Sigma is going to start a new 'Mount Conversion Service' which will enable Sigma to convert the mount of customers’ Sigma Art, Sports and Contemporary lenses.
Interchangeable lens camera systems appear to be superior in offering photographers more options, allowing them to change lenses freely and have more flexible photographic expression. Nevertheless, each interchangeable lens is limited with the specification of different camera systems. In other words, you can’t use those lenses if you change it from one type to another. Although lenses are the key devices to create photographic expression, it is a shame that there is no system that purely sets the standard based on the functions and individual qualities of interchangeable lenses.
In this circumstance, Sigma is going to start the 'Mount Conversion Service' from 2 September 2013. The goal is to provide more freedom for photographers so that customers can select new camera bodies without worrying about the conventional limitation around the mount system of cameras, and keep on using their current lenses by adjusting them to fit with a new mechanism.
