This information applies to versions 4 and newer
DxO PhotoLab will accept DNG files created natively by supported cameras found in the list of supported cameras and lenses. DxO PhotoLab also supports DNG format if the original RAW format is supported, BUT only as long as they have been generated by Adobe Lightroom or Adobe DNG Converter (RAW DNG) without any further corrections (RAW-DNG) and without compression.
DxO PhotoLab also supports DNGs which were created with DxO PhotoLab and DxO PureRAW. However, automatic optical corrections and denoising will not be available for those DNGs as they have already been applied. So you'll see the icon for "no optical module available".

Cameras are supported by the version indicated in the list. RAW Converters are not backward-compatible.
