Sigma launches rewards program for SD1 full-price heroes
Sigma has launched details for their previously promised "rewards program" for the photographer(s) who purchased the SD1 DSLR at full price says dpreview. Besides the price and common sense, another sign that points that the number of SD1 full-price heroes is very small is that Sigma gives the email address of a Sigma representative for eligible photographers to contact. Very rarely companies offer personal one-on-one support :)
But there is proof of at least one photographer using the Sigma SD1, here is the V-Studio photography site.
