Product Description

First Full-Frame Global Shutter Mirrorless Camera The a9 III by Sony marks the debut of the world's initial full-frame mirrorless camera equipped with a global shutter. This innovation represents a significant advancement over the traditional rolling shutter technology that has been in use for many years. The global shutter allows for virtually instantaneous and synchronized capture of all 24.6MP, eradicating issues like skew and other artifacts commonly associated with rolling shutters. Moreover, it outperforms mechanical shutter technology in every aspect, rendering the physical shutter redundant in the a9 III. Never Miss a Moment In addition to the sensor's core technology, the a9 III introduces new features that unlock the camera's full potential. One such feature allows users to configure the camera to start buffering images when the shutter button is half-pressed, with an adjustable setting between 0.05-1.0 seconds. These buffered images are then saved to the memory card upon full shutter press. Thanks to the Speed Boost and the strategically positioned C5 button near the grip on the camera's front, users can swiftly switch between their standard continuous shooting frame rate and a faster one to ensure they capture the perfect shot. Photographers will have the flexibility to choose from various frame rates, with options going up to 120 fps. Professional Quality Video Global shutter technology in the a9 III provides substantial advantages for video production, completely eliminating shutter and banding artifacts. Beyond this, the a9 III offers a range of noteworthy video enhancements compared to its predecessor. It excels at capturing and downsampling the entire 6K image area, resulting in impressive UHD 4K video at up to 60 frames per second. Additionally, it has the capability to record 4K at a remarkable 120 frames per second with no cropping. Ergonomic Body Design The introduction of the new Alpha-series cameras brings about subtle adjustments and refinements aimed at enhancing the system's ergonomic usability. The a9 III incorporates a number of these updates: What is a Global Shutter? Global shutter is a photographic technique that captures all image data simultaneously, distinguishing it from conventional shutter systems that progressively initiate and conclude exposure across the sensor. This method offers various advantages, including the elimination of the common rolling shutter distortion observed in videos and with slower electronic shutters. Another significant benefit is its compatibility with flash synchronization at virtually any shutter speed. In this context, the duration of the flash burst sets the limit, rather than the time required to close the shutter, which in turn determines the shortest duration for full sensor exposure. For instance, Sony asserts that the a9 III can sync at all shutter speeds, including ultra-fast ones up to 1/80,000 second. Furthermore, a global shutter effectively eliminates the banding issue that can arise with progressive shutters when capturing images under flickering lights. Since the entire image is captured at precisely the same instant, there is no discrepancy in the recording of different phases of a light's flicker cycle across different parts of the image. While exceptionally high shutter speeds may capture the refresh cycle of an LED signboard, any resulting artifacts are attributed to the LEDs themselves, as the camera faithfully records a single moment in time. - Sony A9 III Mirrorless Camera
