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

  • Excellent build and comfortable handling; Bright, roomy viewfinder and articulated LCD; Great image quality; Good performance for the class; In-camera stabilization, GPS and Wi-Fi; Incredibly feature-rich design.

  • Bulkier than APS-C DSLRs; Top ISOs are for the spec sheet, not the real world; JPEGs are a bit punchy by default; Slow startup; Below-average battery life; Only a relatively modest update to the K-1.
