Review Excerpt

  • Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Sharp, detailed images with very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.

  • Can seem intimidating at first; Fewer autofocus points than competitors; Doesn't take advantage of high-speed UHS-I flash cards; Movie feature set is very dated and file sizes huge.
