Sigma Tags

These tags are written by Sigma/Foveon cameras. In the early days Sigma was a class leader by releasing their maker note specification to the public, but since then they have deviated from this standard and newer camera models are less than consistent about their metadata formats.

Sigma LensType Values

Decimal values have been added to differentiate lenses which would otherwise have the same LensType, and are used by the Composite LensID tag when attempting to identify the specific lens model.

ValueLensTypeValueLensType
16= Sigma 18-50mm F3.5-5.6 DC 169= Sigma 18-50mm F2.8 EX DC
129= Sigma 14mm F2.8 EX Aspherical 581= Sigma 18-50mm F2.8 EX DC Macro
131= Sigma 17-70mm F2.8-4.5 DC Macro 583= Sigma 17-50mm F2.8 EX DC OS
