Exactly 20 years ago today, on June 5, 2006, Sony announced the Alpha 100, the camera that launched the Sony Alpha system. What began as an outsider’s entry into the DSLR market, built on the Konica Minolta A-mount platform acquired by Sony, has evolved into one of the most innovative and influential camera lines in the history of photography and videography.
Two decades later, Sony Alpha stands as a benchmark for hybrid photo/video performance, autofocus intelligence, resolution, and speed. From the groundbreaking in-body stabilization of 2006 to the global-shutter flagship of 2023 and the highest-resolution Alpha camera yet in 2026, the journey has left a significant mark on the industry.
Sony entered the digital camera arena by acquiring Konica Minolta’s camera division, inheriting the A-mount lens ecosystem. The Alpha 100 (10.2MP APS-C CCD) introduced SteadyShot INSIDE in-body image stabilization- a major first for compatible lenses at the time, along with the BIONZ processor and an accessible price point for enthusiasts.
The system quickly expanded:
The SLT line peaked with the Alpha 99 (2012), the world’s first full-frame SLT, delivering 24.3MP and full-time phase-detect AF.
In 2013, Sony fundamentally changed the industry with the launch of the Alpha 7 and Alpha 7R – the first full-frame mirrorless cameras. Compact, lightweight, and featuring hybrid AF and the new E-mount, they proved that professional image quality no longer required a bulky DSLR body. This was the true turning point. The E-mount system offered a shorter flange focal distance, enabling smaller, sharper lenses and paving the way for the vast native FE lens lineup we have today (while still supporting legacy A-mount glass via adapters).
Sony didn’t rest. Key milestones followed at an impressive pace:
Sony continued to break new ground:
Sony didn’t just compete; it often forced the entire industry to accelerate. The shift to mirrorless, the emphasis on hybrid video capabilities, compact pro bodies, advanced real-time AF (Eye AF, animal/bird/vehicle tracking), and stacked/global-shutter sensors all trace their significant momentum back to Sony’s Alpha developments.
