Review Excerpt

Handles even better than its predecessors; Absolutely spectacular images from the 36-megapixel image sensor; Unusually wide sensitivity range for its resolution; Improved performance and buffer depths; Improved video feature set; Impressive low-light autofocus
Prone to moire and false color with some subjects; No longer available with a low-pass filter; Demands excellent lenses for the best detail; White balance tends warm under tungsten lighting
Read our Nikon D810 Review

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
