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 D750 and Pentax 645Z 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 D750 is a lighter option of these two, as it weights 710g less than the Pentax 645Z. 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 D750 and Pentax 645Z 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 D750 features a 24.0 MP Full frame sized CMOS sensor . Pentax 645Z, in its turn, comes with a 51.0 MP Medium format sized CMOS sensor and PRIME III processor , which makes it significantly different from the first model.
Take a look below to find the comparison of Nikon D750 and Pentax 645Z by the size of their sensors.
One more distinctive feature of compared models is the sensor size. Pentax 645Z is equipped with a sensor that is 0.6x larger than the one featured in Nikon D750. 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.
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.
