Review Excerpt

  • Stylish "retro modern" design in two color schemes; attractive 3.3-inch AMOLED tilting touchscreen; new APS-C CMOS sensor with on-chip phase detection AF; better image quality, particularly in low light at high ISOs; faster all-around performance; improved Wi-Fi connectivity.

  • Camera feels more plasticky than expected when you pick it up; slower shot-to-speeds compared to rivals; poor buffer depth with raw files; aggressive anti-noise processing destroys detail in high ISO shots; display smudges easily and is rather dim; no EVF support.
