Alpha 1

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 Support

• Making use of the high-resolution sensor and fast processing capabilities, UHD 8K 30p XAVC HS 10-bit 4:2:2 video recording is possible using the full width of the sensor, offering 8.6K oversampling for impressive sharpness and realism. For easy handling of this high-res recording mode, low bit-rate proxy files with HD resolution can be simultaneously recorded faster for playback. Also, 8K video at 400 Mb/s can be written to a V90-rated UHS-II SD card, or 200 Mb/s to a V60 card, and 8K can be output over HDMI in 8-bit 4:2:0 format.
• Recording up to UHD 4K is possible with frame rates up to 120p; when recording up to 60p the a1 offers full pixel readout and at 120p it uses a 10% crop. Oversampled 4K recording is also possible, via a 5.8K capture area, with a Super 35 crop. Internal 10-bit 4:2:2 sampling is also possible in all recording modes and, if recording externally via the full-size HDMI A port, 16-bit raw output is also possible from a 4.3K capture for even greater tonal reproduction and post-production flexibility.

Recording Flexibility

• The a1 employs a pair of codecs to suit different workflows: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at smaller bitrates and XAVC S-I, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s.
• High-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate playback set to either 30p or 24p or, if moving down to Full HD resolution, an effective 240p frame rate is also available for even greater motion control.
• No recording time limit allows for unlimited clip lengths and the camera's physical design features an improved heat-dissipating structure to promote longer possible recording times; longer than 30 minutes for 8K 30p or 4K 60p videos, or recordings done at 10-bit 4:2:0.

Advanced Color Control

• S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that matches the FX9 and FX6 cameras and 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.
• Affording extensive customizable color and gamma controls, the you can adjust the gamma, black level, knee, color level, and more. Also, users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility.
• HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing a 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

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 2x2 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.
