As you can see, both cameras provide the same sensor dimensions albeit not the same megapixels. You should expect the Canon 70D to offer you greater detail using its extra 17MP. Higher resolution will also let you crop shots more aggressively. The newer 70D will have an edge when it comes to sensor tech.
