Photography is an art that many pursue either as a hobby or as a profession. The first step to mastering photography is choosing the right camera. This project focuses on a decision-making tool to guide beginner photographers in the factors that must be considered while buying a digital camera, focusing on some popular and top entry-level digital cameras in the market. This project uses a 3 level Hierarchical Decision Model (HDM) with five selection criteria – configuration, features, dimensions and price which are further divided into 12 different sub-criteria. There were 5 different entry level digital cameras considered in the study. Judgement from 8 different experts from 3 different skill levels was obtained to be utilized in the HDM tool. The study concluded that price and configuration of the camera were the main features to be considered while purchasing an entry-level camera and even though all the models had equal weights, the Sony Alpha A6000 mirrorless camera stood out among them. This study does not include a comprehensive list of criteria, omitting some features of the camera that could be considered in a future study. Additionally, this study ignores lens comparison as a criteria to avoid complexity which could be addressed in a future study.
