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 is rated 4.0 out of 5 by 19.
    Rated 5 out of 5 by from I would buy this product again and again I have this tele-converter on a nikkor af-s 18-200mm 3.5-5.6 primarily for now. The auto focus does work but you need a good amount of light. The camera records the correct aperture and focal length. I would buy again and recommend to a friend.

    Rated 4 out of 5 by from Very Good I bought this teleconverter after doing extensive research and being fully aware there may autofocus issues especially in low light situations. My primary use for this TC is for lunar, solar, and eclipse photography. With that being said, I would be using manual settings and focus anyway with my camera on a nice sturdy tripod. This TC is absolutely perfect for my needs and have been very pleased with it thus far. I have no issues with and it does what it's supposed. If you master your camera settings and focus you will get very sharp images...or at least I have thus far. Might even upgrade to MC7 in the future. I only gave it a 4 star rating because nothing is 100% perfect but I am very happy and pleased with this TC and would highly recommend it!! For those who may be interested, I use this on a Nikon D3300 DSLR paired with the Nikkor AF-P DX 70-300mmG f4.5-6.3 ED non VR zoom lens!

    Rated 5 out of 5 by from Good Improvement I wanted a converter in order to improve the detail in my photographs of birds. The 2 x converter allowed me to get better images provided I use my tripod. My next step (it never seems to end) is to purchase a more stable tripod in order to improve the sharpness of the photographs. Since I was warned in the B&H reviews of the converter that the focus would be manual only I was not surprised that the autofocus did not work. I did not hear any grinding sounds as some reviewers have commented.

    Rated 5 out of 5 by from I would buy this product again! ...Wow! What a difference it makes with my 70-200 Zoom. I love the 400mm. The photos are still excellent. They are very clear with no hint of distortion or color inaccuracy. This teleconverter's quality is competitive the name brands at a much lower price. It didn't take me long to learn that the 400mm setting requires a steady hand. The VR work quite well at 400mm but you have to concentrate on keeping the camera steady. It would probably be wise to use a tripod.

    Rated 2 out of 5 by from way too soft it will make the subject more magnified, but you lose so much quality I feel the extra zoom is not worth the price. Most subjects you shoot at the higher zoom will be wildlife. they don't stay still for a good shot. consistant softness at all ranges with my 70-200 L lens tells me that it is better to shoot without the convertor and crop on the computer. I will spend more money on my next teleconvertor and hopefully get the quality I am looking for.

    Rated 5 out of 5 by from I would buy this product again ... I was finally able to carry it out and play with it. It is attached to my 70-200 Zoom. Wow! What a difference between 200mm and 400mm. The pictures are still crisp and clear. I see no deteriation in the quality. I learned in a hurry that 400mm requires a steady hand. You will probably do a lot better with a tripod.
