The Viltrox 2X Teleconverter for Sony E mount is an accessory that fits between the camera and the telephoto lens to double the focal length of the setup. With it, a 70-200 mm becomes a 140-400 mm and a 200-600 mm reaches 1200 mm, extending the range for wildlife, sports, and distant subject photography without changing lenses. It features an intelligent chip with full EXIF transmission and fast, accurate phase-detection autofocus. Its optical formula of 9 elements in 5 groups, including 3 high-refractive (HR) elements, maintains excellent resolution in a compact, weather-sealed body weighing only 225 g.

Is the Viltrox Teleconverter 2X the right accessory for you?

It's the ideal choice if you shoot with Sony E-series telephoto lenses and need more reach in specific situations without carrying an extra lens. Doubling the focal length takes you from a 200-600mm to a 1200mm equivalent, a decisive advantage in bird, wildlife, sports, and aviation photography, where getting close to the subject isn't always possible. Its native integration maintains fast autofocus and EXIF data, so you can continue working as usual.

When to consider it: 2x magnification reduces brightness by two stops, so it performs best with fast telephoto lenses and in good light. If your priority is maximum aperture or you often work in low light, also consider a teleconverter with a lower factor or a prime lens. For gaining reach in a compact and affordable way, 2x magnification is a very effective solution.

Galaxy Andorra's opinion

The Viltrox 2X Teleconverter is a smart way to extend the reach of a Sony E-mount camera without investing in a new super-telephoto lens. Its native integration preserves fast autofocus, EXIF data transmission, and 120fps burst shooting, while the optical formula with HR glass maintains a very convincing level of detail. For wildlife, bird, or sports photography, where doubling the focal length makes all the difference, it's a fully justified and highly versatile investment. At Galaxy Andorra, we recommend it to those who already own a good Sony telephoto lens and want to maximize its reach with a compact and well-built accessory.

Frequently Asked Questions

What exactly does a 2X teleconverter do?

It mounts between the camera and the telephoto lens and doubles the focal length of the combination. For example, a 200-600mm lens then behaves like a 400-1200mm lens, significantly bringing distant subjects closer.

What goals is it compatible with?

It's optimized for a selection of Sony E-type telephoto lenses and the Viltrox 135mm F1.8 LAB FE. The compatibility list expands via firmware updates, so it's a good idea to keep it up to date.

Does it lose brightness when I use it?

Yes. The 2x magnification reduces brightness by 2 stops: an F2.8 lens behaves like an F5.6. That's why it performs better with fast telephoto lenses and in good lighting conditions.

Does it retain autofocus and EXIF data?

Yes. The built-in smart chip retains phase-detection autofocus, eye tracking, and full EXIF transmission, with burst shooting up to 120 fps on compatible bodies.

Does stabilization work with the converter installed?

Yes. It correctly transmits focal length data so that the camera's IBIS stabilization and the lens's OSS work together, helping to achieve sharp handheld shots at very long focal lengths.

Can the firmware be updated?

Yes. It has a USB-C port that allows you to connect the teleconverter to your computer and apply Viltrox firmware updates, which add compatibility and performance improvements.
