Combined with an exceptionally high sensitivity (F1.8 maximum aperture) this lens offers excellent operational capabilities at a very affordable price in a compact package weighing 1.27kg.
The lens has high MTF over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Relative light distribution is optimized for the more open aperture settings and uniformity of brightness across the image plane combined with the high contrast and excellent picture sharpness produces vividly clear HD pictures. Contrast is extended – flare, veiling glare, and any internal reflections have been substantially reduced. It has tight control of the geometric distortion at wide-angle settings and spectral transmittance characteristic adheres to HDTV colorimetric standards.
Newly developed optical materials combined with the very latest lens element design innovations and multilayer coatings - that produce an unsurpassed pristine imaging system for the most discerning production team.
A Canon design innovation that uses a floating optical system to better control chromatic aberrations.
Enhanced servo system called Shuttle Shot that adds value-added creativity to handheld acquisition systems.
