Sigma believes that a digital SLR camera should empower the photographer in two distinct stages: during image creation and during image processing. Photographers should have all of the resources necessary to recreate the ideal image retained in the mind’s eye.
For this reason, the SD15 offers photographers the highest-quality data that is ready for professional finishing, broad in dynamic range and rich in harmony and color. For use in RAW mode in all of its cameras, Sigma has developed the .x3f format to capture the pure, rich data that a true full-color sensor has to offer.
Just as the best ingredients help create a gourmet dish, the finest data helps the photographer express individual skill and vision. RAW data in the .x3f format is what photographers require to do the very best work that only they can do.
