The Nikon D3X is a professional full-frame digital SLR introduced by Nikon in late 2008, sitting at the top of the brand's DSLR line alongside the speed-focused D3. It was positioned as a high-resolution studio and landscape tool, competing with medium-format digital backs at a fraction of their launch price.

At UK auction today, hammer prices for the D3X span roughly £250 to £690, with a median around £450 — these are saleroom results, so the figure reflects what the body is worth wholesale rather than what a dealer sells for. Condition drives the spread: clean, low-shutter-count bodies with original batteries and chargers sell for more, while cosmetically worn or untested examples are what push the lower end of the range.
