Olympus TG-830 iHS vs Sony A77 Sensor Comparison

		

		

			
Normally, it is very hard to see the contrast in sensor dimensions simply by viewing a spec sheet. The image below might give you a greater sense of the sensor measurements in the TG-830 iHS and A77.
As you can see, each of the cameras provide different resolutions and different sensor dimensions. The TG-830 iHS due to its smaller sensor will make shooting shallower DOF more difficult and the Sony A77 will result in more detail having its extra 8 Megapixels. Greater resolution will let you crop images more aggressively. The more recent TG-830 iHS will have a benefit when it comes to sensor technology.
