Oftentimes, it can be difficult to envision the gap in sensor sizing merely by researching technical specs. The graphic below will help offer you a more clear sense of the sensor sizes in the 70D and A850.

As you have seen, both the cameras provide different megapixel count and different sensor sizing. The 70D using its smaller sensor will make shooting shallow DOF tougher and the Sony A850 will result in extra detail because of its extra 5MP. Higher resolution will help you crop photographs more aggressively. The more modern 70D is going to have an edge in sensor technology.
