New High Speed lenses by Sigma, based on the famous Sigma Art photo lenses, but now in a completely redesigned housing. Lightweight and compact, in a sealed housing to prevent dust and moisture from entering. All lenses have standardized gear positions for easy lens changes. The lenses are compatible with full frame and S35 sensors, and offer 8K resolution. The lineup ranges from 20mm to 85mm, all T1.5. In the near future a 14mm and 135mm T2.0 will complete the range
