One of the remarkable features of Canon’s HD-EC zoom lenses are the surprisingly small amount of focus breathing, making the lenses ideal for HD-EC production.  The HJ21 has up to 3 times less focus breathing than any other comparable lens, and the HJ11 has an additional 50% less focus breathing. 

Additionally, a maximum relative aperture (T Stop) of 2.1 makes these three lenses faster than ever and the best in the field.  Not only the lens realised to diminish the distortions and the focus breathing into zero level while maintaining the traditional film style feel of the picture, the lens also offers high affordability which will surely lead you to a perfect satisfaction. 

Canon’s HD-EC line now includes the HJ21x7.5B KLL-SC, HJ11x4.7B KLL-SC and HJ8x5.5B KLL-SC zooms and the FJs5, FJs9, FJs14, FJs24, FJs35 and FJs55 primes.  Both utilize Hi-UD (High Index, Ultra Low Dispersion) glass and Fluorite, to achieve lower aberrations, while exhibiting very high MTF. 

The best optical tools in electronic cinematography, HD-EC zoom lenses have been refined using Canon’s exclusive Power Optical System featuring the X-Element, a unique high definition system that combines exceptional performance with enhanced specifications.  All Canon HD-EC lenses have traditional film style feel and operation. Zoom, Focus and Iris indications are engraved with dual large luminous scales(focus distance marked in feet), which have been vastly improved.  Gear rings are compatible with studio focus rigs,manual fluid zoom drives and motorized control systems used for film lenses.
