Kenko MC4-AF2.0DGX-C overview

  • 1Description

The Kenko TelePlus MC4 AF 2.0X DGX Teleconverter (also known as a tele-extender) gives you the dramatic effect of doubling the focal length of your lens by 2x, and will cut back the amount of light by 4x (2 f/stops). The MC4 features a 4-element, 4-group design with multi-coated lens elements, and fully automatic diaphragm coupling. With the Kenko TelePlus MC4 DGX your prime lens' depth of field is reduced by 1/2, but retains the prime minimum focusing distance. Using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6.

The MC4 AF 2.0X DGX converter has genuine Gated Array IC (Integrated Circuitry). This means that not only the converter's own unique data but all data sent from the camera body provides full exposure metering and linkage for electronic flash photography.

Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.

Note: NOT for use with Canon EOS EF-S lenses

The DGX TelePlus converters have updated circuitry to record exif data more accurately. In the exif exposure data (meta-data recorded with a digital picture) DGX converters record the equivalent aperture and focal length of the lens setting plus teleconverter. Optically and mechanically they are identical to the prior high-quality DG series converters.

    Kenko MC4-AF2.0DGX-C reviews

    TelePlus MC4 AF 2.0X DGX Teleconverter is rated 3.4 out of 5 by 7.
    Rated 4 out of 5 by from Autofocus Works I first got the the 1.4x but it didn't give me enough reach and tend to over-expose so I returned it. Also get to try the 3x while at the store. The auto-focus was too slow with the 3x so i settled with the 2x. Used a T2i & Canon 70-200mm IS F4, auto-focus was fast enough to capture some sharp images of my cats but it does hunt a little when used indoor. For the first time, I also managed to get some good details of the moon. My only complaint is that the mount and lock is a little loose, feels like i could push it by mistake and the lens will drop out if not careful.

    Rated 4 out of 5 by from Quality product and performance I use this with my 5D2 and my 7D. Auto Focus was very quick using my 5D2/7D with the 70-200 2.8IS with good IQ. AF wasn't so quick when used with my 100-400.

    Rated 3 out of 5 by from Yes and No It was good on static shots but shooting sports not as good.

    Rated 4 out of 5 by from Exactly the product I needed!! So cannon doesn't make anything to fit my 2yr old camera... but Kenko does... This was just exactly what I wanted and needed. The quality is worth 5 stars... unfortunatly I wish the auto focus worked better with it.
    Date published: 2012-02-06
    Rated 4 out of 5 by from Good Quality & Great Price I Used T2i & Tamron SP 90mm f/2.8 Macro, auto-focus was fast enough to capture sharp images. The genuine Gated Array IC (Integrated Circuitry) was good enough to sent data from the camera body provides full exposure metering.
    Date published: 2011-02-09
    Rated 4 out of 5 by from It's like standing next to your subject recommended to me by B&H customer service to use with a 300mm sigma lens. I use manual focus when in 300mm mode Works great Purchased a 500mm sigma and autofocus works but it's easier to use manual at 500mm mode At 400mm or below the autofocus works fine. Picture quality is good
    Date published: 2013-04-19
    Rated 1 out of 5 by from inacceptable The quality of this converter is unuseable. Center is halfway blurry, outer area totally blurred.
