Lightweight, compact and great optical performance tele lens set combined with exclusively designed reducer featuring comparatively short focal length of 200mm but fast aperture f/3.6.
Reducer (7880) reduces focal length from 250mm to 200mm, makes original f/4.5 aperture to brighter f/3.6, helps to improve image quality from corner to corner including coma aberrations and light fall-off performance. Perfect gear to enjoy with full format cameras.
Great performance is achieved by adopting Canon Optron brand fluorite glass element in the optical construction. Exclusive and precise design results in extremely sharp image with less chromatic aberration compared to low dispersion (ED) lenses.
