The Nikon D800 has been much criticized for its enormous megapixel count. And some have worried that packing 36 megapixels into a full frame sensor might lead to decreased low-light performance. These samples, however, push those worries aside. It's no D4, but for 36 megapixels, I think Nikon should win an award for this. Canon took a different route with the 22-megapixel 5D Mark III, but that paid off, too. See for yourself in the full post!
Nikon equivalents for the Canon shots below are too large to load here, so please visit the site here for images taken with the D800 in the same conditions, where you can find examples with noise reduction as well!
