Yesterday I reported that Sigma announced something revolutionary, they touted it as “change your mind? – change your [?]“. It turned out that Sigma will start a service to change the mount type of your Sigma lens so you can easily switch system (brand) of your camera without having to sell your old Sigma lenses and buy new ones. Good move by Sigma. They are making outstanding lenses since some time and it makes sense offering such a service to customers. The service is said to be free. The video above shows that it isn’t a too difficult operation to change the mount type of the lens.
Today there are new information about the lens conversion service. The information comes from a slrclub user. All Sigma lenses with 10 contacts can be easily modified to get another mount type, except for Nikon/Pentax version of Sigma lenses. For Nikon/Pentax versions, the aperture will be controlled mechanically after the conversion. There shouldn’t be such issues with Canon/Sony/Other versions of Sigma lenses. Tomorrow we will know more, since Sigma will officially announce the service on August 1st. The service will start from 9/2.
