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.

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.

    TelePlus MC4 AF 2.0X DGX Teleconverter for Sony Alpha Digital SLRs is rated 4.0 out of 5 by 6.
    Rated 4 out of 5 by from Limited Use, But Not Bad I've just had this teleconverter for a couple of days, and I have used it with my Tamrom 150-600mm, LAEA3 adapter, and Sony a7rii. I took the attached moon shot yesterday, and am pretty happy with the results. The obvious negative is no AF. And of course a tripod is required. In daylight shots, there is heavy vignetting at 1200mm, and the focus is a little soft. I plan to try it with wildlife, but if they're not sitting still, I don't expect too much. It's a nice tool to have in the bag.

    Rated 4 out of 5 by from Great For The Price I use this to get a bigger range out of my 200mm lens (Minolta 80-200mm f2.8 APO) and it works well.

    Rated 2 out of 5 by from AF does not work properly after 150mm It's really 2x but the statement AF in the product's name is kinda fake. I am not sure if the product is defected or it's just what it is but I'm not happy with this. We tried all the options like CF vs SF etc. I'm using it with Sony Alpha A200 camera and 75-300mm lens.

    Rated 5 out of 5 by from Pretty good It works pretty good for me. I've got the light going through an old Minolta 75-300mm, then the Kenko teleconverter, then a fotodiox adapter, into my Nikon J1, and it all works ok, manually focusing.

    Rated 4 out of 5 by from Practice As with ANY teleconverter,practicing in Manual focus works best. I've tried both the Sony and Minolta 2X converters using focus targets, and can see little difference. Used with 70-200 F 2.8,70-300 G,Sigma 18-300. Will update this review.
