Good low price option to extend focal range | Rating:
“I received my TC a few days ago and tested it on my D700 and Nikon 70-200mm f/2.8G ED VR II AF-S NIKKOR Lens For Nikon Digital SLR Cameras. The image quality with this combo suffers slightly (in terms of sharpness), but is pretty good overall. Corner sharpness is really good, given that it’s a 2X TC..” – by Lihkin
Impressive performance for a teleconverter, | Rating:
“I have paired this with the 70-200mm VR II on a D700 and am so far very impressed with the performance. There is some loss of sharpness, but it retains detail far more than I was expecting, and it is much, much, much better than the TC-20E II. Given that the III is also smaller and lighter makes it well worth the extra money in my book. AF with this combination is still fast and sure, about on par with the 70-300mm VR if not a bit snappier and with less hunting, and is fast enough for sports in daylight..” – by John Mechalas

“I compared the Nikon 300mm 2.8 AF VR1 to a Nikon 70-200mm 2.8 AF VR1 with TC-20 III (Actual 310mm). When compared against the 300 2.8 shot, corners and center were almost as sharp as 300mm. However the color & contrast is better on the 300mm 2.8 shot than the TC-20. Less saturation and richness w/ TC. While the 300 2.8 is sharper than the 70-200 with TC-20, the TC-20 image is by no means a bad photo.” – by R. Adams
