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 Panasonic Lumix DMC-G7 and Nikon D3100 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, Panasonic Lumix DMC-G7 is a lighter option of these two, as it weights 95g less than the Nikon D3100. 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 Panasonic Lumix DMC-G7 and Nikon D3100 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. Panasonic Lumix DMC-G7 features a 16.0 MP Four Thirds sized CMOS sensor . Nikon D3100, in its turn, comes with a 14.0 MP APS-C sized CMOS sensor , which makes it significantly different from the first model.
Take a look below to find the comparison of Panasonic Lumix DMC-G7 and Nikon D3100 by the size of their sensors.
One more distinctive feature of compared models is the sensor size. Nikon D3100 is equipped with a sensor that is 0.6x larger than the one featured in Panasonic Lumix DMC-G7. Compared to the cameras with smaller sensor area, the ones with larger sensors ensure more control on the blurry background and depth of field if you shoot in the same aperture and focal length. Thus, the first model has a significant advantage here.
