Review Excerpt

  • Very good image quality; More consumer-friendly control setup than NEX-7 but more advanced (actual Mode dial) than step-down models; OLED EVF and 3-inch tilting LCD monitor provide viewfinder flexibility; Fast and decisive AF on stationary subjects, and good continuous AF on normal moving subjects; Full HD 1080p video recording at up to 60p.

  • Hybrid AF system speed and accuracy still lags somewhat behind higher-end DSLRs; Wi-Fi features still rudimentary (join the club); LCD is not a touchscreen; User interface foibles.
