RELEASED IN 1959, THIS LENS WAS WAY AHEAD OF IT’S TIME. WITH A SINGLE LAYER COATING THAT RENDERS A LOW CONTRAST IMAGE AND BEAUTIFUL FLARES, THIS LENS ALSO HAS SURPRISINGLY LOW CHROMATIC ABERRATION AND MINIMAL FOCUS BREATHING. Reh0used by gl optics, this lens has a 136mm front and a close focus that has been improved from 4’6” to 2’9”. They have also given it a matte finished 15 blade iris for perfectly circular bokeh when stopped down. BEING NICE AND COMPACT, THIS IS A GREAT OPTION FOR HANDHELD ZOOM LENS OPERATING WITHOUT THE SACRIFICE OF CHARACTER.
