16MP APS-C Sensor: Pairs with the BIONZ image processor for responsive performance and solid image quality across a range of shooting conditions.
In-Body Image Stabilization: Sensor-shift stabilization works with any compatible A-mount lens, compensating for camera shake without relying on optical stabilization in the lens.
