Overview

The Vivitar Auto Telephoto 135mm f/2.8, manufactured by Komine (1975-81), offers solid metal build and smooth handling. Its 8-blade iris produces beautiful bokeh, but the 4-element Ernostar design yields a slight romantic softness and lower micro-contrast, with potential glare issues. It excels for close focusing (1:2 magnification) and suits photographers seeking a compact, affordable vintage telephoto for portraits or wildlife, especially on crop sensors.
