Ever since it was first developed, the LUMIX G has continued to improve upon its auto focusing performance.
Contrast AF with DFD Technology*
Panasonic has achieved unprecedented levels of auto focusing precision and speed by incorporating DFD (Depth From Defocus) technology into the already accurate Contrast AF system. Contrast AF with DFD technology attains high-speed auto focusing of 0.07** seconds and enables burst shooting with AF tracking at approximately 7 fps. Being able to accurately follow a moving subject makes for smoother AF video shooting.
*Contrast AF with DFD Technology works only with Panasonic Micro
Four Thirds Lenses.
** In AFS (Auto Focus Single), with H-FS14140 or H-HS12035
LUMIX GH4's Enhanced AF Performance Using DFD Technology
Auto Focus Single
DFD technology achieves high-speed 0.07-sec auto
focusing. The benefits of this improvement grow as the
focal length increases. No more missing those fleeting

High-Speed Burst Shooting
with AF Tracking
DFD technology improves subject tracking performance.
It allows burst shooting at approximately 7 fps, for
accurate focusing on a fast-moving subject.
Smooth Tracking of Moving Subjects
in Videos and Photos
Reduced searching and improved tracking performance provide fast, high-precision focusing even during video shooting.
Engine Processing Isolated from the Sensor Eliminates Image Degradation
The newly advanced engine brings even higher performance to Contract AF with DFD Technology. The distance to the subject is directly measured based on the image captured by the image sensor, so focusing is always accurate. Because this system eliminates the need to use part of the sensor for distance measurement, there is no image degradation. It makes a noticeable difference in video image quality.
AF Technology Supporting High Precision
Accurate Contrast AF
The Contrast AF system searches for the highest contrast condition (the in-focus condition) while the lens is being moved. In other words, focusing is always accurate.
Full-Area Focusing for Flexible Focusing on Any Point
The LUMIX G incorporates full-area focusing to let you focus on any point in the field of
view. You can even focus precisely on the edge of the frame.
Great for Shooting in Dark Places — Low Light AF
The LUMIX G catches all kinds of shooting opportunities, even in dark places. This gains higher performance in -4EV* low-lit situations, which are as dark as a starry sky with no other light source.
* -3EV for the DMC-GH3, G6, GF6.
The focus indicator flashes,
and auto focusing is not possible.
This also lets you take images of children or pets without giving them a shock of AF Assist Lamp.
Great for Shooting Videos
With the LUMIX G, wobbling is fast and fine, so AF is smooth and precise.
A high-speed, silent motor is used in the lens. This prevents the entry of drive noise to achieve high-speed, silent AF.
Versatile AF Mode
The focus detection area is increased from the conventional 23 points to 49 for more flexible composition
Custom Multi AF
Custom Multi mode lets you freely select blocks to focus on from 49 focusing areas.
Face / Eye Detection AF
In addition to the conventional Face Detection AF, the Face/Eye Detection AF automatically focuses on your subject's face or eye.
Seamless 1-area AF
Now the 1-area AF area can be seamlessly magnified not only in manual focus but also in auto focus mode.
Advanced Tracking AF
The camera locks on and automatically "tracks" the subject continuously. New Tracking AF is advanced in the point of tracking accuracy.
More precise auto focusing by further enlarging the focusing area. Display time is selectable.
Selectable Focus Mode
AFF (Auto Focus Flexible)
The focus mode AFF (AF Flexible) locks on the focus when shutter button is half-pressed, however, if the subject moves, the focusing is reset to get the best results.
AFC (Auto Focus Continuous)
The camera automatically focuses on a moving subject.
This is especially convenient when shooting a sports event or when shooting from a moving vehicle.
AFS (Auto Focus Single)
The focus is fixed when the shutter button is pressed halfway. This provides extra convenience when shooting stationary objects or scenery.
MF (Manual Focus)
Manual Focus can be selected when you want to finely adjust the focusing position or when a vintage lens is mounted.
Focus Peaking function shows the peak of focus in MF and AF+MF mode. You can see the focus position while monitoring the subject in live view. It is also available in remote photo / video shooting with smartphone / tablet via Wi-Fi®.*
* Not available for DMC-GH3, GF6, G6.
This function enlarges its magnification range up to 10x in 0.1x steps. In addition to the MF ring control, cursor operation is available.
AF + MF Function
The AF+MF function provides more efficient, more precise focusing. After focusing with AF, simply turn the focus ring manually for even finer control.
