DxOMark Introduces “Perceptual Megapixel” Score

DxO Labs have launched a new measure of lens sharpness, dubbed “Perceptual Megapixel,” on their DxOMark website. Designed by DxOMark experts, Perceptual Megapixel attempts to quantify the sharpness “perceived” by the photographer while taking into account all the characteristics and defects of the lens and the camera. “This new unit of measure replaces the MTF scores that we have been publishing up until now.

We think this new measurement will be more understandable and practical for photographers who use our website,” explained Frédéric Guichard, Chief Scientific Officer for DxO Labs.
