Clearly, the two cameras provide the same sensor dimensions but not the same resolution. You should expect to see the Sony A77 II to give you more detail having its extra 19 Megapixels. Greater resolution will allow you to crop photos more aggressively. The older SD15 is going to be disadvantaged when it comes to sensor tech.
