Nikon AF-S TELECONVERTER TC-14E II Modified The mount tabs have been shaved down to allow use with the AF-S 70-300mm F4.5-5.6 G ED VR. You can search online to find out more details about this modification. I used it with a D7500. There may be some dust inside, but I don't think it affects the image quality. The exterior shows signs of use. The original box and instruction manual are not included. Please consider this a used item and purchase with careful consideration.
