Sony a1 Overview
A flagship in the truest sense, the Sony Alpha 1 is the one camera designed to do it all. Built without compromise, this full-frame mirrorless offers high-resolution for stills shooting, impressive 8K video recording, speed and sensitivity, and connectivity for the most demanding professional workflows.
Exmor RS Stacked Sensor and BIONZ XR Processor
50.1MP Full-Frame BSI CMOS Sensor and BIONZ XR
Newly developed 50.1MP Exmor RS full-frame sensor features a stacked back-illuminated design with integrated memory that maintains high image clarity, expandable sensitivity up to ISO 102400, and a 15-stop dynamic range while also enabling fast 30 fps shooting and and phase-detection AF. The sensor also enables recording lossless compressed raw files for flexible editing during post-production while maintaining a relatively lightweight file size. Additionally, the 50.1MP resolution not only benefits stills shooters as it also offers full-frame 8.6K oversampling for 8K video recording.
A revised BIONZ XR engine greatly benefits image processing capabilities throughout the camera system, including up to 8x faster processing, greatly reduced rolling shutter, and more fluent interface and file management handling speeds.
Up to 30 fps Shooting and Updated Shutter
- Efficient sensor design and processing enables high-speed shooting up to 30 fps at full 50.1MP resolution, with full AF and AE capabilities, when working with an electronic shutter. When working with the mechanical shutter, speeds are still kept high at 10 fps. Also, a large buffer memory permits recording up to 155 compressed raw frames, or 165 JPEGs, in one single burst at 30 fps.
- Suiting fast-paced continuous shooting is a blackout-free viewfinder experience, which makes use of a 240 fps refresh rate for fluent eye-level viewing.
- Updated electronic shutter offers silent, vibration-free performance and also supports anti-flicker shooting for working under fluorescent, LED, or other flicker-prone types of artificial light, even while shooting at 30 fps with 120 fps AF speeds.
- Due to quickened readout speeds, electronic shutter flash sync is possible up to 1/200 sec. Even faster flash sync speeds are available when using the updated mechanical shutter, too, which can sync at 1/400 sec in full-frame or 1/500 secwith an APS-C crop.
8K 30p and 4K 120p Video
Body Design and Connectivity
Tru-Finder EVF and Tilting Touchscreen LCD
- An impressive QXGA OLED Tru-Finder EVF features a high 9.44m-dot resolution and 0.9x magnification for exceptionally bright, clear, and detailed eye-level viewing.
- The EVF has a dedicated 240 fps High Quality+ setting for smooth motion rendering and the finder’s physical design has a long 25mm eye point, 41° field of view, and features a fluorine coating on the outermost viewfinder element to benefit cleaning.
- A 3.0″ 1.44m-dot tilting screen benefits working from high and low angles. This LCD is a touchscreen, too, for intuitive shooting control and menu navigation.
- Updated menu structure is more intuitive and complements having different workflows and settings selections for movie recording and stills shooting. The menu system also works in conjunction with the touchscreen design of the rear LCD.
Versatile and Durable Design
- Dual memory card slots both accept either CFexpress Type A or SD-type memory cards. The dual slot design allows for flexible file saving and handling and can be configured to partition file types or can be used for overflow recording. Additionally, both of the card slots are rated to support UHS-II memory cards for faster transfer speeds.
- Accepts the high-capacity NP-FZ100 rechargeable lithium-ion battery, which provides approximately 430 shots/90 minutes of recording per charge when using the viewfinder or 530 shots/95 minutes of recording per charge when using the rear LCD.
- Enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system compensates for five different types of camera shake encountered during handheld shooting of stills and video. Additionally, specifically for video, there is also an Active IS mode that adds even more precise stabilization methods for even smoother footage straight out of camera.
- Magnesium alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses, and the grip rigidity has been improved for more comfortable hand-holding.
- Extensive weather-sealing, including enhanced sealing around the battery cover, terminal cover, and chassis joints, has been employed to resist dust and moisture for reliable operation in harsh weather conditions.
Ports and Interface
- Full-size HDMI A port offers a more reliable connection when working with external recorders.
- A USB 3.2 Gen 1 Type-C port has been added, in addition to a micro-USB port, for faster, more reliable tethering support. The USB Type-C connection allows the camera to be charged or powered from the host power source while connected.
- PC sync terminal for wired flash sync with strobe packs or wireless radio remotes.
- Both 3.5mm headphone and external microphone ports facilitate greater control over audio recording.
- Multi Interface Shoe supports 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.
- Ethernet port supports 1000BASE-T wired LAN connection for transferring files over FTP.
Connectivity
- Built-in Wi-Fi and NFC enables the a1 to instantly share imagery to mobile devices for direct sharing online, and support for both 2.4 and 5 GHz bands also enables wireless tethered shooting support. Also, the 5 GHz band supports 2×2 MIMO for fast communication speeds and dual antennas ensure a reliable connection.
- Bluetooth connectivity allows for location data acquisition.
- Ethernet port offers up to 1000BASE-T speeds for quick wired LAN sharing and remote operation.
- When working over a wired LAN, the Remote Camera Tool 2.1 app now has been enhanced for a reduced release time lag and live view delays as well as support for remote SD card formatting, FTP server switching, and changes to the still image storage destination. Wired or wireless LAN transfers can also occur in the background, while continuing to shoot.
- Imaging Edge Remote for desktop supports PC Remote shooting via the Wi-Fi connection or tethered by the wired USB Type-C port. An updated data transfer control also makes it possible to transfer files from an SD card over Wi-Fi using the Imaging Edge Mobile app even when the camera is powered off.
- Transfer & Tagging add-on app can send FTP setting parameters from your mobile device to the camera, offers automatic data upload to an FTP server with attached metadata, and can perform automatic voice-to-text conversion.
Pixel Shift Multi Shooting
This unique compositing mode allows you to achieve even greater resolution than the 50.1MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures in order to acquire approximately 199MP of information for greater color accuracy and detail than possible with a single exposure. These files can then be merged together during post-production by using the Sony Imaging software suite.
