Both Canon and Fujinon 2/3" professional lenses offer near broadcast optical performance and quality. 2/3" professional lenses are internal focusing, have optional range extenders and can accommodate servo zoom and manual focus remote controllers.
Professional Lenses
Internal focusing reduces the lateral chromatic aberrations and improves corner performance. Square hoods are now utilised in all 2/3" professional lenses in place of conventional circular hoods due to the non rotation of the front barrel in all IF lenses. Square hoods reduce flare and ghosting.
