Buy the Pentax K-S1

Review Excerpt

  • Noticeably better sharpness than standard K-5 II; Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.

  • Prone to moire, aliasing, and false color artifacts; 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.
