HC-X2 vs ZV-1F

Sensor size dwarfs almost every other camera spec for image quality.

Common sizes (smallest to largest)

• 1/2.5" – 1/1.3" — smartphone sensors. Area: 24–58 mm².
• 1" — premium compacts, top phones (Xiaomi 14 Ultra). 116 mm².
• Four Thirds — Panasonic, OM System. 225 mm².
• APS-C — Sony, Fujifilm, Canon mid-tier. 332–370 mm².
• Full Frame (35 mm) — 864 mm².
• Medium Format — Fujifilm GFX, Hasselblad. 1,452 mm².

Practical effect

Each step up roughly doubles light capture. A full-frame at ISO 6400 looks like an APS-C at ISO 3200 or a Four Thirds at ISO 1600.

Depth of field

Larger sensors give shallower DoF at equivalent framing — the "creamy bokeh" look. Phones simulate this computationally; results vary.
