made my 300mm f2.7 to 520 mm

price will not work with all lense

I have not tried the new 2x but I've heard the 1.7 was the best overall lens and I can say it works perfect for me. no distortion, f stop is still fine for any thing outdoors or well lit indoors.

I bought a TC-17E II as a used product from a respected online vendor. After using it with my Nikkor 200-500mm zoom lens for a bit over a year I came to the conclusion that perhaps the converter needed to be serviced, so I sent it back to Nikon and they found the converter to meet factory standards,...
