DxOMark Published The Sony a9 Sensor Review: 92 Points
DxOMark completed their full in-depth review for 24.2Mp sensor inside the Sony A9. The Sony a9’s 24.2Mp full-frame CMOS sensor delivers outstanding overall performance, achieving a DxOMark sensor score of 92 points, ranking it as one of the best sensors we’ve tested.
DxOMark from Conclusion:
No stranger to pushing the boundaries of digital camera design, Sony has delivered a powerhouse of a camera in the a9, which far outstrips the performance capabilities of most mirrorless cameras to date.
The a9’s key specifications, including the 20fps burst shooting with full AF/AE tracking, no EVF blackout, near-complete autofocus frame coverage, and silent operation, are going to be seriously attractive to any and all professional action photographers.
To help facilitate the super-fast performance, the a9 has taken a step back from the monster resolution of the A7R II, but its 24.4Mp chip should suffice for most, and overall its image quality is outstanding.
The Sony a9’s sensor ranks as one of the best we’ve tested at base ISO, with consistently good scores for dynamic range and color depth, and exceptional results for noise. At those crucial mid to high ISO sensitivities for action photographers, image quality is also excellent and on par with flagship Nikon and Canon sports DSLRs.
For the very best image quality, the A7R II offers better results for color, as well as almost twice the sensor resolution, but it isn’t a sports camera and can’t compete for performance against the a9, so they’re intended for different markets.
With a big body-only price tag of $4,500, the Sony a9 is squarely in the pro category, going head-to-head with the top-end Canon and Nikon DSLRs. With many pros already heavily invested in lenses and accessories for those systems, it’s going to be a tricky (not to mention expensive) to switch, but the Sony a9 has both the performance capabilities and image quality that make it a seriously tempting proposition.
