Review Excerpt

  • Very fast top frame rate; full-time phase-detect autofocus; Full 60p HD video; Excellent kit lens; Very good high-resolution sensor.

  • Heavy; EVF appears dim when used in bright light; AF tracking in Movie mode was unreliable in our testing.

  • Impressive 26x optical zoom lens delivers crisp images, even when at full tele; Comfortable, ergonomic camera build feels higher-end than its low price point suggests; Lots of effective, automated features make picture-taking a fun experience for the beginner.

  • DSLR-style camera body might attract enthusiasts who will be disappointed in the X-5's consumer focus; Frustratingly slow to use all around; AA batteries can fall out when retrieving the SD card; Some design quirks are off-putting.
