Olympus TG-310 vs Sony A77 II Sensor Comparison

In many cases, it is difficult to imagine the gap between sensor dimensions simply by checking specifications. The pic below will help provide you a better sense of the sensor dimensions in the TG-310 and A77 II.

Plainly, both the cameras enjoy different resolutions and different sensor dimensions. The TG-310 due to its tinier sensor is going to make achieving shallow depth of field more challenging and the Sony A77 II will resolve extra detail as a result of its extra 10MP. Greater resolution can also enable you to crop images far more aggressively. The more aged TG-310 is going to be disadvantaged when it comes to sensor technology.
