Kenko has launched the Teleplus 1.4x HD DGX and 2.0 HD DGX teleconverters in Canon fit

Kenko has taken wraps off two new teleconverters – the Teleplus 1.4x HD DGX and the Teleplus 2.0 HD DGX T. Initially available in Canon fit and compatible with EF and EF-S lenses, they’re an alternative option to the more expensive Canon EF 1.4x III extender (£314) and the Canon EF 2x III extender (£319). Here we take a closer look at their features and specifications

Teleplus 1.4x HD DGX Teleconverter – £219

The Kenko TELEPLUS HD DGX 1.4X teleconverter will initially be available in Canon fit and contains a set of optics which multiply the focal length of a lens by 1.4x, turning a 300mm lens into the equivalent of 420mm.

The Kenko Teleplus 1.4x HD DGX teleconverter features a 3 elements in 2 groups arrangement

 

Full autofocus operation with the HD DGX 1.4x is possible using a camera lens with an open aperture of f/4 or brighter (except Canon EF 50mm f/1.8). Note that autofocus will only work properly only if there is enough light and contrast on the subject to activate the camera’s AF sensors properly, otherwise manual focusing may be necessary.

Specification:

Magnification: 1.4x
Depth of Field: 1/1.4 of prime lens
Minimum Focus Distance: Same as prime lens
Optical Construction: 3 elements in 2 groups
Diaphragm Coupling: Fully automatic
Exposure Adjustment: 1 Stop
Barrel Length: 25mm
Weight: 110g
Camera/Lens Mount: Canon EF and EF/S

Teleplus HD DGX 2.0 – £279.99

The Kenko TELEPLUS HD DGX 2.0 teleconverter, also initially available in Canon mount, contains a set of optics which multiply the focal length of your prime lens by 2x, turning a 300mm lens into the equivalent of 600mm.

Teleplus HD DGX converters use unique circuitry which maintains signal integrity between the camera body and lens, allowing accurate recording of digital EXIF data. Full AF operation with the HD DGX 2.0x is possible using a camera lens with an open aperture of f/2.8 or brighter (except Canon EF 50mm f/1.8). Like the Teleplus 1.4x HD DGX Teleconverter, autofocus will work if there is enough light and contrast on the subject to activate the camera’s AF sensors.

Specification:

Magnification: 2.0x
Depth of Field: 1/2 of prime lens
Minimum Focus Distance: Same as prime lens
Optical Construction: 5 elements in 3 groups
Diaphragm Coupling: Fully automatic
Exposure Adjustment: 2 Stops
Barrel Length: 35.8mm
Weight: 157g
Camera/Lens Mount: Canon EF and EF/S

    I have the 1.4x Kenko and I do not disable IS but the images are very sharp. Perhaps the advise is to prevent camera shake considering the magnification involved.

    Perhaps this is a bad copy. why not send away for a replacement?

    I have just received the 2x version ans exposure compensation does NOT work. The converter seems to be telling the camera it is two stops smaller than it is and the camera then overcompensates. I get two stops overexposure in all conditions.
    I am a dissatisfied customer.

  • I have just bought the 1.4x version and it works very well with my 100D & 6D using my Canon EF-S 55mm-250mm 4-5.6 STM IS USM lens. Very satisfied with the convertor and higly recommended.

    According to the Kenko website, image stabilisation should be disabled when using these converters, which rather limits their usage. It’s a shame, because Canon’s own converters are not compatible with their 100mm macro lens (it fouls the rear element of the lens, apparently), whereas the Kenko converter fits without any problems. Perhaps Kenko can comment on this, and confirm that image stabilisation must be disabled?
