Sigma 30mm F1.4 EX DC HSM A - Canon EOS

This is a fast F1.4 aperture standard lens for digital cameras. SLD (Special Low Dispersion and ELD (Extraordinary Low Dispersion) glass elements are used to obtain the best possible correction for magnification and chromatic aberrations, which are particular problems for digital cameras. 

From 40cm (15.7”) minimum focusing distance to infinity, this lens creates very sharp images with high contrast. The HSM models provide quiet, high-speed auto-focus shooting, as well as full-time manual focus override. Large maximum aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.
