The D850’s fast, ultra-high-resolution FX-format sensor uses 45.7 megapixels of effective resolution to deliver richly detailed 45.4 MP files. Print ultra-high-resolution images in ultra-large formats. Shoot true full-frame movies at 4K. The back-illuminated CMOS sensor has no optical low-pass filter and incorporates gapless on-chip micro-lenses as well as an anti-reflective coating. Incoming light reaches the photodiodes more efficiently so you get exceptional detail and incredible dynamic range. And the 153-point AF system, inherited from the D5, assures you of the pin-sharp focus and wide coverage you need for ultra-high-resolution full-frame images.
