Macro photography is normally considered an expensive and complicated part of photography. Specialised lenses, difficult techniques and a required attention to detail that is only beaten by expert landscape photographers, the capturing of the small could be seen as a large challenge.
It doesn't need to be this way. Anyone with a Canon dSLR can buy a M42 lens on the cheap, grab some M42 extension tubes, and add an EF-M42 lens mount adapter and you'll be good to go. Be adventurous, shoot hand-held with flash, and try plenty of different angles. Sure, you'll get loads of out of focus blurry shots, but one in twenty will be good, and you will surprise yourself.
