OM System OM-1 vs Panasonic S1H Sensor Comparison

Typically, it's hard to see the difference between sensor measurements just by reading a spec sheet. The photograph here should give you a more clear sense of the sensor sizes in the OM System OM-1 and S1H.

Clearly, both of these cameras feature different resolutions and different sensor measurements. The OM System OM-1 using its tinier sensor will make shooting shallow DOF trickier and the Panasonic S1H will offer more detail with its extra 4 Megapixels. Higher resolution can also make it easier to crop photographs way more aggressively. The newer OM System OM-1 will have an advantage in sensor innovation.
