Below is a extended review of the Sigma SD15 vs Sony NEX-3N, one being a Advanced DSLR and the other is a Entry-Level Mirrorless by manufacturers Sigma and Sony.

The SD15 was released 4 years before the NEX-3N and that is a fairly significant gap as far as camera technology is concerned. The two cameras have different body design with the Sigma SD15 being a Mid-size SLR camera and the Sony NEX-3N being a Rangefinder-style mirrorless camera.

Before we go right into a detailed comparison, here is a quick summation of how the SD15 matches up versus the NEX-3N in relation to portability, imaging, features and an overall grade.

More often than not, it is tough to see the difference in sensor measurements merely by researching specs. The visual here should give you a better sense of the sensor measurements in the SD15 and NEX-3N.

As you can plainly see, the two cameras provide the same sensor dimensions but not the same MP. You should expect to see the Sony NEX-3N to render greater detail as a result of its extra 11 Megapixels. Greater resolution can also make it easier to crop pics more aggressively. The older SD15 will be disadvantaged when it comes to sensor technology.
