This TC-20E III is outstanding when used properly with right lens & body!!
3 December 2013
Summary: Folks, I use this TC-20 with my Nikkor AF-S 200mm F2 VR "CHUBBY STUBBY" AND THAT TC-20 CONVERTS IT TO ONE FAST 400mm lens when used with my D700 body for reaching out and touching somebody. I have used it for football, basketball and water polo with outstanding stop action results. Would not use this with anything higher than a f2.8 pro lens. It truly is well built and does an excellent job for me, I am very pleased with the results.
