You have probably seen professional photographers in certain genres (weddings, for example) shooting with two camera bodies simultaneously. Why do they do this and what are the benefits of carrying that extra weight? This excellent video discusses the topic and offers some tips for working with two cameras simultaneously.
Coming to you from David Bergman with Adorama TV, this great video discusses why photographers sometimes shoot with two cameras simultaneously and offers some helpful tips for doing so. For the most part, photographers will use two bodies when they are in demanding and quickly evolving situations that also require a wide range of focal length coverage or when they want a utilitarian lens (like a 24-70mm) paired with a more creative one (like a wide 50mm). For example, when I shoot classical music concerts, I can't make noise or waste time by changing lenses in the middle of the piece, so I shoot with two bodies, one with a 400mm f/2.8 for nice closeups of single performers and the other with a 70-200mm for wider shots of entire ensembles. It can make your life a lot easier once you get used to handling two cameras at a time. Check out the video above for the full rundown from Bergman.
