EOS 5D Mark IV: Dual Pixel RAW and DLO

The EOS 5D Mark IV features two useful image technologies – Dual Pixel RAW to give you post-shooting control of (among other things) the maximum area of sharpness and Digital Lens Optimizer to maximise the performance of your lens by correcting for lens distortion and sharpness. If you switch on DLO and then switch on DP RAW you’ll find that DLO will not function and the setting will have been turned to ‘disable’ automatically. Before shooting, you should decide whether DLO or DP RAW is going to be of most use given the subject you are shooting. If you wish to use both, then shoot with DP RAW and then use the Canon DPP software to apply DLO to the image.
