SONY’S A9III ARRIVES
SONY has announced the Alpha 9 Mark III, the world’s first full-frame camera with a global shutter, bringing with it huge advancements for high-speed photography.
A global shutter is a method of ending an exposure where all the image data is captured simultaneously. This is different to most existing shutter systems (electronic and mechanical) that start and end progressively and read data across the sensor.
The major benefit of the technology is the elimination of rolling shutter distortion, something that plagues many slow ‘traditional’ shutters found on mirrorless cameras, and gives the ability to sync with flash at almost any shutter speed.
The inclusion of a global shutter means the A9 III can sync at up to a mindboggling 1/80,000s in its single drive mode and 1/16,000s when shooting continuously, while also eliminating the need for High Speed Sync.
Previously, if a photographer released the shutter at a speed faster than the flash’s synchronisation speed, the amount of light would drop sharply, but with the global shutter it’s now possible to photograph scenes that could not be easily captured with conventional technology.
The global shutter also means the A9 III won’t be affected by banding, a side effect of artificial lights often found in indoor arenas.
