OM System OM-1 vs Sony A9 II Sensor Comparison
Typically, it's hard to visualize the gap between sensor dimensions purely by checking specifications. The pic below may give you a more clear sense of the sensor measurements in the OM System OM-1 and A9 II.
Plainly, both of these cameras posses different megapixel count and different sensor dimensions. The OM System OM-1 due to its tinier sensor is going to make achieving shallower DOF more challenging and the Sony A9 II will give you greater detail as a result of its extra 4MP. Greater resolution will let you crop pics somewhat more aggressively. The more modern OM System OM-1 should have a benefit in sensor innovation.
