Review Excerpt

  • Small body pairs nicely with compact, retractable Power Zoom lens. Extremely fast autofocus. Worthwhile improvements in image quality. Touchscreen overlays can now be hidden.

  • LCD panel is prone to fingerprint smudges. Weak flash, and no hot shoe. Modest burst performance, and very limited buffer for raw shooting. Noise levels and dynamic range still lag competition.
