Objectives: To compare 5 digital single lens reflex cameras (DSLRs) for extraoral photography in the orthodontic office, to recognize the best camera and the best mode for each camera. Materials and Methods: 5 DSLRs namely Canon 500D, Canon 550D, Nikon D3100, Nikon D40 and Nikon D5000 were compared. Images were clicked in auto mode, program mode, manual mode, macro mode and aperture priority mode. Same settings were used for all cameras. Thirteen orthodontists were asked to rank the images for quality. Data was collected and statistically analyzed using Kruskall Wallis analysis of variance. Results: Canon 500D ranked the highest (P < 0.001) for auto, program and macro mode, closely followed by Canon 550D (P < 0.001), which ranked highest for portrait mode and manual mode. Conclusion: Images by Canon 500D and Canon 550D were perceived better than Nikon for the chosen settings, establishing ease of use for these cameras. This study gives a basic idea regarding technical specifications that can be used for a particular camera for extraoral photography
