Great budget converter if you dont need AF with your nikon lenses.

Summary: I use this Nikon TC-14b 1.4x converter on my Nikon 400mm F3.5 EDIF and Nikon D800. It gives me a 560mm F5 full frame. On that camera with that lens it does not seem to loose much quality with the converter. Maybe if anything a little softer in corners but I am being picky.
Great product, compliments my 300mm f/4 nicely! Extra reach & sharpness!

Summary: Found this item to match up with the 300mm f/4, e/c, to get more reach without buying a 500mm f/4. This combination works quite well and I am completely satisfied, everyone who has a prime tele, needs at least the 1.4 for that extra reach we all want.
Meant f/Nikkor long teles-Works GREAT w/ my Tokina 300

Summary: Did a bit of investigation between Nikon teleconverters and which lenses they were designed to work best with. I own a Tokina SD-ATX 300mm f/2.8 and getting so-so results with my TC-201. Decided the TC14B would be the best way to go and not lose as much sharpness.
Summary: I bought this lens to increase the focal length of my old Nikkor 300mm, f2,8 IF-ED. I have never tried such a lens before, but it proved to be very high quality and it does not affect the picture quality. Excellent lens.
