Kenko MC7-AF2.0DGX-N overview

  • 1Description

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.

    Kenko MC7-AF2.0DGX-N reviews

    TelePlus MC7 AF 2.0X DGX Teleconverter is rated 3.9 out of 5 by 25.
    Rated 5 out of 5 by from Good ol cheap power! 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.

    Rated 1 out of 5 by from Disappointing 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.

    Rated 4 out of 5 by from works as expected works as I expected just have to use manual focus, I am using a AF Zoom Nikkor 70-300mm f/4-5.6G Lens which is out of specs, but works.

    Rated 4 out of 5 by from Solid for the Price Provides great zoom capabilities, but it is restricted in its ability to accurately and quickly autofocus. You're better off in manual mode - therefore this is not a very good product for sports and fast action shots. On my D90 using a 18-200mm light metering is off favoring overly exposed shots by 2-3stops. Easily remedied but just something to note. Cheap way to get a more powerful zoom lens in a compact package.

    Rated 4 out of 5 by from Very decent optic for traveling 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.

    Rated 5 out of 5 by from Calibrate Lens/Diopler Adjustment/Shutter I own the 1.4 from this company, and I will order this 2X soon. Reason: The 1.4 is tact sharp. The reason photographers here can't get their images sharp is for three reasons. One, even lenses and cameras from the factory must be calibrated to maximize sharpness (go on Youtube to learn how to calibate each lens to each camera you have, I have two cameras and five lenses, so I calibrated all five to both cameras, and the same with the teleconverter). Two, it is the easiest thing to bumb the diopler dial off (on Nikons) a click or more. You whom manually focus may be off one click on your diopler, that's all it takes. Three, the rule of shutter speed to focal length, i.e., 600mm - 1/640 second is rated for pros. This speed to shutter ratio should be nearly doubled for amateurs, i.e., 600mm - 1/1000+ second. Finally, my advice is for getting the sharpest images do three more things: One, use a tripod, two, lock up your mirror, three study snippers - they will teach you how to depress a trigger, i.e., a shutter button properly. Good luck, and I hope that helps all here..... :) Buy the teleconverter, learn these things, be a better photographer.
