This macrophoto lens allows expanded photography from life-size to 5x magnification. A floating system using three lens groups has been adopted to deliver high variable magnification in the macro region. It effectively corrects the aberration fluctuation which accompanies changes in magnification. With a UD lens element as the second element, secondary spectrum, a problem during high magnification, is minimized, guaranteeing outstanding imaging performance. The lens is equipped with an EMD (electromagnetic diaphragm) to deliver AE photography*1 Subtle adjustments to magnification are possible using the wide ring. A light-blocking line is incorporated into the front of the lens to reduce inclusion when very close to the subject. It is possible to use the Macro Ring Lite MR-14EX and the Macro Twin Lite MT-24EX. The lens comes with a removable tripod mount which allows smooth switching between vertical and horizontal photography and offers solid support.
*1 AE photography at all magnifications (1x - 5x) is available with the following cameras: EOS-1Ds Mark III, EOS-1Ds Mark II, EOS-1Ds, EOS-1D Mark III, EOS-1D Mark II N, EOS-1D Mark II, EOS-1D, EOS-1V/HS, EOS-1N/DP/HS, EOS-1, EOS-3 (laser matte screen must be replaced). For other EOS models, exposure compensation is required. The actual aperture rises as the magnification goes up, so we recommend using exposure compensation of the Macro Ring Lite MR-14EX or the Macro Twin Lite T-24EX. We recommend using commercially available focusing rails for small focusing adjustments.
