Olympus TG-4 vs Sony A7 II Sensor Comparison

          

          

            
Normally, it is very hard to see the gap between sensor measurements only by reading through specs. The graphic below will provide you a stronger sense of the sensor dimensions in the TG-4 and A7 II.
All in all, both the cameras posses different resolutions and different sensor measurements. The TG-4 featuring a tinier sensor will make shooting bokeh harder and the Sony A7 II will give you extra detail as a result of its extra 8MP. Greater resolution can also help you crop images somewhat more aggressively.
