DG for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. DG lenses provide exceptionally high contrast along with subtle gradations in tone and color. Super Multi-Layer Coating, along with Sigma's optimized optical design work to reduce reflections between the image sensor and the lens surfaces. The large image circles of DG lenses mean there will always be enough peripheral illumination to avoid vignetting.
