Overview

The Kenko Teleplus Pro 300 AF 1.4x is a budget-friendly teleconverter that extends focal length by 1.4x while maintaining autofocus and electronic communication with compatible lenses. Optical quality is decent but shows slight sharpness loss, as expected. Build quality is good but not as tight as proprietary converters, and it lacks weather sealing. It suits photographers needing occasional extra reach without investing in a new lens, especially those with lenses incompatible with brand teleconverters.
