Kenko TelePlus MC7 AF 2.0X DGX Teleconverter for Sony Alpha Digital SLRs
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.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter for Sony Alpha Digital SLRs:
Built with 8 electrical pins for all data to pass through, not just AF. At least 2 f stops lost so depending on the lens, AF may not work but functional with MF. Great for the price.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter for Sony Alpha Digital SLRs:
It does what it has to, zooms awesomely. But lacks sharpness. Most of the clicks regardless of low light or more light, the pic lacks sharpness and the focus is reduced too. Not every picture you think is focused is actually focused.
But the zoom is very appreciative. If you get the perfect focus, the perfect sharpness, the pic is worth the capture.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter for Sony Alpha Digital SLRs:
The quality of the picture is very good. But the attachment gives a very rusty creeeeeeek sound. Yes, you hear it right, when it focuses it gives a very usual sound like the one we get when we move a rusty object. The focus is not very smooth. But the quality of the picture gives the satisfaction of buying it. My sony 18-55 SAM lens does not fit the teleconverter though it says it is compatible.

Comments about Kenko TelePlus MC7 AF 2.0X DGX Teleconverter for Sony Alpha Digital SLRs:
Use this mostly to extend the reach of my Tamron 70-200 2.8 for bird/wildlife photography of the smaller creatures. I was pleased to see that this converter retains very good center sharpness and good edge sharpness. All of the camera functions work properly (Sony A55V), and the brightness with a 2.8 lens is good enough for decent autofocus when shooting wildlife. Very happy with the purchase. The steel mount is smooth, and it seems to be a durable piece of equipment.

Used this to extend a 70 - 200 mm F2.8 Tamron to 400 mm. Still auto focuses and have not noticed any quality drop off.
