The long-awaited sibling for the popular OM-D EM-5 has been announced today. The new OM-D E-M1 comes with some significant changes to both the body design and the interior components. In most cases, these will create a genuine stir among enthusiast photographers, many of whom have invested in Olympus bodies and lenses because of their small size, light weight and superior optical performance. However, owners of the E-M5 may have some reservations about the changes to the user interface.
