Overview

The Kenko Teleplus MC4 AF 2.0 DGX is a 2x teleconverter that doubles focal length while reducing light by 2 f-stops. Optical performance varies: it can introduce softness and chromatic aberration, but with a sharp prime lens, results can be acceptable (OpticalLimits). Build quality is decent with a metal mount, though the plastic barrel feels less robust. Autofocus speed slows significantly, especially in low light. It suits photographers who need extra reach on a budget and are willing to accept some image quality trade-offs.
