Canon 20D vs Sigma SD1

In this write-up, we will be matching up the Canon 20D versus Sigma SD1, both Advanced DSLR digital cameras by manufacturers Canon and Sigma. There exists a substantial gap between the sensor resolutions of the 20D (8MP) and SD1 (15MP) but they use the same exact sensor dimensions (APS-C).

The 20D was unveiled 6 years earlier than the SD1 and that is quite a big difference as far as technology is concerned. Both cameras offer the identical body type (Mid-size SLR).

Before we go through a detailed comparison, below is a concise highlight of how the 20D scores against the SD1 when it comes to portability, imaging, features and an overall grade.

Below is a preview of the gallery images for Canon EOS 20D & Sigma SD1. The full galleries are provided at Canon 20D Gallery & Sigma SD1 Gallery.

For anyone who is planning to lug around your camera frequently, you're going to have to consider its weight and measurements. The Canon 20D features external measurements of 144mm x 106mm x 72mm (5.7" x 4.2" x 2.8") having a weight of 770 grams (1.70 lbs) whilst the Sigma SD1 has proportions of 146mm x 113mm x 80mm (5.7" x 4.4" x 3.1") along with a weight of n/a grams (0.00 lbs).

Bear in mind, the weight of an ILC will change based on the lens you choose at the time. Below is the front view size comparison of the 20D against the SD1.

Looking at dimensions and weight, the portability rating of the 20D and SD1 is 59 and 77 respectively.

Sometimes, it is very hard to visualise the contrast between sensor measurements merely by looking at specs. The photograph below might offer you a far better sense of the sensor sizing in the 20D and SD1.

All in all, each of these cameras enjoy the same exact sensor sizing albeit not the same resolution. You can expect the Sigma SD1 to give you greater detail having an extra 7 Megapixels. Higher resolution can also allow you to crop photographs far more aggressively. The older 20D is going to be disadvantaged when it comes to sensor innovation.
