Olympus TG-810 vs Sony A7S Sensor Comparison

Quite often, it's hard to visualize the contrast in sensor sizing just by looking through technical specs. The photograph here may offer you a far better sense of the sensor dimensions in the TG-810 and A7S.

As you have seen, both the cameras have got different resolutions and different sensor sizing. The TG-810 using its smaller sensor is going to make shooting shallower DOF more challenging and the Olympus TG-810 will render extra detail with its extra 2 Megapixels. Higher resolution will also make it easier to crop shots much more aggressively. The older TG-810 will be behind in sensor tech.
