Are you looking for the best camera to suit your needs? Due to a wide range of options, making a wise and weighted decision can be rather challenging. Which specs to keep in mind? What are the key pros and cons of each model? This comparison should give some helpful hints!
The goal of this overview is to provide a detailed comparison of two popular camera models from Pro DSLR category, introduced by Pentax. We are going to take a closer look at the technical and physical characteristics, features, and performance. The models we are going to assess and compare in this review are 645D and 645Z. The models we are going to compare in our review have different sensors. Pentax 645D features a CCD sensor that has a resolution of 40.0 MP. Pentax 645Z, on the contrary, has a different CMOS sensor with 40.0 MP resolution.

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 Pentax 645D 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, Pentax 645D is a lighter option of these two, as it weights 70g 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 Pentax 645D 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. Pentax 645D features a 40.0 MP Medium format sized CCD sensor and boasts of a Prime II processor . 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 Pentax 645D and Pentax 645Z by the size of their sensors.
Pentax 645D and Pentax 645Z 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.
This section of our comparison is devoted to the performance of Pentax 645D and Pentax 645Z in different fields of photography. Here we are going to look at the five main areas and evaluate how well each of the reviewed models performs in them. This will help you choose an option that suits your needs the most depending on your interest in one or several of these fields.
