The 7D was released 10 months earlier than the SD1 which means that they are both of a similar generation. Both of these cameras come with the identical body type (Mid-size SLR).

Before we go straight into a step-by-step comparison, below is a quick summation of how the 7D scores versus the SD1 in regards to portability, imaging, features and an overall rating.

Below is a sample of the gallery pics for Canon EOS 7D and Sigma SD1. The complete galleries are available at Canon 7D Gallery and Sigma SD1 Gallery.

Generally, it can be difficult to envision the difference between sensor sizing just by reading specifications. The photograph underneath will help provide you a much better sense of the sensor sizes in the 7D and SD1.

To sum up, the 2 cameras have got the exact same sensor measurements but not the same resolution. You should expect to see the Canon 7D to offer you extra detail as a result of its extra 3 Megapixels. Greater resolution will also let you crop images much more aggressively. The older 7D is going to be behind in sensor innovation.
