Using Panasonic’s Venus Engine, the camera delivers images with smooth tonality, impressive detail, and accurate color reproduction. Notably, it forgoes an anti-aliasing filter, enhancing sharpness at the expense of a slight moiré risk - manageable with modern post-processing.

Resolving 4592 x 3448 pixels, the image files strike an excellent balance of size and clarity. Its native ISO range of 200-25600 (expandable down to 100) provides usable sensitivity for low-light shooting, with clean results up to ISO 3200 in my tests.

Sony HX1: Small Sensor Limits

The HX1’s sensor is a tiny 1/2.4-inch type (6.104 x 4.578mm), 9MP CMOS, yielding a maximum resolution of 3456 x 2592. Its small size restricts light-gathering capabilities, leading to lower dynamic range and higher noise in dim conditions.

Photos shot at base ISO 125 appear decent in good light, but pushing to ISO 800 and beyond introduces noticeable grain and color degradation. The built-in JPEG processing is tuned for punchy colors but lacks the subtlety and sharpness found in larger sensor systems.

Summary: The GX85’s Four Thirds sensor vastly outperforms the HX1’s small sensor in resolution, dynamic range, and noise control, making it the clearer choice for photographers concerned with image quality.

Autofocus and Shooting Performance

Speed and accuracy of focus can make or break critical moments - particularly for wildlife, sports, or street photography.

Panasonic GX85: Reliable Contrast Autofocus with Multiple Modes

The GX85 relies purely on contrast-detection autofocus with 49 focus points covering the frame. While lacking phase-detection, its hybrid system excels in bright conditions and via touch-focus on-screen.

The GX85 offers face detection and eye detection autofocus, which can boost portrait work accuracy. Continuous AF and AF tracking modes ensure dependable performance for slow-moving subjects, although less effective on erratic wildlife compared to phase-detect systems.

Burst shooting caps at 8 frames per second, enabling decent action capture potential.

Sony HX1: Basic AF with Limited Speed

The HX1 uses contrast-detection AF with only 9 points. It lacks face or eye detection and AF tracking modes, which limits usability for dynamic subjects.

Its continuous shooting reaches 10 fps, technically higher than the GX85 but practically hampered by slower focusing and processing bottlenecks, especially in low light.

Summary: The GX85 offers more sophisticated, versatile autofocus features tuned for modern shooting styles, but the HX1’s system suits slower-paced scenarios and simple framing.
