Sigma 30mm f/1.4 EX DC HSM for Canon
Because the Sigma 30mm f/1.4 EX DC HSM for Canon is specifically designed for digital SLR cameras, this focal length of 30mm translates approximately to 50mm in 35mm format, making it the most similar to the human eye. A glass mold aspherical lens element at the rear group of the lens reduces color aberration and provides high-quality image results. From 15.7" to infinity, this lens creates very sharp images with high contrast, and can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting, and landscape photography.
This lens is recommended only for the crop-frame cameras (20D, 30D, 40D, 50D, 60D, 7D, Digital Rebel series, etc. digital cameras). It is not recommended for use with the 1D or 5D series digital cameras nor 35mm film cameras because vignetting will occur.
