Kenko TELEPLUS HD DGX Teleconverter

This teleconverter is compatible with most Canon EF and EF-S lenses, but it is best suited for prime lenses and telephoto zooms. We recommend checking the specific compatibility list for your lens model, as some wide-angle or specialty lenses may not physically fit or perform well with teleconverters.

You will lose exactly one stop of light. For example, if your lens has a maximum aperture of f/2.8, it will effectively become an f/4 lens when the teleconverter is attached.

Yes, because this model maintains full electronic communication, your camera's autofocus system will continue to function. However, keep in mind that autofocus speed can sometimes slow down slightly, especially in low-light conditions, due to the reduction in the effective aperture.

Yes, the DGX series is specifically designed to pass through all electronic data. Your camera will correctly record the modified focal length and aperture values in the EXIF data of your files.

While any optical element added between the lens and sensor can introduce slight softness, this teleconverter uses high-quality glass and multi-coatings to minimize resolution loss. You will get the best results when using it with high-quality lenses, as the converter will magnify the existing optical characteristics of your glass.

We strongly advise against stacking multiple teleconverters. Doing so significantly degrades image quality, makes autofocus unreliable or impossible, and can physically damage the rear element of your lens or the front element of the converter.
