This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras. Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration.

A molded glass aspherical lens at the rear lens group reduces colour aberration and provides high-quality image results.

"When used on a DSLR with an APS-C sized sensor, the 30mm F1.4 EX DC HSM is equivalent to approx. 52mm."

Why would that be? Wouldn't it be approximately 45mm?

The Canon EOS 20D and 300D have a 1.6x "multipler" factor.

Sorry. I'm a Nikon user, and I believe Nikon's APS-C multiplier is 1.5X.
