Technical

THIS 14 INCH LENS WAS KARSH'S FAVOURITE, AND THE ONE HE USED MOST OFTEN. (REF. 2) IT IS AN EARLY "COMMERCIAL EKTAR", ADVERTISED BY KODAK AS COVERING ADEQUATELY 8X10 INCH NEGATIVES AT MAXIMUM APERTURE WITH ALLOWANCE FOR FULL USE OF RISING & FALLING FRONT, AND SWING BACK. "LUMINIZED" SURFACE TREATMENT IMPROVED CLARITY & BRILLIANCE IN B&W NEGS, AND COLOUR PURITY IN COLOUR TRANSPARENCIES. (REF.1).
