Review Excerpt

  • 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).

  • Superb image quality from RAW files; Improved dynamic range; Excellent high ISO performance; Fast 7fps burst rate with unlimited JPEG buffer; High-quality cinema 4K video; Built-in Wi-Fi; Dual Pixel CMOS AF is very good.

  • JPEG files look soft at default settings; 1/200s flash sync; 4K video codec is cumbersome; 29:59 continuous video recording limit.
