes a series of aspherical elements to render images with a high degree of sharpness and accuracy.
- Nine-blade diaphragm contributes to a smooth bokeh quality.
- Dedicated macro position on the lens barrel allows focusing close-up subjects from a 7.9" to 11.8" range; when set to normal position, the lens focuses down to 11.8".
- Leaf shutter design enables flash sync at all mechanical shutter speeds up to 1/4000 sec.
Compact, Everyday Design
Portable Profile
Built to be a camera to take everywhere, much attention has been focused on keeping this camera as small as possible without sacrificing on quality.
- Measuring 4.4 x 2.6 x 2.9" and weighing 1.1 lb, the camera can easily fit in a coat pocket for everyday carry.
- Now compatible with the larger capacity NP-FW50 battery, the RX1R III is rated for approximately 300 shots per charge.
- Updated physical design maintains a flat top plate for a sleeker, minimalist appearance.
- New grip texture and matte coloring also contributes to a more discrete and appealing look and feel.
- Robust magnesium alloy body offers a durable profile and incorporates dust and moisture seals to protect against harsh environments.
EVF and LCD
- Another change in design from the previous generation, the RX1R III sheds the pop-up EVF design for a fixed position design, making the finder more reliable and intuitive to use. The EVF is a 0.39" 2.36m-dot OLED and has a 0.7x magnification.
- The rear LCD is a fixed 3.0" 2.36m-dot panel and its touchscreen design suits easy navigation and Touch Af and Touch Tracking controls.
Connectivity
- USB-C port for in-camera battery charging and data transfer.
- Micro-HDMI port can be used in conjunction with an external recorder or monitor.
- 3.5mm microphone port supports the use of an external mic.
- Multi Interface Shoe supports an external flash or working with the optional ECM-B1M Shotgun Microphone or XLR-K3M XLR Adapter Kit, which provide improved, clear audio recording sound by sending a digital audio signal to the camera, opposed to an analog signal.
- A nod to tradition, the shutter button is also threaded to accept a conventional cable release for making shake-free long exposures.
Video Recording
- Record full frame, 30 fps 4K video in 10-bit 4:2:2 using the advanced XAVC S-I format for consistent performance and quality at bitrates up to 300 Mb/s.
- The S-Log3 and S-Gamut3.Cine Gamma Curves allow for more than 15 stops of dynamic range and for increased post-production flexibility, including matching video from other Sony Cinema Line cameras.
- S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that is based on technology from the professional Cinema Line cameras, such as the VENICE. This color profile offers natural mid-tones, soft colors, and especially well-controlled highlights.
- Creative Looks can be baked into the recorded footage to create a specific mood during recording and minimize the need for editing.
- User-created LUTs and presets can be set for accurately monitoring footage or previewing a specific look during shooting and can be applied to the camera's monitor, EVF, or HDMI output.
