About Kenko MC7 AF 2.0X DGX

Kenko MC7 AF 2x Teleplus converter gives you the dramatic effect of doubling the focal length. KENKO AF Teleplus converters have genuine Gated Array IC. This means that not only the converters own data but all data sent from the camera body provide full exposure metering and electronic flash photography. Auto focus is retained with lens that have a maximum aperture of F/4 or brighter. (Manual focusing will be required with lenses of smaller aperture)

Did what I wanted

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.

Eh, you get what you pay for


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

Kenko Teleplus 2x


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


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


Works very good.


Adequate for the job


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


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:

SCOTT N  Not sure. I have DSLR-A700 and SLT-A77 and the electronic functions are not reliable when used with either one. The camera usually doesn't recognize the reduced lens speed and then the autofucus doesn't work. I've tried all combinations of powering on and connecting lenses and can't find a sequence that works every time. Returned the first lens and the second was the same. It's a great lens for manual focus as the images are real sharp. I wish they would fix it because the sony 2x converter won't work with my sigma and tamron lenses. The glass interferes preventing a mating of the converter.
Tim B  I have a Sony A390 DSLR. Will this teleconverter work that camera? Thanks in advance for the help.
STEPHEN W  I can't say for sure, but I had an A350 and it worked on that. I now have a A65 and it works with the 18-70mm lens. I tried it on an 18 - 55 lens and couldn't get it to lock on so there may be some lenses that it won't work with. Otherwise the picture quality is fair but light drop off is substantial.
Shopper  Does anyone know how well this teleconverter works with a Tamron 18-250 Telephoto?
DONALD P  Yes it will work in BRIGHT light, it may not AF in all situations. Remember you will have a max aperture of f 7. I've used it on my Sigma 70-300 with acceptable results.
