Despite steady progress in digital imaging technology, mechanical limitations have restricted the benefits for digital SLR users to relatively minor improvements in size and features.
Now, with its ground-breaking innovation, Sony has transcended these limitations to redefine the future of interchangeable-lens cameras. The Exmor RS, the world's first 35-mm full-frame stacked image sensor with integral memory, has achieved speed and performance well beyond the capabilities of other models, and while containing fewer resources.
The α9's sensor delivers great leaps in performance and image quality by providing rock-solid AF; silent, vibration-free continuous shooting up to 20 fps and a blackout-freeviewfinder.
A sensor designed for performance
The new stacked CMOS sensor found in the α9 delivers professional performance, without the constraints of mechanical systems found in conventional digital SLRs.
An industry-first high-speed stacked sensor produces approx. 24.2 effective megapixel full-frame images, with up to 20x the readout speed thanks to integrated memory in the stack.
The α9 packs all the functionality of a conventional digital SLR's mirror, mechanical shutter, AF sensor and optical finder into the revolutionary Exmor RS image sensor, while also realising dramatic reductions to both the physical size and weight of the camera.
With the Exmor RS sensor, the α9 is approx. 20% smaller, in all three dimensions, than a conventional full-frame DSLR like Sony's first full-frame model, the α900. Easier than ever to carry anywhere, anytime.
The α9 is testament to Sony's dedication to functionality and image quality as well as greater shooting mobility. The evolution of the 35-mm full-frame CMOS image sensor in the α9 delivers leading image performance and contributes to significant camera size reduction.
Nearly 10 years ago, Sony stunned the industry with its first full-frame digital SLR, the α900 – weighing in at 850 g. Now, the new α9, at just 588 g, weighs 30% less, improving both mobility and stability.
