Mid-Light Score

The Mid-Light Score is the average performance of a lens with a camera body the different focal lengthfor a defined exposure conditions.

It is equivalent to the DxOMark Score except that it is based on mid-lighting conditions (5,000 Lux and 1/125s exposure time). Mid-Light Score makes a lot of sense when evaluating lenses with camera used in good lighting conditions: particularly appropriate for medium-format cameras used in studio environments.
