EX Lens - With uncompromised design ideas and high-level optical technology and handling, these lenses, which are Sigma's representative lenses, meet the requirements of photographers at the highest level.
DG Lens - These are high-performance lenses optimized for digital cameras. They are ideal not only for 35 mm digital SLR cameras and film SLR cameras but also for APS-C digital SLR cameras. They deliver superior image quality by correcting for all types of aberration, especially distortion, and they have high resolution capability because they minimize chromatic aberration of magnification, which is particularly a problem for digital cameras. What is more, these lenses incorporate optical designs optimized for digital cameras and Sigma's own Super Multi-Layer Coating technology, so they reduce flare and ghosting due to reflection between the image sensor and lens surfaces, and they provide high contrast and a wide range of tone. They also provide enough peripheral brightness with little vignetting.
