Key Features

1. Genuine Gate Array IC

The HD DGX 1.4X converter is equipped with a genuine Gate Array IC, which ensures that the signal integrity between your camera body and lens is maintained. This advanced circuitry allows for seamless communication and autofocus operation.

2. High-Quality Optics

The converter features a 3 5-element design made with high-quality multi-coated optical glass supplied by Hoya Corporation, the world’s largest manufacturer of optical glass. This ensures that your images are sharp, clear, and free from any unwanted distortions or aberrations.

3. Full AF Operation

The TELEPLUS HD DGX 1.4X converter allows for full autofocus operation when used with a camera lens that has an open aperture of F4 or brighter. However, it is important to note that sufficient light and contrast are necessary for the camera’s autofocus sensors to function properly. In low-light situations, manual focusing may be required.

4. Updated Circuitry

The TELEPLUS HD DGX converters have updated circuitry that accurately records exit data in the exit exposure data (meta-data) of your digital pictures. This includes the equivalent aperture and focal length of the lens setting plus teleconverter. The improved circuitry ensures precise and reliable data recording.


Q: Can I use the converter with lenses that have a smaller open f-stop value than F4?

A: When using lenses with smaller open f-stop values, manual focusing may be necessary as autofocus may not work properly. It is recommended to use lenses with an open aperture of F4 or brighter for full AF operation.

Q: How does the HD DGX 1.4X converter compare to previous models?

A: The HD DGX 1.4X converter offers significant improvements in lens performance, especially in terms of resolution. Compared to the MC4 and MC7 models, the HD DGX 1.4X converter provides a 150% increase in resolution, resulting in sharper and more detailed images.
