Panasonic‘s high-resolution entry into the full-frame mirrorless world, the Lumix DC-S1R pairs impressive and versatile imaging capabilities with a durable physical construction. The hallmark of the S1R is its full-frame 47.3MP MOS sensor, which is paired with a Venus Engine, to produce detailed, high dynamic range stills along with video recording up to 4K60p. The sensor’s design omits a traditional low-pass filter in order to achieve the greatest sharpness and on-chip aspherical micro lenses promote greater sensitivity, light condensation, and color response. Additionally, the sensor and processor work to achieve a top expanded sensitivity of ISO 51200 along with quick 9 fps continuous shooting rate. Complementing both stills and video capabilities, the image sensor also utilizes an advanced DFD contrast-detection autofocus system for quick and precise focusing and subject tracking. Additionally, sensor-shift image stabilization helps to minimize the appearance of camera shake by 5.5 stops for sharper handheld shooting.
Beyond the imaging attributes, the S1R is also distinguished by its body design, which incorporates an impressively high resolution 5.76m-dot OLED electronic viewfinder along with a 3.2″ 2.1m-dot triaxial tilt touchscreen LCD. The magnesium-alloy body is weather-sealed to permit working in harsh conditions and has a top status LCD for reviewing shooting settings on the fly. XQD and SD card slots offer flexible storage capabilities and Bluetooth and Wi-Fi connectivity afford remote camera control along with wireless image transferring to tablets and smartphones.
Featuring a full-frame 47.3MP MOS sensor, along with an updated Venus Engine, the S1R’s imaging capabilities have been optimized for high-resolution recording along with notable sensitivity, a wide dynamic range, and flexible recording modes. The sensor’s design omits a low-pass filter in order to maintain the highest degree of sharpness and on-chip micro lenses feature an aspherical design to improve light condensation and promote greater sensitivity, reduced noise, and more accurate rendering. An anti-reflective coating also helps to reduce surface reflections and flare for accurate color response. When combined with the Venus Engine’s processing power, noise levels are further suppressed throughout the sensitivity range, from ISO 100-25600, and processing capabilities further yield fast full-resolution continuous shooting speeds up to 9 fps with AF-S or 6 fps with AF-C, for more than 40 consecutive raw files.
Beyond stills shooting, the S1R is a capable video camera featuring up to UHD 4K60p recording with 4:2:0 8-bit color and unlimited recording times for the limit of the memory card. Also, high-speed recording modes for UHD 4K60, with 30 fps playback, and Full HD 180 fps, with 30 fps playback, offer 2x and 6x slower motion, respectively. Additionally, recording to an optional external recorder is possible, via the HDMI Type A port, and support for an external microphone and headphones are also available via dedicated 3.5mm jacks.
Helping to achieve the utmost sharpness when photographing handheld, Dual I.S. 2 combines the S1R’s 5.5 stop-rated 5-axis sensor-shift image stabilization technology with lens-based 2-axis image stabilization to compensate for a broader range of movement types to render sharper, clearer imagery. Dual I.S. 2 requires the use of compatible Lumix lenses featuring O.I.S. This stabilization system is able to compensate for approximately 6 stops of camera shake.
For accelerated autofocus performance, the DFD (Depth-From-Defocus) technology quickly calculates the distance to subjects and adjusts the focusing position in as little as 0.08 seconds, with sensor and lens communication occurring at rates up to 480 fps. This contrast-detection type focus method benefits both still and video recording modes, as well as subject tracking applications, using Advanced AI Technology, where subject type, color, size, and motion vectors are used to intelligently lock-onto the moving subjects and ensure precise focus. When working with portrait subjects, face/eye detection capabilities make it easier to photograph people and prioritize focusing as specifically as on a subject’s pupil. The focusing sensitivity and speed can be adjusted to further improve performance with certain subjects. It also features 225 AF areas, which provide excellent control over where the camera will focus. Additionally, supporting working in low-light conditions, a Low Light AF feature enables accurate AF performance down to -6 EV.
Benefitting manual focus operation, focus peaking is available that highlights bright edges of contrast with a colored outline for quickly recognizing your focus point, as well as Touch MF Assist for touch-to-focus operation. Other AF features include an AF Point Scope setting that temporarily magnifies the subject by 3x to 10x for confirmation of the focus position and a custom selectable AF zone for Multi AF / Custom Multi AF.
Utilizing the S1R’s video recording capabilities, a trio of still shooting modes are available for recording continuous 3:2 or 4:3 8MP stills at a 60 or 30 fps shooting rate or 18MP stills at a 30 fps shooting rate:
Bluetooth Low Energy (4.2) provides constant connection between your smartphone or table and the camera with minimal power consumption. For more robust wireless activities, IEEE 802.11ac and b/g/n support is also available for faster transmission and more fluid remote control and monitoring.
Complementing the camera’s wireless connectivity, Lumix Sync is an iOS and Android app designed to pair with the camera for smartphone or tablet-based remote shooting control and wireless image transferring.
Included with the camera body, the Lumix S 24-105mm f/4 Macro O.I.S. is a wide-angle to short-telephoto zoom featuring a constant f/4 maximum aperture. Its optical design includes a series of low dispersion and aspherical elements, which control a variety of aberrations, color fringing, and distortion in order to realize a high degree of sharpness, clarity, and color accuracy. Balancing its optical performance, this zoom is also unique due to is 1:2 maximum magnification ratio and 11.8″ minimum focusing distance to suit working with close-up subjects. Additionally, an Optical Image Stabilizer, which supports the camera’s Dual I.S. 2, helps to control the effects of camera shake for sharper handheld shooting, and the lens sports a weather-sealed design for use in harsh conditions.
