Panasonic Leica DG Summilux 12mm f/1.4 Asph review – Focus
Autofocus uses an internal focus system driven by a stepper motor, and as a result it’s very fast, essentially silent, and as consistently accurate as we’ve come to expect from Micro Four Thirds. With this kind of fast wideangle prime, however, the camera can be relatively easily fooled by images that contain both depth and lots of fine detail. In this case it’s easy to switch to manual focus with a flick of the AF/MF switch on the side of the barrel, and while accurate manual focus is perfectly straightforward, as mentioned above it’s not the most tactile experience.
