Overview
A flagship in the truest sense, the Sony Alpha a1 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.
50.1MP Exmor RS BSI CMOS Stacked Sensor
Newly developed 50.1MP Exmor RS full-frame sensor features a stacked back-illuminated design with integrated memory that maintains high image clarity and dynamic range while also enabling fast 30 fps shooting and and phase-detection AF. The 50.1MP resolution not only benefits stills shooters as it also offers full-frame 8.6K oversampling for 8K video recording.
BIONZ XR Processor
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.
Continuous Shooting Up to 30 fps
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 238 compressed raw frames, or 400 JPEGs, in one single burst.
Body Design and Connectivity
- 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. This viewfinder 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.
- 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.
- Redesigned 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.
- 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.
- 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.
- 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.
- Integrated PC sync terminal for wired flash sync with strobe packs or wireless radio remotes.
- Integrated Ethernet port offers up to 1000BASE-T speeds for quick wired LAN sharing and remote operation.
- 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.
- Built-in Wi-Fi enables the remote camera control and instant sharing of imagery to mobile devices for direct sharing online, and support for both 2.4 and 5 GHz bands also enables wireless tethered shooting support. This connectivity also provides remote camera control
- USB Type-C port can be paired with an optional Ethernet wired LAN adapter to provide 1000BASE-T connectivity, wired remote shooting, or FTP transferring.
