The 1 was announced 3 years later than the SD1 and that is quite a serious difference as far as technology is concerned. Both of these cameras come with different body type with the Olympus 1 being a SLR-like (bridge) camera and the Sigma SD1 being a Mid-size SLR camera.

Before delving in to a thorough comparison, below is a concise synopsis of how the 1 scores versus the SD1 in regards to portability, imaging, features and an overall grade.

Normally, its tough to imagine the difference between sensor measurements just by checking specs. The graphic here will give you a more clear sense of the sensor measurements in the 1 and SD1.

As you can plainly see, both of the cameras have got different megapixel count and different sensor measurements. The 1 using its tinier sensor is going to make achieving shallow DOF harder and the Sigma SD1 will resolve greater detail with its extra 3MP. Greater resolution will also let you crop images much more aggressively. The younger 1 should have an edge in sensor technology.
