Overview

The Sony 1.4x Teleconverter extends focal length by 1.4x with a one-stop light loss, maintaining autofocus and stabilization. Build quality is high, with metal and plastic construction matching compatible lenses and weighing 167-169g. Optical performance depends on the lens; with top lenses like the 100-400mm GM, image quality loss is minimal, but heat haze can cause softness. It suits wildlife photographers needing extra reach without carrying a longer lens.
