Autofocus (AF) systems are vital for nearly all photographic genres, especially motion and wildlife.

The GH2 uses an older contrast-detection AF, making it slower and more prone to hunting under challenging conditions, especially in low light or fast action.

The A6300 integrates 425 phase-detection points covering nearly the entire frame, paired with contrast detection. This hybrid system delivers quick, precise focus, even on moving subjects. In practice, I found the A6300 locks focus almost instantly and tracks subjects reliably - key for sports and wildlife photography.

Image Stabilization: Is There Support In-Camera?

Neither the Panasonic GH2 nor Sony A6300 offers in-body image stabilization (IBIS). Stabilization depends on lens technology: Panasonic’s Micro Four Thirds system has lenses with optical image stabilization (OIS), and Sony’s E-mount lenses may have OSS (Optical SteadyShot).

For handheld shooting, especially in low light or macro, the effectiveness depends heavily on your lens choice rather than the camera bodies themselves.
