About Viltrox EF-1.4X

For photography enthusiasts and professionals looking to enhance their shooting capabilities, the Viltrox EF 1.4x Extender Teleconverter for Canon EF is an innovative and compact solution. Crafted with high-quality, coated optical glass, this teleconverter is designed to magnify the focal length of your existing Canon EF lenses by 1.4 times, effectively extending your reach without compromising on image clarity.

The Viltrox EF 1.4x Extender is engineered with precision optical design, ensuring that your images retain their sharpness and contrast. Its built-in metal contacts facilitate seamless auto-focus and enable accurate data transmission between the lens, teleconverter, and camera body, maintaining the essential communication for optimal functionality.

This durable teleconverter is particularly well-suited for lenses with a 100mm or longer fixed focal length, such as the 300mm f/2.8 lens, and it pairs exceptionally well with long lenses ranging from 200mm to 500mm. It's the perfect companion for lenses used in wildlife, sports, and portrait photography, where additional reach is paramount.

While the Viltrox EF 1.4x Extender is versatile and can be used with both fixed focus and telephoto lenses, it is not recommended for lenses with a focal length shorter than 60mm, as this may not yield the desired results.

By choosing the Viltrox EF 1.4x Extender Teleconverter, photographers can expand their lens capabilities, achieving closer focusing distances and a wider field of view. It's an affordable and high-quality choice for those looking to elevate their photographic work without the need for additional, costly lenses. Whether capturing distant wildlife or detailed action shots, this teleconverter is an essential tool for photographers aiming to bring their vision closer to reality.
