Dual Pixel RAW is a Canon capture mode that records each pixel’s left and right photodiode data separately, storing approximately twice the file size of a standard RAW. The primary advertised use — bokeh shift, ghost reduction — is marginal in most practical situations. The genuinely useful application is microadjustment of the focus point in Canon’s Digital Photo Professional software after capture. At f/1.2 on the RF 50mm, the depth of field is thin enough that a focus acquisition that lands two millimeters in front of the intended plane produces a noticeably soft result.
