For the money this TC is great and it frequently amazes me. I use it exclusively with my Nikkor 80-200 ED F2.8 and D700 for wildlife and some action work. Its important to remember with any TC that if your object lens is not sharp your TC will not magically make it better...it simply multiplies what you give it. For example the 80-200 2.8 is somewhat soft at 200mm irrespective of the aperture , whereas is extremely sharp at 80-135. So put the tamron on set the zoom to 105 and hey presto its real sharp at 200mm equivalent....albeit 2 stops slower.
Have a look at the shot below: this was taken with the TC on and is a 50% crop from the original photo.

where it comes unstuck is with focus speed. I am not sure why but physically it seems to slow the focus motor down but in average conditions its capable of keeping up with a flying Gannet once the D700 locks on:-

By comparison I have used the Nikkor 300mm F4 with a 1.4 Nikkor TC in similar situations and its focus performance overall is inferior.
Its annoying it doesn't report the actual aperture as that screws up the EXIF. the only other issue is some CA but its not really bad.
Note its probably a Kenko clone or perhaps vice versa
