I almost always end up using 1-Area for static shots instead of Pinpoint, as I like being able to select a specific point on-screen with my finger and adjust its size according to the size of the subject. The first two are useful for single-point focusing, while the following third, fourth and fifth are more appropriate for groups and moving subjects. Within the AF Mode menu, there are six different options: 1-Area, Pinpoint, 49-Area, Custom Multi, Tracking and Face/Eye Detection. With the G85, I wound up with slightly better results for action than with the GX85, not because the autofocus system is any different but because its SLR-like ergonomics are more comfortable with longer lenses and its large OLED viewfinder makes it easier to follow fast-moving subjects.
Though every situation is different, my hit rate with Lumix cameras featuring DFD technology usually sits between 40-60% if there is enough contrast. The two cameras had far less difficulty following the players, partly because their jerseys stood out against the background but also because they were moving more slowly.
The opposite was true at a women’s soccer match we photographed. The red kites were easier to track against a bright blue sky… …than they were against the brown grass and green trees. I encountered a similar situation at our local red kite sanctuary where the G85 found it less of a challenge to track the reddish-brown birds against the blue sky than when they were against the trees. As soon as the bird touched the water, the G85 lost track of the bird. The G85 managed to track the bird for a few shots while it was against the sky. When the bird was against the sky, the camera had an easier time distinguishing it from the background but as soon as it touched the sea, it began to confuse it with the similarly-coloured waves. A good example is a tern I was tracking with the G85. In scenes lacking contrast, Lumix cameras have the tendency to lose track of the subject, especially if it is fast or moving in an unpredictable fashion.

While the performance is excellent in point-to-point AFS mode, the AFC leaves much to be desired for both stills and video in comparison to the competition.įor slow subjects moving in a predictable fashion, the performance is pretty good for stills on both cameras as you can see from the series of Mathieu running below. Now that all the other mirrorless brands have all switched over to a hybrid autofocus system, Panasonic can be considered the last bastion of contrast detection autofocus. By evaluating two images with different depths of field, DFD calculates the distance to the subject and locks onto it more quickly than standard contrast detection AF systems. It features 49 AF points across the frame. The G85 and GX85 employ the very same Depth from Defocus (DFD) contrast detection autofocus system used on all of Panasonic’s latest models.
