Nikon D300S vs Sigma SD9

Below, we are looking at the Nikon D300S versus Sigma SD9, both Advanced DSLR digital cameras by competitors Nikon and Sigma. There is a huge difference between the resolutions of the D300S (12MP) and SD9 (3MP) but they feature the exact same sensor dimensions (APS-C).

The D300S was introduced 7 years after the SD9 which is quite a significant gap as far as tech is concerned. Each of these cameras come with the identical body type (Mid-size SLR).

Before diving in to a in-depth comparison, below is a quick introduction of how the D300S scores vs the SD9 when it comes to portability, imaging, features and an overall score.

This is a sample of the gallery pics for Nikon D300S and Sigma SD9. The whole galleries are provided at Nikon D300S Gallery and Sigma SD9 Gallery.

In case you're going to carry around your camera often, you will have to take into account its weight and proportions. The Nikon D300S comes with external dimensions of 147mm x 114mm x 74mm (5.8" x 4.5" x 2.9") accompanied by a weight of 938 grams (2.07 lbs) while the Sigma SD9 has measurements of 152mm x 120mm x 79mm (6.0" x 4.7" x 3.1") along with a weight of 950 grams (2.09 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will change based on the lens you are using at that moment. Underneath is the front view dimensions comparison of the D300S and the SD9.

Taking into consideration size and weight, the portability rating of the D300S and SD9 is 55 and 54 respectively.

Often, it is very difficult to envision the gap between sensor sizes merely by checking technical specs. The image below might give you a more clear sense of the sensor sizes in the D300S and SD9.

As you can tell, the 2 cameras posses the exact same sensor measurements but not the same MP. You should expect to see the Nikon D300S to give greater detail using its extra 9 Megapixels. Greater resolution will also let you crop images somewhat more aggressively. The younger D300S will have an advantage with regard to sensor technology.
