The TG-870 was introduced 5 years later than the A390 and that is a fairly large difference as far as camera technology is concerned. Each of these cameras feature different body design with the Olympus TG-870 being a Ultracompact camera and the Sony A390 being a Compact SLR camera.

Before getting right into a in depth comparison, here is a brief synopsis of how the TG-870 matches up versus the A390 in the way of portability, imaging, features and an overall grade.

Typically, its difficult to visualize the contrast in sensor measurements purely by seeing specifications. The photograph here may give you a more clear sense of the sensor sizes in the TG-870 and A390.

Plainly, both of those cameras feature different megapixel count and different sensor measurements. The TG-870 using its smaller sensor is going to make achieving shallow DOF harder and the Olympus TG-870 will provide extra detail using its extra 2MP. Higher resolution will also make it easier to crop pictures way more aggressively. The younger TG-870 provides an advantage in sensor technology.
