Review Excerpt

  • Solid, ergonomic body design; Stunning, highly detailed photos, thanks to 24.1MP sensor upgrade and removal of optical low-pass filter; Cool 1.3x crop mode extends reach to nearly 2x the full-frame equivalent; Records Full 1080p HD video at up to 30fps with full-time AF; Many pro-level features packed into a consumer-friendly body at reasonable price.

  • Shallow buffer that hampers continuous burst shooting; AF slightly slower than average for its class; No real-time aperture control while in Movie mode (among other quirks); More noticeable moire patterns and aliasing artifacts (but only found when shooting fabrics with strong, distinct patterns).

  • Excellent image quality with lots of fine detail; Very good high ISO performance; Good dynamic range; Good print quality; Deep buffers with JPEGs; 1080/60p video; Uncompressed HDMI output.

  • AF struggles in low-light; Contrast-detect AF in live view is slow; Buffer depth is shallow with RAW files; No AE bracketing; No built-in Wi-Fi.
