Kenko TelePlus MC7 AF 2.0X DGX Teleconverter
The Kenko TelePlus MC7 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 MC7 features a 7-element, 4-group design with multi-coated lens elements, and fully automatic diaphragm coupling. With the Kenko TelePlus MC7 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 MC7 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.

After reading about this product(mc7 dgx 2x tele) concerning the autofocusing, I thought that I would most definatly have to use the manual focusing because of the semi slow aperature of my Tokina 80-400mm lens f3.5 to 5.6 changing that to f11.(very slow)So I bought it any way for the cheap power it would provide for me shooting wildlife. To my surprise in decent light the autofocus works even at f11! so it definatly exceeded my expectations. The quality seems to be exceptional as well, having taken a few shots of far away birds and the big glowing moon some images are a bit soft but I definatly can work with it, heading to Alaska for the big test.

Put it behind my 70-200 2.8 VR2. I should be ashamed of myself to put such a [*] behind my beauty. Major loss of IQ (Image Quality), Loss of Sharpness, colors degrade, I could go on.The mechanics are totally poor, too. Feels like it is grinding on your bayonette. I felt sorry for my body as well as my lens. Sure enough I could even see marks on the seat after taking it of. Fortunately no damage but it sure felt like it. The VR all of a sudden gets noisy.The only good thing to say is that the camera data are reported correctly (EXIFs) and the focus with a good lens (2.8) works fine. But this is more a function of the camera and lens rather then the converter.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter:
I am very pleased with the MC7 teleconverter. I used it on my D90 with a AF VR Nikkor 80-400mm and it worked as advertised. The the long zoom autofocus works in daylight with good contrast in the focus zone. Using the AF VR 18-200 Nikkor lens and teleconverter, the lens had a more difficult time focusing.
It is worth the manual focus to get the increased focal length

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter:
This is a great extender if you cannot afford the real lens.
Just keep in mind that you need a lot of light for handheld shots.
On my D90 and Nikon 80 200 f2.8 it is sharp; the autofocus and the camera exf data works great.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter:
Works well with my Nikon 180mm 2.8 but autofocus seems a bit goofy with my Tamron 70-200 2.8 Otherwise images turned out pretty good
Attachment to camera body and lens seems like it is not the most secure connection.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter:
I mainly bought it for traveling when it is not practical to carry my 150-500mm zoom lens. Since the front element is deep inside, it is one of the few extenders that can be mounted on my Nikon 18-200mm DX zoom lens. I use it once in a while when 200mm isn't enough. I does reduce slightly the optical resolution, but I don't have to crop as much as if I was using only my 200mm. When stopped down, quality is quite decent. Price is not to bad either.
