Central to the performance differential is the sensor size and technology each camera employs:

• Olympus XZ-2 iHS: Utilizes a 1/1.7” CMOS sensor measuring 7.44 x 5.58 mm, yielding an effective imaging area of approximately 41.5 mm². Its 12MP pixel count maximizes resolution within physical constraints but inherently limits low-light performance and dynamic range due to smaller pixel pitch and constrained light gathering.

• Panasonic GH1: Employs a larger Four Thirds sized CMOS sensor (18.89 x 14.48 mm), approximately 273.5 mm², representing a considerably increased surface area relative to the Olympus sensor. This translates into superior light absorption, reduced noise at higher ISOs, and better dynamic range performance, critical factors for demanding photographic applications.

Practical implications:

• The GH1’s larger sensor supports cleaner image output at ISO ranges up to 1600 natively (3200 with boost), compared to the XZ-2’s top native ISO of 12,800 - which, while numerically impressive, yields noisier images due to sensor size constraints.
• DxO Mark scores reinforce this: GH1 leads with an overall score of 64 against the XZ-2’s 49, evidencing stronger dynamic range (11.6 vs 11.3), better color depth (21.6 bits vs 20.4) and substantially improved low-light ISO performance (772 vs 216).

Resolution and Detail Rendering

Both cameras output approximately 12 megapixels (~4000x3000 pixels), but the GH1’s photos reveal greater micro-detail and less noise, elevating sharpness in landscape or architectural photography where resolution criticality is paramount.
