Review Excerpt

  • Phenomenal resolution and sharpness; Fine Detail Picture Style is like in-camera Unsharp Mask; Excellent print quality; Decent high ISO performance; Improved normalized dynamic range compared to 5D Mark III; Decent burst speed with good buffer depths; Built-in intervalometer & timelapse movie mode.

  • AF speed tested closer to consumer-level DSLRs; Dynamic range lower than competing models from Nikon & Sony; Lack of OLPF means subject to more aliasing artifacts with some subjects; No 60p video frame rate; No headphone jack; Timelapse video is only 1080p.

  • Unlocks the full potential of full-frame Pentax lenses; Excellent image quality; Great ergonomics and build; Very compact for full-frame; Decent performance; Fast autofocus with great low-light capabilities; Very wide sensitivity range; Bright, accurate viewfinder; Articulated LCD; Stabilization, Wi-Fi and GPS in-camera

  • No built-in flash strobe; Quite heavy compared to APS-C flagships; Somewhat soft images and blown highlights by default in JPEG mode; Warm Auto white balance indoors; Slow startup and buffer clearing; Small top-deck status display; Weak viewfinder illumination; Below-average battery life for DSLR
