Lens Technology

ED (Extra-Low Dispersion) Glass

Even with all glass lens construction color failure (non-existent color distortion) is possible because chromatic aberration cannot be completely removed in relation to focal length.

To overcome this, extra-low dispersion (ED) glass lenses have been specially designed which deliver a large dispersion ratio for a specific short wavelength zone.

By installing ED glass lenses into the lens units, chromatic aberration is significantly reduced, achieving images with clear color reproduction, high sharpness and high contrast.

FUJIFILM has developed specific technology for the accurate production of large diameter ED glass lenses used in FUJINON broadcast lenses. This technology has been used in the production of XF lenses.
