Review Excerpt

  • Attractive body design; Well-built, weather-sealed body; Excellent image quality; Excellent image stabilization; Very fast autofocus.

  • Exposure compensation dial changes easily; Small buttons; No in-camera chromatic aberration correction; Bundled flash is weak; Video compression artifacts with rapidly-moving subjects.

  • Attractive, retro rangefinder-style design; Improved (excellent) still image quality that's even better thanks to second generation X-Trans sensor technology; Great, sharp f/2 35mm-equivalent lens; Overall better operation and performance than the X100; Addition of phase-detect pixels makes bright light autofocusing faster.

  • Low-light AF slow and inconsistent; Video quality, even at 60p, compromised by moire and lack of image stabilization; Combined four-way pad/Command dial means AF control points cumbersome to change; Too easy to bump control dials and change settings accidentally (especially the EV dial).
