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.
