About Kenko MC7 AF 2.0X DGX

Placed between the camera body and lens, a teleconverter contains a set of optics that will effectively increase the focal length of any lens with which it is used. The Kenko TelePlus MC7 AF 2.0X DGX converter has the effect of multiplying the focal length of your lens by 2.0x, turning a 300mm lens into an equivalent 600mm lens. The MC7 AF 2.0X DGX converter has genuine Gate Array IC (Integrated Circuitry). It means the converter's unique circuitry maintains signal integrity between the camera body and lens.

The 7-element design is made with high quality multi-coated optical glass supplied by Hoya Corporation, the world's largest manufacturer of optical glass. Full AF operation with the TelePlus MC7 AF 2.0X is possible using camera lenses with open apertures of F2.8 or brighter. AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. (Manual focusing may be necessary when using lenses with smaller open f-stop values than that 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.

The Kenko MC7 AF 2.0X DGX is commonly used for Wildlife photos and more.One reason why the Kenko MC7 AF 2.0X DGX is popular is because of its Easily interchangeable

Great Product at a Terrific Price

Eh, you get what you pay for


from Los Angeles CA  -  Photo Enthusiast

It drastically reduces your f-stop. It's buggy, especially with my older 50mm. Will not allow my newer Nikon 105mm VR autofocus.


Did what I wanted


from Hattiesburg, MS  -  Photo Enthusiast

I was told it would not work with my Tamron 18-270 lens but it works just fine. Of course it needs support for the camera at long telephoto but this is to be expected. I was surprised at how well the autofocus worked.


Kenko Teleplus 2x


from North Carolina  -  Photo Enthusiast

Just received it 2 weeks ago and have not had much time to test it. However, I took a few pictures at a familiar location and it performed as expected. I am happy with the product.


A good choice for my needs


from Pennsylvania  -  Photo Enthusiast

I was looking to get a bit more zoom out of my 200 mm lens and this did the trick . For the money it is a good lens.


Works great


from Philippines  -  Casual Photographer

Works very good.


Adequate for the job


from Flagstaff, AZ  -  Semi-pro Photographer

Used to take pictures of a solar eclipse, the fact that the auto focus would not work with the standard canon EF lenses was disappointing. Having to manually focus the lens can be difficult, but it behaved as expected. I used it attached to a 80-200 mm zoom lens. I am happy with the final output. Image quality did not seem to suffer. I would not use this for fast action or low light when used with a long lens.

In answer to many questions


from Along the Frontrange, CO  -  Photo Enthusiast

Since I bought mine I get emails from Adorama asking for feedback to specific info requests, but the link provided doesn't get me to those requests, just to the overall product page. And since I can't reply to the email from Adorama itself, the whole thing "ask a question and a knowlegeable customer will reply" thing is a bit of a joke. I'm using this item with a Sigma 150-500, itself not the sharpest of lenses (but ok for the price), and with the converter I can't expect tack-sharp pix. Manual focus only, so BIF etc. are tough to shoot. Static objects are best, on tripod with remote release of course. Hope this helps. Recommended within the obvious limitations - don't expect the world.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
DAVID A  I purchased this teleconverter to give me more long lens options, particularly in photographing birds. I haven't used it much yet, but I recently bought a 70-300 telephoto lens and hope to make use of the teleconvertor to bring birds closer in the photo.
Ronald S  : I have a canon t3i with a canon 70-300 zoom lens will this work with it?
CARL P  IF that lens is an EF, it will work. If that lens is a EF-S, it will NOT fit/lock into the adapter.. Also, if that lens is f/3.5 or slower, The doubler won't work well, you need a f/2.8 or stated in the description.....or, go to manual focus/live view.......
JOHN M  Is this teleconverter compatible with a Canon ES 6D using a Canon EF 24 - 105 mm L f/4 lens?
RAY P  John M, I found that the picture quality dropped off just enough that I stopped using teleconverters--even the 1.4.
JOHN M  Hi Ray, Thanks for your reply and opinion about teleconverters. Just one question: what lens (lenses) did you use with the teleconverter? Thanks, John M
