Viltrox Teleconverter 2.0X Sony E

The Viltrox Teleconverter 2.0X for Sony E is a 2× telephoto extender that doubles the focal length of compatible Sony E-mount lenses while keeping electronic communication, autofocus, EXIF data, and stabilization support. It’s listed at KSh 37,500 on a Kenyan retailer site, and Viltrox positions it as a compact, dust

and moisture-resistant option for wildlife, sports, and long-reach shooting.

Compatible lenses

Reported compatible lenses include Sony’s 70-200mm f/2.8 GM and GM II, 100-400mm, 200-600mm, 400-800mm, 300mm f/2.8 GM, 400mm f/2.8 GM, and 600mm f/4 GM, plus Viltrox’s 135mm f/1.8.

Optical impact

A 2× teleconverter doubles reach but costs two stops of light, so a 70-200mm f/2.8 becomes roughly 140-400mm f/5.6. The tradeoff is more reach, but a dimmer image and potentially tougher autofocus in low light.

Package and design

The package includes the Viltrox Teleconverter 2.0X Sony E, front and rear caps, and a protective case. Viltrox also says it includes a USB–C port for firmware updates and uses 9 elements in 5 groups, including three high-refractive elements.
