5D3 vs D800: Comparing High ISO RAW
Mar 14, 2012

The Test:

  • These came from ISO 25600 RAW files

  • Used dcraw to convert to 16-bit TIFF before JPEG

  • No sharpening, No NR

  • Downsized both to 8 megapixels (PS Bicubic)

  • 5D3 exposure is much longer than D800. We will ignore because testers admitted that light source changes between tests.

The 100% Crops of 8 megapixels

So to summarize:

  • D800 has 63% more pixels

  • D800 has at least 2 stops more dynamic range at ISO 100

  • D800 looks equal or better than the 5D3 at ISO 25600

Sooo... exactly what did Canon gain by staying at 22 megapixels?
