SUMMARY
The Viltrox TC 2.0 is the first third-party 2x teleconverter for Sony E-mount, offering a $280 alternative to Sony's $600 version. This teleconverter doubles a lens's focal length and magnification without altering minimum focus distance, enabling 1:1 macro with certain lenses. Despite a two-stop light loss, it provides solid autofocus performance and good build quality with weather sealing and a USB-C port for firmware updates. Notably, it works with Viltrox and some Sigma lenses, expanding compatibility beyond Sony's own offerings, though potential licensing issues are a consideration.
