Nikon A100 vs Sony A7 Sensor Comparison

More often than not, its hard to imagine the difference between sensor measurements merely by checking technical specs. The visual here might offer you a clearer sense of the sensor sizing in the A100 and A7.

As you have seen, both of these cameras provide different megapixels and different sensor measurements. The A100 because of its tinier sensor is going to make getting shallower depth of field more challenging and the Sony A7 will give you extra detail due to its extra 4MP. Higher resolution will also enable you to crop shots more aggressively. The more recent A100 provides a benefit with regard to sensor innovation.
