Shopping for a digital single‐lens reflex (DSLR) camera would be stressful. A newcomer to the camera world will be presented with an array of options. It’s hard to keep tracking of the various specifications, models, brand etc. Also, one cannot find “a best digital camera” with all the features incorporated in a single piece. There’s no such thing as a perfect or the best camera. Often, many photographers end up discouraged and even more confused than when they started. Thus, it becomes important to spend a little time considering some basics that may affect the decision‐making process. This paper will take a look at several factors worth taking into account when buying a DSLR camera. In this paper, we will bring in decision making process of selecting the best DSLR camera for a professional. We will apply the Hierarchical decision modeling (HDM) tool proposed by Dr. D. F. Kocaoglu to a simple real life problem. The model breaks down the problem into less complicated smaller segments into a hierarchy. This tool formulates a decision process where either qualitative or quantitative judgments can be measured [1]. Three top rated DSLR cameras are considered and a comparison is made based on the user interested criteria, cost, and features. Our study reveals five different criteria as a base in structuring the decision model. Each of these major criterions is further divided into sub‐criteria based on our team’s judgment as experts in this project. Each of these sub‐criteria contributes as a part of each major criterion’s weight or relative importance. A mini‐survey and pair wise comparison is implemented to measure preferences. The first level of the hierarchy denotes the main objective and the goals are analyzed in the lower levels. Thus our decision hierarchy is represented by tree diagram with goals, criteria and alternatives.
