Before heading straight to the technical characteristics of each model, let’s start with comparing their physical specs. Let’s start with looking at the physical difference of the two products. Below are images that clearly show the sizes of Nikon D40 and Pentax K-S2 from the front view.
Now, let’s go on and see how the reviewed models are different or similar by the top view.
After looking at these images, you should get a clear idea of each model’s dimensions and how they are different from each other. However, we are not going to stop there. The next characteristic worth looking at is the weight. Of course, not every photographer is concerned about the weight, for example, it wouldn't be a decisive point for those who shoot in a studio. However, it is still an important factor because if you happen to go on a long photo session or just love having the camera with you wherever you go, you want to be sure that the chosen model isn't too heavy.
Speaking of weight, Nikon D40 is a lighter option of these two, as it weights 156g less than the Pentax K-S2. This difference, in fact, can become a significant disadvantage for the photographers, who prefer to have their cameras with them wherever they go.
Sensor is, without a doubt, the most significant element of every digital camera. Its type, size, and resolution are the factors that define the quality of future shots. Thus, it is barely possible to pick a suitable camera without looking at these specs.
Are Nikon D40 and Pentax K-S2 any different in terms of sensor type?
In fact, that's exactly what makes these two models really different. Thus, it is a good point to consider if your are choosing between these two cameras. Nikon D40 features a 6.0 MP APS-C sized CCD sensor . Pentax K-S2, in its turn, comes with a 20.0 MP APS-C sized CMOS sensor and PRIME MII processor , which makes it significantly different from the first model.
Take a look below to find the comparison of Nikon D40 and Pentax K-S2 by the size of their sensors.
Nikon D40 and Pentax K-S2 are identical by this indicator, as each feature a sensor of the same size. Thus, both cameras will provide the same level of control in terms of the depth of field if you use them with the same focal length and aperture.
If you are interested in photography or has made a career in this field, you should know that different types of shooting actually require different camera characteristics. While one model can produce outstanding portraits, at the same time, it can be terrible for shooting landscapes, and so on. Thus, before you purchase a specific camera, it is vital to decide, which type of shooting you do most often and consider an option that suits it the most.
