Sigma launch mount switching service
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 from one camera fitting to another.
The ranges convertible include the new Sports models such as the 120-300mm f/2.8
“We believe that a lens is not only such a key device for photographic expression, but also an important resource for photographers”, they say. “It has been our hope to develop the lens system that is genuinely photographer-centered, and you can enjoy it for a longer period of time. As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, our desire and know-how is crystalized in this unique service. With this service, the mount of your SIGMA lenses can be converted to another mount system, depending on the specification of camera bodies. This service will be available from September, 2013.”
Editor’s comment – this feature of the new Sigma lens designs was not even mentioned at photokina 2012. They have kept something under wraps which must have been planned from a very early date. The main lens unit of all Sigmas in these series has to be effectively independent of the mount, with electronic protocol conversion chips to handle aperture and focus operation while different rear assemblies change the bayonet.
“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”, states the Sigma release. “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 2nd September 2013. Our goal is to provide more freedom for photographers so that they 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.”
