Panasonic’s Lumix DMC-GF5’s sensor received a mediocre rating of 50. This score ties it with the G3, and indicates that changes made to this newer camera were mostly cosmetic renovations made to the outside, and new software features found in the camera’s interior.
At 20.5 bits, the camera did register respectable color depth, and would make a good purchase for newbie photographers who enjoy taking portraits of friends and family.
The GF5 also had an acceptable performance in dynamic range, providing a maximum 10 EVs at around 160 ISO. However, detail preservation might be lost in shadows and highlights at higher ISOs, as the camera’s sensor starts a steady decline in dynamic range performance after 400 ISO.
The GF5’s significant flaw is its ISO. In the sports category, DxOMark scientists observed the camera’s image quality deteriorating after about 575 ISO. This makes it a problematic camera for photographers who love to take pictures in dimly lit or dark environments.
