Sigma is announcing that you can now (on selected lenses*) have them convert all Sigma Global Vision lenses to your syste, whether it be Pentax, Sony, Canon, Nikon ...
See this here:
Change Your Mount | Sigma
and they will also offer a "new" extended warranty for 4 years in the USA.
(I believe that the Canadian warranty on some selected lenses will stay at 10 years though).
As it is mentioned: this is a
paid service, regardless of the warranty type.
Anyway, this may come handy for those who buy one of the "selected" lenses and decide later on to switch system and still be able to use it on their new gear after Sigma converts the lens(es).
Note: I have no financial reason to post this ... just for the information which I thought was very interesting.
