"I've been using my D7000 for over a year now, and it's going on strong. No issues with the build quality at all. The Battery life is very very good (usually avg around 1500 shots or more with lots of reviewing). The twin card slots are a definite plus! Coupled with a fast card (eg.

I am taking on field photos of college lacrosse games and trying to get up close and detailed photos for the players, the school and the parents. This teleconverter allowed me to get a bit closer with my 70-200mm f/2.8 Nikon lens and make better use of the whole field.

I bought this (not from amazon) to use with my 70-200 2.8 VR2, after reading good reviews online. The thing is, there is a great impact on image quality, so much so that I just don't use it. Images are soft, even stopped down 2 stops, and lack contrast.

Works as intended. Pairs well with my 70-200mm 2.8

Coupled with fast primes this TC really shines. Outstanding IQ/AF speed with my 200 f2/300 f2.8 VR's This little addition has actually saved me thousands of dollars not having to purchase a 500...love when that happens!

I would rate the 1.4TC as the only TC that will yield excellent results across the board. The 1.7 is a good compromise, but dont expect it to yield tack-sharp results on every lens. You need to stop many lenses down at least two stops when using this TC to achieve max sharpness.

Good reach; works flawlessly with top-quality glass

Not as sharp as 1.4TC
