Panasonic Lumix GH5 review: Autofocus
The GH5 offers 225 AF points spread out across the entire frame, a significant increase on the 49 AF points offered by the GH4.
While the GH5 employs the same DFD (Depth from Defocus) contrast-detect technology of its predecessor, Panasonic claims to have greatly improved the algorithms that underpin it. Combined with the new Venus Engine 10 processor this allows for a claimed focus-acquisition time of just 0.05sec.
Using the camera in ample light, we found autofocus to be all but instantaneous. Performance under artificial indoor lighting also impressed, with the GH5 giving speedy focus acquisition in well-lit interiors.
The orange AF Assist light is impressively powerful, helping the GH5 to make light work of locking on to nearby subjects when required. Switching the AF Assist light off did cause the camera to struggle in really dim conditions. However, the GH5’s AF range is rated down to -4EV, so even then the camera can often acquire focus after some hunting.
Focus mode options include AF-S (Single), AF-C (Continuous), AFF (Flexible) and Manual Focus. Focus Area options, meanwhile, extend to 225-Area, Custom Multi, Single Point, Face/Eye Detection, Tracking and Pinpoint. These are all highly customisable, and again the GH5 makes excellent use of its touchscreen, allowing you not only to move the active AF point/AF zone around the screen, but also expand or retract the size of individual AF points (or zones) via a pinch-to-zoom gesture on the touchscreen.
Overall, the GH5’s AF is both impressively speedy and highly flexible, and we can find no real cause for complaint.
