I bought this teleconverter to use with my macro lens,to increase their magnifacation. What a supprise I got when I decided to try it on my Nikon AF 70-300 VR lens. When I couple this lens and the teleconverter to my D300s, I wind up with a VR lens...

Just bought this new, and having focus searching problem on my Sigma f2.9 70-200HSM. Will not stop searching. Does not do this with my other 'shorter' zoom - Nikon 18-79, Sigma 24-135, & Tamron17-50.

This complements my Kenko 300DG pro 2X well giving me a 98-280 and 140-400. Needs to be stopped down 2/3 stops for optimal resolving power.

I use it to extend my Canon EF 135mm F2 L to an 189mm F2.8, which means that I (almost) have 200 mm length without noticeable loss of AF speed or IQ.

Compared to the 1.4 Canon TC, it has a lot of pros : it is light, black, can be used on much more lenses and more than 2 times cheaper !

The king of all the Tcs!
